Add the optional counterweight system and the published capacity rises to 44 lb (20 kg).\u003c\/p\u003e\n\n\u003cp\u003eThat combination makes the HEM27 especially attractive for portable astrophotography. A small-to-medium refractor, cooled camera, filter wheel, focuser, guider, and the rest of a normal imaging train can ride on a mount light enough to carry outside in one hand.\u003c\/p\u003e\n\n\u003cp\u003eThe HEM27 gets there with a hybrid drive system. Right ascension uses a strain-wave gear for high torque in a compact package, while declination uses a backlash-free worm-and-belt drive. The result is a mount designed around portability without abandoning the guiding and control features expected from a modern equatorial system.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e29.7 lb counterweight-free payload.\u003c\/strong\u003e Carry up to 13.5 kg without a conventional counterweight shaft and stack of weights.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eOnly 8.15 lb with the saddle installed.\u003c\/strong\u003e The payload-to-mount-weight ratio is approximately 3.65:1.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eUp to 44 lb with a counterweight.\u003c\/strong\u003e Add the optional shaft and counterweight when a heavier or more demanding telescope configuration calls for additional capacity.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eHybrid drive system.\u003c\/strong\u003e The RA axis uses a strain-wave drive while DEC uses iOptron's backlash-free worm-and-belt system.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e360-second RA gear period.\u003c\/strong\u003e The standard HEM27 does not include a high-precision RA encoder, so long-exposure imagers should plan on guiding when their image scale requires it.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eGo2Nova 8409 hand controller included.\u003c\/strong\u003e Standalone GoTo control with an approximately 212,000-object database and nine slew speeds up to 6° per second.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Wi-Fi through the hand controller.\u003c\/strong\u003e The 8409 provides wireless connectivity for compatible applications such as iOptron Commander Lite and SkySafari.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eComputer control.\u003c\/strong\u003e Use iOptron Commander and ASCOM on Windows or compatible third-party INDI software on other platforms.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eIntegrated ST-4 autoguider port.\u003c\/strong\u003e Traditional guiding is supported in addition to software-based pulse guiding.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003ePower and USB pass-through.\u003c\/strong\u003e The mount provides 12V accessory outputs and USB 2.0 pass-through to the saddle, helping keep camera and accessory cabling close to the telescope.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eElectronic friction brake.\u003c\/strong\u003e Designed to stop the mount safely during a planned or unexpected interruption in power.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAutomatic zero-position search.\u003c\/strong\u003e Built-in sensing allows the mount to locate its reference position electronically.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eVixen\/Losmandy-D convertible saddle.\u003c\/strong\u003e The same saddle accepts either standard, although changing between them requires reconfiguring the saddle hardware.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eSoft carrying case included.\u003c\/strong\u003e Appropriate for a mount whose biggest advantage is how easily it travels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy iOptron Calls It a Hybrid\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27 is not simply a smaller version of a conventional German equatorial mount, and it is not a dual-strain-wave mount either.\u003c\/p\u003e\n\n\u003cp\u003eThe right-ascension axis uses strain-wave gearing. That is the axis doing the continuous tracking work, and the compact, high-torque drive is what allows the mount to carry a substantial payload without requiring an equally substantial counterweight on the other side.\u003c\/p\u003e\n\n\u003cp\u003eDeclination takes a different approach. iOptron uses a worm-and-belt drive designed for backlash-free operation, with a gear switch that allows the DEC axis to be released for balancing.\u003c\/p\u003e\n\n\u003cp\u003eNo RA balancing is required. That is one of the biggest practical differences between setting up the HEM27 and setting up a traditional German equatorial mount.\u003c\/p\u003e\n\n\u003ch3\u003e29.7 Pounds Without a Counterweight\u003c\/h3\u003e\n\n\u003cp\u003eThe headline payload number is 29.7 lb, but the geometry of the telescope matters along with the scale weight.\u003c\/p\u003e\n\n\u003cp\u003eiOptron bases the rating on the payload's center of gravity being approximately 200mm from the RA rotation axis, or an optical tube roughly 220mm in diameter. A compact 25-pound imaging rig and a long 25-pound refractor do not put the same load on the drive.\u003c\/p\u003e\n\n\u003cp\u003eThat makes the HEM27 a particularly natural match for compact refractors and astrographs where the mass stays relatively close to the mount. Longer tubes, large rear-mounted imaging trains, and wind-sensitive telescopes deserve more margin below the published payload rating.\u003c\/p\u003e\n\n\u003cp\u003eIf the system needs more capacity, the optional counterweight shaft and weight increase the published rating to 44 lb.\u003c\/p\u003e\n\n\u003ch3\u003eThis Version Does Not Include iPolar\u003c\/h3\u003e\n\n\u003cp\u003eThe H272 is the standard HEM27 without iPolar. There is no conventional optical polar scope built into the mount either.\u003c\/p\u003e\n\n\u003cp\u003eThat is not necessarily a disadvantage if you already polar align through imaging software. SharpCap, NINA, ASIAIR, PHD2, and other software-based methods can all provide a practical path to polar alignment without looking through a polar scope.\u003c\/p\u003e\n\n\u003cp\u003eIf you prefer iOptron's electronic polar-alignment system, iPolar is also available for the HEM27. iOptron currently lists the HEM15, HEM27, and HEM44 among the supported mounts for its HEM-specific iPolar configuration.\u003c\/p\u003e\n\n\u003cp\u003eThe choice between this model and the iPolar-equipped HEM27 therefore comes down mostly to workflow. If you already use plate solving or another camera-based polar-alignment routine, the H272 lets you avoid paying for a second alignment system you may never use.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt to Be Guided\u003c\/h3\u003e\n\n\u003cp\u003eThe standard HEM27 does not have the high-precision RA encoder found in the HEM27EC.\u003c\/p\u003e\n\n\u003cp\u003eFor long-exposure deep-sky imaging, the sensible approach is to guide it. The mount provides an ST-4 autoguider port and also supports software-based guiding through compatible computer-control systems.\u003c\/p\u003e\n\n\u003cp\u003eStrain-wave mounts can behave differently from conventional worm-drive mounts because the RA tracking rate can change more quickly through portions of the gear cycle. That often makes relatively frequent guide corrections useful, but there is no one exposure time or aggressiveness setting that belongs on every HEM27.\u003c\/p\u003e\n\n\u003cp\u003eSeeing, guide-camera sensitivity, telescope focal length, image scale, and the rigidity of the tripod all affect the result. Tune the guider to the actual stars in your exposures rather than chasing somebody else's RMS number.\u003c\/p\u003e\n\n\u003ch3\u003eClean Cabling at the Telescope\u003c\/h3\u003e\n\n\u003cp\u003eA portable mount loses some of its appeal if every setup involves rebuilding a nest of cables.\u003c\/p\u003e\n\n\u003cp\u003eThe HEM27 routes its main cabling internally and provides USB and 12V pass-through connections near the saddle. A camera or accessory can therefore use short cables at the telescope instead of having every connection hang across the moving axes.\u003c\/p\u003e\n\n\u003cp\u003eiOptron provides two 12V outputs with a combined maximum of 4A along with USB 2.0 pass-through. The arrangement does not replace a full imaging power-management system for every rig, but it can substantially simplify a typical portable setup.\u003c\/p\u003e\n\n\u003ch3\u003eGo2Nova Control and Wi-Fi\u003c\/h3\u003e\n\n\u003cp\u003eThe included Go2Nova 8409 hand controller gives the HEM27 standalone GoTo control with an approximately 212,000-object database and nine slew speeds up to 6° per second.\u003c\/p\u003e\n\n\u003cp\u003eWi-Fi is provided through the hand controller, so keep the handset connected when you want to control the mount wirelessly through iOptron Commander Lite, SkySafari, or another compatible system.\u003c\/p\u003e\n\n\u003cp\u003eComputer control is also available through USB. Windows users can work through iOptron Commander and ASCOM, while third-party INDI support provides additional options on macOS, Linux, and Raspberry Pi systems.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eHEM27 owners on Cloudy Nights tend to come back to the same advantage: portability changes how often the mount actually gets used.\u003c\/p\u003e\n\n\u003cp\u003eOne longtime owner who also uses an HEQ5 described the HEM27's altitude and azimuth locking bolts as an annoyance, but considered them a small price to pay for a mount that could simply be picked up and carried outside instead of living on wheeled bars in the garage.\u003c\/p\u003e\n\n\u003cp\u003eThat complaint about the locking hardware is worth knowing before the first night out. The altitude and azimuth locks use socket-head hardware rather than large hand knobs, and some owners keep a T-handle hex wrench with the mount or replace the hardware with lever-style alternatives.\u003c\/p\u003e\n\n\u003cp\u003eOwners also confirm that the saddle deserves a little explanation. It accepts both Vixen and Losmandy-D plates, but it is not a modern clamp that instantly accepts either size. Changing from its default Vixen configuration to Losmandy-D requires moving the fixed block and flipping the locking block.\u003c\/p\u003e\n\n\u003cp\u003eGuiding reports are more useful than quoting one impressive RMS number. Standard non-EC HEM27 owners report successful multi-minute imaging when the mount is guided, but results vary with image scale, setup, seeing, and guiding configuration. That is the right expectation for this version: guide it well and let the low mount weight be the reason you chose it.\u003c\/p\u003e\n\n\u003ch3\u003eA Few Setup Details Worth Knowing\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27 has two latitude ranges: 15–41° and 39–65°. Switching between them requires relocating the latitude position bolt and locking screws, so it is something to do at home rather than discovering after dark at a distant observing site.\u003c\/p\u003e\n\n\u003cp\u003eThe convertible saddle also ships in its Vixen configuration. If your telescope uses a Losmandy-D plate, convert the saddle before the first observing session and leave it configured for the dovetail standard you normally use.\u003c\/p\u003e\n\n\u003cp\u003eWith a longer refractor or a deep imaging train, a MiniPier can also be useful for keeping the camera and focuser clear of the tripod legs near the meridian and zenith.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eiOptron HEM27 hybrid strain-wave equatorial mount head\u003c\/li\u003e\n\u003cli\u003eVixen\/Losmandy-D convertible dovetail saddle\u003c\/li\u003e\n\u003cli\u003eGo2Nova 8409 hand controller\u003c\/li\u003e\n\u003cli\u003e6P6C coiled hand-controller cable\u003c\/li\u003e\n\u003cli\u003e12V\/5A AC adapter for indoor use\u003c\/li\u003e\n\u003cli\u003eUSB cable for mount control\u003c\/li\u003e\n\u003cli\u003eSoft EVA carrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot included:\u003c\/strong\u003e tripod, counterweight shaft and counterweight, or iPolar electronic polar scope.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can the HEM27 carry without a counterweight?\u003c\/strong\u003e\u003cbr\u003e\niOptron rates it for 29.7 lb (13.5 kg) without a counterweight. The rating assumes the payload center of gravity is approximately 200mm from the RA axis, so telescope geometry matters along with total weight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can it carry with a counterweight?\u003c\/strong\u003e\u003cbr\u003e\nWith the optional counterweight shaft and weight, iOptron raises the published payload rating to 44 lb (20 kg), subject to the same payload-geometry considerations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this HEM27 include iPolar?\u003c\/strong\u003e\u003cbr\u003e\nNo. The H272 is the standard HEM27 without iPolar. The mount also does not include a conventional optical polar scope. You can polar align with compatible imaging software or add an appropriate iPolar configuration separately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I add iPolar later?\u003c\/strong\u003e\u003cbr\u003e\nYes. iOptron currently lists the HEM27 as compatible with its HEM-specific iPolar configuration. Make sure you order the correct version for the HEM27.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eShould I guide the standard HEM27?\u003c\/strong\u003e\u003cbr\u003e\nFor typical long-exposure deep-sky imaging, yes. The standard HEM27 does not include the high-precision RA encoder of the HEM27EC. The mount supports both ST-4 and software-based guiding.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan it image unguided?\u003c\/strong\u003e\u003cbr\u003e\nShort exposures at forgiving image scales may be possible, but this is not the version to buy specifically for long unguided imaging. If encoder-assisted unguided tracking is a major goal, the HEM27EC is the model designed around that capability.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it work with ASIAIR?\u003c\/strong\u003e\u003cbr\u003e\nHEM27 owners use the mount successfully with ASIAIR systems, although connection methods have varied with firmware and ASIAIR revisions. Community reports include both Wi-Fi through the 8409 handset and connections using the handset as the communication path. Treat ASIAIR compatibility as a system-integration question rather than assuming every connection method behaves identically.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it work with NINA?\u003c\/strong\u003e\u003cbr\u003e\nYes. On Windows, the HEM27 can be controlled through iOptron Commander and ASCOM, allowing compatible applications such as NINA and PHD2 to communicate with the mount.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the saddle really Vixen and Losmandy compatible?\u003c\/strong\u003e\u003cbr\u003e\nYes, but it is convertible rather than instantly dual-width. The saddle ships configured for Vixen plates. Changing it to Losmandy-D requires repositioning and flipping parts of the saddle assembly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat tripod fits it?\u003c\/strong\u003e\u003cbr\u003e\nThe HEM27 is compatible with iOptron's LiteRoc tripod for the CEM26\/HEM27\/GEM28\/HAE29 family as well as compatible carbon-fiber tripod options. A matching MiniPier is useful when additional telescope-to-tripod clearance is needed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat power does it require?\u003c\/strong\u003e\u003cbr\u003e\nThe mount uses 12V DC at up to 5A through a 5.5\/2.5mm center-positive input. A 100–240V AC adapter for indoor use is included.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27 makes the most sense for an imager who is tired of carrying more mount than telescope.\u003c\/p\u003e\n\n\u003cp\u003eAt 8.15 lb with the saddle installed, it is light enough to carry outside without turning setup into a project, yet the 29.7 lb counterweight-free rating gives it room for a very capable portable imaging system.\u003c\/p\u003e\n\n\u003cp\u003eThe hybrid drive is part of what makes that possible: strain-wave gearing handles RA while the backlash-free worm-and-belt system handles DEC. The included 8409 controller provides standalone GoTo and Wi-Fi, saddle-mounted power and USB help clean up the imaging train, and the electronic brake and zero-position search take care of some of the details you would expect from a much heavier mount.\u003c\/p\u003e\n\n\u003cp\u003eThis H272 version is the one to choose if you already polar align with software and do not need iPolar built into the mount. Plan to guide it, keep the telescope geometry sensible, and the HEM27 gives you something that matters every clear night: a capable imaging mount that is easy enough to actually take outside.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

The H272A adds iPolar directly to the mount.\u003c\/p\u003e\n\n\u003cp\u003eInstead of looking through a small optical reticle and placing Polaris at a calculated position, iPolar photographs the sky around the celestial pole and plate solves the field. The software then shows the relationship between the mount's RA axis and the true celestial pole.\u003c\/p\u003e\n\n\u003cp\u003eYou make the altitude and azimuth adjustments while watching the result on screen. Bring the mount-axis indicator onto the pole indicator and the alignment is complete.\u003c\/p\u003e\n\n\u003cp\u003ePolaris itself does not need to be visible. That can be genuinely useful in a backyard where a tree branch or roofline blocks the star even though enough of the surrounding polar-region sky remains open for the software to identify the field.\u003c\/p\u003e\n\n\u003cp\u003eThe same principle applies in the Southern Hemisphere. You do not have to identify Sigma Octantis or change to a different reticle pattern.\u003c\/p\u003e\n\n\u003ch3\u003e30-Arcsecond Polar Alignment\u003c\/h3\u003e\n\n\u003cp\u003eiOptron specifies iPolar alignment precision at approximately 30 arcseconds.\u003c\/p\u003e\n\n\u003cp\u003eThat level of accuracy is far beyond what is needed simply for GoTo pointing. For astrophotography, however, good polar alignment reduces declination drift, helps limit field rotation, and gives the guider less unnecessary work to do over a long imaging session.\u003c\/p\u003e\n\n\u003cp\u003eIt is important to separate polar alignment from tracking performance. iPolar accurately aligns the mount's RA axis with the celestial pole; it does not remove periodic error from the drive. The standard HEM27 is still a non-encoder strain-wave mount, so demanding long-exposure imaging should normally be guided.\u003c\/p\u003e\n\n\u003ch3\u003eWhy iOptron Calls It a Hybrid\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27 is not a conventional German equatorial mount and it is not a dual-strain-wave mount either.\u003c\/p\u003e\n\n\u003cp\u003eRight ascension uses a strain-wave drive. That is the axis doing the continuous tracking work, and the compact, high-torque design is what lets the mount carry a substantial payload without requiring an equally substantial counterweight on the other side.\u003c\/p\u003e\n\n\u003cp\u003eDeclination uses a different solution: iOptron's backlash-free worm-and-belt system. The DEC axis includes a gear switch so it can be released for balancing.\u003c\/p\u003e\n\n\u003cp\u003eNo RA balancing is required. That is one of the biggest practical differences between setting up the HEM27 and setting up a traditional German equatorial mount.\u003c\/p\u003e\n\n\u003ch3\u003e29.7 Pounds Without a Counterweight\u003c\/h3\u003e\n\n\u003cp\u003eThe published payload is 29.7 lb, but telescope geometry matters along with scale weight.\u003c\/p\u003e\n\n\u003cp\u003eiOptron bases the rating on the payload's center of gravity being approximately 200mm from the RA rotation axis, or an OTA roughly 220mm in diameter. A compact 25-pound imaging system and a long 25-pound refractor do not place the same load on the mount.\u003c\/p\u003e\n\n\u003cp\u003eThat makes the HEM27 particularly natural under compact refractors and astrographs where the mass remains relatively close to the RA axis. Longer tubes, large rear-mounted imaging trains, and wind-sensitive systems deserve more margin below the published payload rating.\u003c\/p\u003e\n\n\u003cp\u003eIf the system needs more capacity, the optional counterweight shaft and weight raise the published rating to 44 lb.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt to Be Guided\u003c\/h3\u003e\n\n\u003cp\u003eThe standard HEM27 does not include the high-precision RA encoder found in the HEM27EC.\u003c\/p\u003e\n\n\u003cp\u003eFor long-exposure deep-sky imaging, guiding is the sensible approach. The mount provides an ST-4 autoguider port and also supports software-based guiding through compatible computer-control systems.\u003c\/p\u003e\n\n\u003cp\u003eStrain-wave mounts can behave differently from conventional worm-drive mounts because their tracking rate can change relatively quickly through portions of the gear cycle. That often makes relatively frequent guide corrections useful, but there is no single exposure time or aggressiveness setting that belongs on every HEM27.\u003c\/p\u003e\n\n\u003cp\u003eSeeing, guide-camera sensitivity, focal length, image scale, wind, and tripod rigidity all affect the result. Tune the guider from the actual stars in your exposures rather than trying to reproduce somebody else's RMS number.\u003c\/p\u003e\n\n\u003ch3\u003eClean Cabling at the Telescope\u003c\/h3\u003e\n\n\u003cp\u003eA portable mount loses some of its appeal if every setup involves rebuilding a web of cables.\u003c\/p\u003e\n\n\u003cp\u003eThe HEM27 routes its main wiring internally and provides two 12V outputs plus USB 2.0 pass-through near the saddle. Cameras and accessories can therefore use short cables at the telescope instead of having every connection hang across the moving axes.\u003c\/p\u003e\n\n\u003cp\u003eThe two 12V outputs provide up to 4A combined. That does not replace a full power-management system for every imaging rig, but it can substantially simplify a typical portable setup.\u003c\/p\u003e\n\n\u003ch3\u003eGo2Nova Control and Wi-Fi\u003c\/h3\u003e\n\n\u003cp\u003eThe included Go2Nova 8409 hand controller gives the HEM27 standalone GoTo control with an approximately 212,000-object database and nine slew speeds up to 6° per second.\u003c\/p\u003e\n\n\u003cp\u003eWi-Fi is provided through the hand controller, so keep the handset connected when you want to operate the mount wirelessly through iOptron Commander Lite, SkySafari, or another compatible application.\u003c\/p\u003e\n\n\u003cp\u003eComputer control is also available through USB. Windows users can work through iOptron Commander and ASCOM, while third-party INDI support provides additional options on macOS, Linux, and Raspberry Pi systems.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eHEM27 owners on Cloudy Nights repeatedly come back to the same benefit: the low mount weight makes the system much easier to actually use.\u003c\/p\u003e\n\n\u003cp\u003eOne longtime owner who also uses an HEQ5 described the HEM27's altitude and azimuth locking bolts as an annoyance, but considered them a small price to pay for a mount he could simply pick up and carry outside instead of keeping on wheeled bars in the garage.\u003c\/p\u003e\n\n\u003cp\u003eThat complaint is worth knowing before the first night out. The altitude and azimuth locks use socket-head hardware rather than large hand knobs, so keeping the correct hex tool with the mount makes setup much easier.\u003c\/p\u003e\n\n\u003cp\u003eOwners also point out that the Vixen\/Losmandy saddle is convertible rather than instantly dual-width. Switching between the two standards requires moving and flipping parts of the saddle, so it is a job best done indoors before heading to the field.\u003c\/p\u003e\n\n\u003cp\u003eiPolar itself has a strong following among iOptron users. Experienced owners report that it is quick and repeatable once properly calibrated, and some verify the finished alignment afterward with PHD2 Guiding Assistant. That is useful context: iPolar is primarily about making a good polar alignment fast and repeatable, not about replacing guiding or solving every tracking issue downstream.\u003c\/p\u003e\n\n\u003ch3\u003eA Few Setup Details Worth Knowing\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27 has two normal latitude ranges: 15–41° and 39–65°. Switching between them requires relocating hardware inside the latitude adjustment assembly, so it is something to do at home rather than discovering after dark at a distant observing site.\u003c\/p\u003e\n\n\u003cp\u003eThe saddle also ships configured for Vixen dovetails. If your telescope uses a Losmandy-D plate, convert the saddle before the first observing session and leave it set for the dovetail standard you normally use.\u003c\/p\u003e\n\n\u003cp\u003eWith a longer refractor or deep imaging train, a MiniPier can also be useful for keeping the camera and focuser clear of the tripod legs near the meridian and zenith.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eiOptron HEM27 hybrid strain-wave equatorial mount head\u003c\/li\u003e\n\u003cli\u003eFactory-installed iPolar electronic polar scope\u003c\/li\u003e\n\u003cli\u003eVixen\/Losmandy-D convertible dovetail saddle\u003c\/li\u003e\n\u003cli\u003eGo2Nova 8409 hand controller\u003c\/li\u003e\n\u003cli\u003e6P6C coiled hand-controller cable\u003c\/li\u003e\n\u003cli\u003e12V\/5A AC adapter for indoor use\u003c\/li\u003e\n\u003cli\u003eUSB cable for mount control\u003c\/li\u003e\n\u003cli\u003eMini-USB cable for iPolar\u003c\/li\u003e\n\u003cli\u003eSoft EVA carrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot included:\u003c\/strong\u003e tripod, counterweight shaft, or counterweight.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between this HEM27 and the standard HEM27?\u003c\/strong\u003e\u003cbr\u003e\nThe H272A includes iOptron's iPolar electronic polar scope built into the mount. The H272 uses the same basic hybrid drive and has the same payload rating but does not include a polar scope.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need to see Polaris to use iPolar?\u003c\/strong\u003e\u003cbr\u003e\nNo. iPolar plate solves the surrounding polar-region star field, so Polaris itself does not need to be visible. Enough surrounding sky still needs to be visible for the camera and software to identify the field.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow accurately can iPolar align the mount?\u003c\/strong\u003e\u003cbr\u003e\niOptron specifies maximum polar-alignment precision of approximately 30 arcseconds.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes iPolar require a computer?\u003c\/strong\u003e\u003cbr\u003e\nYes. iOptron's official iPolar software runs on a Windows computer. The iPolar camera connects through its Mini-USB port during polar alignment. Once alignment is complete, the iPolar computer connection is no longer required simply for the mount to track.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can the HEM27 carry without a counterweight?\u003c\/strong\u003e\u003cbr\u003e\niOptron rates it for 29.7 lb (13.5 kg) without a counterweight. The rating assumes the payload center of gravity is approximately 200mm from the RA axis, so telescope geometry matters along with total weight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can it carry with a counterweight?\u003c\/strong\u003e\u003cbr\u003e\nWith the optional counterweight shaft and weight, iOptron raises the published payload rating to 44 lb (20 kg), subject to the same payload-geometry considerations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eShould I guide the standard HEM27?\u003c\/strong\u003e\u003cbr\u003e\nFor typical long-exposure deep-sky imaging, yes. This HEM27 does not include the high-precision RA encoder of the HEM27EC. The mount supports both ST-4 and software-based guiding.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes iPolar replace guiding?\u003c\/strong\u003e\u003cbr\u003e\nNo. iPolar handles polar alignment. Guiding corrects tracking errors while the mount is operating. They solve different problems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the mount work with ASIAIR?\u003c\/strong\u003e\u003cbr\u003e\nHEM27 owners use the mount successfully with ASIAIR systems, although connection methods can vary with ASIAIR and mount firmware revisions. The mount's Wi-Fi is provided through the 8409 hand controller.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it work with NINA?\u003c\/strong\u003e\u003cbr\u003e\nYes. On Windows, the HEM27 can be controlled through iOptron Commander and ASCOM, allowing compatible applications such as NINA and PHD2 to communicate with the mount.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the saddle really Vixen and Losmandy compatible?\u003c\/strong\u003e\u003cbr\u003e\nYes, but it is convertible rather than instantly dual-width. The saddle ships configured for Vixen plates. Changing it to Losmandy-D requires repositioning and flipping parts of the saddle assembly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat tripod fits it?\u003c\/strong\u003e\u003cbr\u003e\nThe HEM27 is compatible with iOptron's LiteRoc tripod for the CEM26\/HEM27\/GEM28\/HAE29 family as well as compatible carbon-fiber tripod options. A matching MiniPier is useful when additional telescope-to-tripod clearance is needed.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27 with iPolar is for the imager who wants to remove two common excuses for leaving the telescope inside: a heavy mount and an awkward polar-alignment routine.\u003c\/p\u003e\n\n\u003cp\u003eThe mount head weighs just 8.15 pounds, carries 29.7 pounds without a counterweight, and fits into a soft case small enough to travel easily. The built-in iPolar camera replaces the traditional polar-scope reticle with plate solving and on-screen adjustment guidance, without requiring Polaris itself to be visible.\u003c\/p\u003e\n\n\u003cp\u003eUnderneath that convenience is still a capable imaging mount: strain-wave RA, backlash-free worm-and-belt DEC, Go2Nova control, Wi-Fi, guiding support, saddle-mounted power and USB, an electronic brake, and automatic zero-position search.\u003c\/p\u003e\n\n\u003cp\u003ePlan to guide it for serious long-exposure work, keep the telescope geometry sensible, and the HEM27 with iPolar gives you a portable imaging system that is quick enough to set up that a clear weeknight can actually become an imaging night.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

On a standard non-encoder strain-wave mount, the guider often has to make relatively frequent RA corrections to keep up with those changes.\u003c\/p\u003e\n\n\u003cp\u003eThe HEM27EC adds another layer of feedback. Its high-precision encoder continuously measures the RA axis and allows the mount to correct much of that tracking error in real time.\u003c\/p\u003e\n\n\u003cp\u003eiOptron says the resulting accuracy is good enough that many users may choose to image without guiding, particularly with shorter focal lengths and more forgiving image scales.\u003c\/p\u003e\n\n\u003cp\u003eThat does not mean every HEM27EC automatically becomes an unguided imaging mount. Focal length, pixel scale, exposure length, polar alignment, payload geometry, seeing, and the level of star quality you expect all still matter.\u003c\/p\u003e\n\n\u003cp\u003eThe better way to think about the encoder is that the RA axis is already correcting itself before an external guider enters the picture.\u003c\/p\u003e\n\n\u003ch3\u003eWhy the EC Version Can Guide Differently\u003c\/h3\u003e\n\n\u003cp\u003eThe encoder also changes the way you may want to guide the mount.\u003c\/p\u003e\n\n\u003cp\u003eOn a non-encoder strain-wave mount, short guide exposures are often useful because the guider has to react quickly to the RA tracking error. That can become inconvenient with an off-axis guider, where guide stars may be too faint for extremely short exposures.\u003c\/p\u003e\n\n\u003cp\u003eiOptron specifically recommends a different strategy with the high-precision encoder version. Because the encoder is already handling the faster RA error internally, external guide corrections can be spaced farther apart and used primarily to correct slower effects such as polar-alignment error, atmospheric refraction, and flexure.\u003c\/p\u003e\n\n\u003cp\u003eGuide cadences in the neighborhood of 5 to 10 seconds are a useful starting point suggested by iOptron for its encoder-equipped strain-wave mounts. That is not a universal setting, but it illustrates an important EC advantage: the guider can spend more time collecting signal while the encoder continues controlling RA between guide corrections.\u003c\/p\u003e\n\n\u003cp\u003eThe 8409 hand controller also gives you two RA-guiding choices. “Allow R.A. Guiding” accepts external RA guide corrections while the encoder continues working between them. “Filter R.A. Guiding” ignores external RA guide commands and lets the encoder handle RA while the guider continues correcting declination.\u003c\/p\u003e\n\n\u003cp\u003eWhich approach works best depends on the telescope and imaging system. Judge the result from the stars in the actual subframes rather than trying to produce the smallest possible RMS number on a guide graph.\u003c\/p\u003e\n\n\u003ch3\u003eiPolar Completes the Package\u003c\/h3\u003e\n\n\u003cp\u003eThe H274A adds iOptron's electronic polar scope directly to the HEM27EC.\u003c\/p\u003e\n\n\u003cp\u003eInstead of looking through a conventional polar-scope reticle, iPolar photographs a roughly 13° field around the celestial pole and plate solves the star field. The software then shows the relationship between the mount's RA axis and the true celestial pole.\u003c\/p\u003e\n\n\u003cp\u003eYou make the altitude and azimuth adjustments while watching the result on screen. When the mount-axis indicator and celestial-pole indicator coincide, the polar alignment is complete.\u003c\/p\u003e\n\n\u003cp\u003ePolaris itself does not have to be visible. The same applies to Sigma Octantis in the Southern Hemisphere. Enough of the surrounding polar-region sky still needs to be visible for the software to successfully identify the star field, but you are not dependent on seeing one particular star.\u003c\/p\u003e\n\n\u003cp\u003eiOptron specifies maximum iPolar alignment precision at approximately 30 arcseconds.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Polar Alignment Matters Even More Here\u003c\/h3\u003e\n\n\u003cp\u003eThe RA encoder is very good at correcting right-ascension tracking error. It cannot correct declination drift caused by polar misalignment.\u003c\/p\u003e\n\n\u003cp\u003eThat makes accurate polar alignment especially valuable if you plan to experiment with unguided imaging. The better the polar alignment, the less unwanted DEC movement develops during the exposure while the encoder handles the RA drive.\u003c\/p\u003e\n\n\u003cp\u003eFor guided imaging, good alignment still reduces the amount of declination correction the guider has to make and helps minimize field rotation over long sessions.\u003c\/p\u003e\n\n\u003cp\u003eiPolar and the RA encoder therefore solve two different problems that work particularly well together: iPolar aligns the mount's axis accurately with the sky, while the encoder improves the tracking of that axis once the exposure begins.\u003c\/p\u003e\n\n\u003ch3\u003eUnguided Imaging\u003c\/h3\u003e\n\n\u003cp\u003eThe encoder makes unguided imaging a realistic option to test rather than merely a theoretical possibility.\u003c\/p\u003e\n\n\u003cp\u003eAt shorter focal lengths, HEM27EC owners have reported successful multi-minute unguided exposures with round stars. That can make for an exceptionally compact travel system: telescope, camera, mount, and iPolar without a separate guide scope and guide camera.\u003c\/p\u003e\n\n\u003cp\u003eBut results vary. One system can perform beautifully at 500 or 600mm and become much less forgiving at 1,000mm. Camera pixel size, payload, polar alignment, seeing, and the individual mount all affect the result.\u003c\/p\u003e\n\n\u003cp\u003eAt longer focal lengths or fine image scales, guiding remains the safer way to maximize the percentage of usable subframes.\u003c\/p\u003e\n\n\u003cp\u003eThe encoder's benefit does not disappear when you add a guider. The guider simply begins with much less raw RA tracking error to correct.\u003c\/p\u003e\n\n\u003ch3\u003e29.7 Pounds Without a Counterweight\u003c\/h3\u003e\n\n\u003cp\u003eUnderneath the encoder and iPolar is still one of the lightest mounts capable of carrying a serious astrophotography system.\u003c\/p\u003e\n\n\u003cp\u003eiOptron rates the HEM27EC for 29.7 lb (13.5 kg) without a counterweight while the mount head weighs only 8.15 lb with its saddle installed.\u003c\/p\u003e\n\n\u003cp\u003eThere is an important qualification to that payload number. iOptron bases the rating on the payload's center of gravity being approximately 200mm from the RA rotation axis, or an optical tube around 220mm in diameter.\u003c\/p\u003e\n\n\u003cp\u003eA compact 25-pound astrograph and a long 25-pound refractor therefore do not present the same load to the mount. Longer tubes, large rear-mounted imaging trains, and wind-sensitive systems deserve additional margin below the published rating.\u003c\/p\u003e\n\n\u003cp\u003eThe optional counterweight shaft and weight raise the published payload capacity to 44 lb and can also be useful with certain larger or more demanding configurations even when they remain below the basic counterweight-free rating.\u003c\/p\u003e\n\n\u003ch3\u003eWhy iOptron Calls It a Hybrid\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27EC is neither a conventional German equatorial mount nor a dual-strain-wave mount.\u003c\/p\u003e\n\n\u003cp\u003eRight ascension uses strain-wave gearing because that is where high torque and counterweight-free operation provide the greatest practical advantage.\u003c\/p\u003e\n\n\u003cp\u003eDeclination uses iOptron's worm-and-belt system, which the company describes as backlash-free. The DEC axis includes a gear switch so it can be released for balancing.\u003c\/p\u003e\n\n\u003cp\u003eNo conventional RA balancing is required. That is one of the reasons the HEM27EC can go from carrying case to imaging setup so quickly.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eHEM27EC owners on Cloudy Nights provide a useful reality check on both the encoder and unguided-imaging claims.\u003c\/p\u003e\n\n\u003cp\u003eOne owner tested repeated five-minute unguided exposures at 560mm focal length and reported round stars after dialing in the system. With a heavier and longer refractor, that same owner found that adding a counterweight improved the unguided performance in certain telescope positions.\u003c\/p\u003e\n\n\u003cp\u003eAnother owner approached the HEM27EC hoping the encoder would eliminate guiding at medium focal lengths and ultimately found that guiding was still preferable for his system. What the encoder did allow was a longer guide cadence, making longer-focal-length telescopes and off-axis guiding more practical.\u003c\/p\u003e\n\n\u003cp\u003eThat second experience lines up well with iOptron's own guidance for its high-precision encoder mounts: let the encoder handle the faster RA tracking behavior and use the external guider primarily for the slower errors that remain.\u003c\/p\u003e\n\n\u003cp\u003eThose two owner experiences are not contradictory. They show why the EC model should not be sold with a blanket promise of unguided imaging. The encoder materially improves the RA tracking platform, but the final result still depends on focal length, payload, polar alignment, guiding strategy, and the complete imaging system.\u003c\/p\u003e\n\n\u003ch3\u003eA Few Setup Details Worth Knowing\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27EC shares the same mechanical details as the standard HEM27.\u003c\/p\u003e\n\n\u003cp\u003eThe altitude and azimuth locks use socket-head hardware rather than large hand knobs, so keeping the correct hex tool with the mount makes field setup easier.\u003c\/p\u003e\n\n\u003cp\u003eThe latitude mechanism normally covers two ranges, 15–41° and 39–65°. Moving between them requires relocating hardware, so check the mount configuration before traveling a significant distance north or south.\u003c\/p\u003e\n\n\u003cp\u003eThe saddle is also convertible rather than instantly dual-width. It ships configured for Vixen plates, and converting to Losmandy-D requires repositioning and flipping parts of the saddle assembly.\u003c\/p\u003e\n\n\u003cp\u003eThose aren't reasons to avoid the mount, but they're useful things to know before discovering them under a red flashlight.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eiOptron HEM27EC hybrid strain-wave equatorial mount head\u003c\/li\u003e\n\u003cli\u003eHigh-precision RA encoder with Real-Time PEC\u003c\/li\u003e\n\u003cli\u003eFactory-installed iPolar electronic polar scope\u003c\/li\u003e\n\u003cli\u003eVixen\/Losmandy-D convertible dovetail saddle\u003c\/li\u003e\n\u003cli\u003eGo2Nova 8409 hand controller\u003c\/li\u003e\n\u003cli\u003e6P6C coiled hand-controller cable\u003c\/li\u003e\n\u003cli\u003e12V\/5A AC adapter for indoor use\u003c\/li\u003e\n\u003cli\u003eUSB cable for mount control\u003c\/li\u003e\n\u003cli\u003eMini-USB cable for iPolar\u003c\/li\u003e\n\u003cli\u003eSoft carrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot included:\u003c\/strong\u003e tripod, counterweight shaft, or counterweight.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does the EC version add to the standard HEM27?\u003c\/strong\u003e\u003cbr\u003e\nThe HEM27EC adds a high-precision encoder to the right-ascension axis along with iOptron's Real-Time Periodic Error Correction. The hybrid drive, payload capacity, hand controller, and other major mechanical features remain essentially the same.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does this H274A add over the HEM27EC without iPolar?\u003c\/strong\u003e\u003cbr\u003e\nThis version includes iOptron's factory-installed iPolar electronic polar scope. The encoder and mount mechanics are the same; the difference is the dedicated polar-alignment camera built into the mount.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I image without guiding?\u003c\/strong\u003e\u003cbr\u003e\nPotentially. iOptron says the RA encoder provides enough tracking accuracy that many users may choose to image unguided, particularly at shorter focal lengths. Owner reports include successful multi-minute unguided imaging, but results depend on focal length, pixel scale, payload, polar alignment, and the individual system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eShould I guide the HEM27EC differently from the standard HEM27?\u003c\/strong\u003e\u003cbr\u003e\nUsually. A standard strain-wave mount often benefits from rapid corrections. On the HEM27EC, the encoder is already handling much of the faster RA tracking error. iOptron therefore recommends experimenting with longer guide cadences, often around 5 to 10 seconds, so the guider concentrates on slower errors.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does “Filter R.A. Guiding” do?\u003c\/strong\u003e\u003cbr\u003e\nIt tells the mount to ignore external RA guide commands and let the high-precision encoder handle right ascension while the guider continues correcting declination. “Allow R.A. Guiding” accepts external RA corrections while the encoder continues working between guide pulses.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need to see Polaris to use iPolar?\u003c\/strong\u003e\u003cbr\u003e\nNo. iPolar plate solves the surrounding polar-region star field, so Polaris itself does not have to be visible. Enough surrounding sky must still be visible for the software to identify the field.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow accurately can iPolar align the mount?\u003c\/strong\u003e\u003cbr\u003e\niOptron specifies maximum polar-alignment precision of approximately 30 arcseconds.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes iPolar require a computer?\u003c\/strong\u003e\u003cbr\u003e\nYes. iOptron's official iPolar software runs on 64-bit Windows. The camera connects by USB during alignment. Once polar alignment is complete, the iPolar computer connection is not required simply for normal tracking.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes iPolar replace guiding?\u003c\/strong\u003e\u003cbr\u003e\nNo. iPolar handles polar alignment. The RA encoder improves right-ascension tracking. Guiding corrects whatever tracking errors remain during the exposure. They solve different parts of the imaging problem.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can the HEM27EC carry without a counterweight?\u003c\/strong\u003e\u003cbr\u003e\niOptron rates it for 29.7 lb (13.5 kg) without a counterweight. The rating assumes the payload center of gravity is approximately 200mm from the RA axis, so telescope geometry matters along with total weight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can it carry with a counterweight?\u003c\/strong\u003e\u003cbr\u003e\nWith the optional counterweight system, iOptron publishes a maximum payload of 44 lb (20 kg), subject to the same payload-geometry considerations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it support autoguiding?\u003c\/strong\u003e\u003cbr\u003e\nYes. The HEM27EC includes an ST-4-compatible autoguider port and also supports software-based pulse guiding. The EC version additionally lets you choose whether external RA guide commands are accepted or filtered.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat tripod fits it?\u003c\/strong\u003e\u003cbr\u003e\nThe HEM27EC can mount directly to compatible iOptron CEM26\/GEM28\/HEM27\/HAE29 tripod systems, including the matched LiteRoc and compatible carbon-fiber tripod. A MiniPier can provide additional clearance for longer refractors or deep rear-mounted imaging trains.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM27EC with iPolar is the most complete version of iOptron's remarkably light HEM27 platform because its two upgrades solve two different parts of astrophotography.\u003c\/p\u003e\n\n\u003cp\u003eThe high-precision RA encoder and Real-Time PEC improve the tracking behavior of the strain-wave drive. The built-in iPolar camera makes it easier to put the mount's RA axis accurately on the celestial pole before the exposure begins.\u003c\/p\u003e\n\n\u003cp\u003eUnderneath both is still the feature that made the HEM27 interesting in the first place: 29.7 pounds of counterweight-free capacity in a mount head weighing just 8.15 pounds.\u003c\/p\u003e\n\n\u003cp\u003eAt forgiving image scales, the combination can make unguided imaging practical. At longer focal lengths, the encoder can allow a more relaxed guiding strategy while iPolar provides the accurate alignment that helps keep declination drift under control.\u003c\/p\u003e\n\n\u003cp\u003eIf you want the HEM27's portability, the EC model's improved RA tracking, and a dedicated polar-alignment system already built into the mount, this is the version that puts all three together.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

That is where the ability to operate with a heavily unbalanced load eliminates the need for the traditional counterweight system and gives the HEM44 its unusually high payload-to-mount-weight ratio.\u003c\/p\u003e\n\n\u003cp\u003eDeclination uses a different solution: a belt-driven, spring-loaded worm system that iOptron describes as backlash-free. Because a telescope can be moved forward or backward in the saddle, DEC can be balanced conventionally without needing another strain-wave gear.\u003c\/p\u003e\n\n\u003cp\u003eThat combination also gives iOptron room for something that is particularly useful on a serious imaging rig: stationary through-mount cable management.\u003c\/p\u003e\n\n\u003cp\u003eThe result is less about using strain-wave gearing everywhere and more about using it where its advantages matter most.\u003c\/p\u003e\n\n\u003ch3\u003e44 Pounds Without Counterweights\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM44's defining number is 44 pounds.\u003c\/p\u003e\n\n\u003cp\u003eThat is enough capacity for imaging systems that begin pushing beyond the natural territory of the smaller HEM27: larger refractors, compact SCTs, RCs, astrographs, and dual-scope configurations with cameras, focusers, filter wheels, guiders, and other accessories attached.\u003c\/p\u003e\n\n\u003cp\u003eThere is an important qualification to the payload rating. iOptron bases it on the payload's center of gravity being approximately 200mm from the RA rotation axis, or an optical tube around 220mm in diameter.\u003c\/p\u003e\n\n\u003cp\u003eA compact 35-pound SCT and a long 35-pound refractor therefore do not place the same mechanical load on the mount. Tube length, diameter, rear-mounted imaging equipment, and wind exposure all matter along with total weight.\u003c\/p\u003e\n\n\u003cp\u003eThe optional counterweight system raises the published payload to 55 lb, but it can also be useful below that limit when telescope geometry makes a particular load more demanding.\u003c\/p\u003e\n\n\u003cp\u003eCounterweight-free is a capability, not a requirement.\u003c\/p\u003e\n\n\u003ch3\u003eGuiding the Standard HEM44\u003c\/h3\u003e\n\n\u003cp\u003eThe standard HEM44 does not have the high-precision RA encoder found in the HEM44EC.\u003c\/p\u003e\n\n\u003cp\u003eiOptron also deliberately does not publish a fixed periodic-error specification for the non-encoder HEM44. The company notes that strain-wave periodic error varies with payload, telescope position, and imbalance, making a single factory number less meaningful than it would be on a traditional worm-drive mount.\u003c\/p\u003e\n\n\u003cp\u003eFor long-exposure deep-sky imaging, plan on guiding.\u003c\/p\u003e\n\n\u003cp\u003eStrain-wave drives can change tracking rate relatively quickly through portions of the gear cycle, so the standard HEM44 often responds well to relatively short guide exposures. iOptron's own guidance suggests guide exposures around 0.5 second as a starting point for a non-encoder strain-wave system, although the best setting depends on the guider, telescope, seeing, and image scale.\u003c\/p\u003e\n\n\u003cp\u003ePHD2's Predictive PEC algorithm can also be useful because the strain-wave error has a repeating 270-second gear period. Give the guiding system time to learn the behavior of the mount before judging the final result.\u003c\/p\u003e\n\n\u003cp\u003eThe number on the guide graph is not the final goal. Look at the actual stars in the exposures and tune from there.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eHEM44 owners on Cloudy Nights provide useful context for both the mount's payload and its guiding behavior.\u003c\/p\u003e\n\n\u003cp\u003eOne owner using the standard HEM44 for a dual imaging rig measured unusually large raw periodic error — close to 90 arcseconds peak-to-peak in his particular setup. That number sounds dramatic, but he also reported that PHD2's Predictive PEC learned the curve quickly and that the system could guide around 0.7 arcsecond RMS when seeing supported it.\u003c\/p\u003e\n\n\u003cp\u003eThat should not be treated as the HEM44's periodic-error specification. iOptron specifically declines to publish one for the standard mount because strain-wave error varies with loading and position. What the owner's experience does show is why relatively quick guiding and a predictive algorithm can matter on the non-encoder version.\u003c\/p\u003e\n\n\u003cp\u003eAnother owner provides a useful payload comparison. His roughly 30-pound 130mm triplet imaging system was more than he was happy with on the smaller HEM27, where he saw RA streaking. Moving the same kind of workload to the HEM44 solved the problem for him.\u003c\/p\u003e\n\n\u003cp\u003eThat is probably the clearest reason to move from the 27 to the 44. It isn't simply another 14 pounds printed on a payload specification. The larger platform gives a long or heavily accessorized telescope more mechanical room to work.\u003c\/p\u003e\n\n\u003cp\u003eThere are also owner reports of heavier configurations benefiting from the optional counterweight even when technically below the 44-pound counterweight-free limit. Again, counterweight-free means you can operate without one; it does not mean every telescope performs best without one.\u003c\/p\u003e\n\n\u003ch3\u003ePower-Down Memory\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM44 includes a particularly useful feature for a mount carrying a large imaging system: power-down position memory.\u003c\/p\u003e\n\n\u003cp\u003eIf power is interrupted, the mount retains its RA and DEC positions. Once power returns, you can select the same target again and the mount can resume tracking without going through the entire setup process from the beginning.\u003c\/p\u003e\n\n\u003cp\u003eThat does not mean every imaging application or camera sequence automatically resumes after a power failure, but the mount itself does not forget where it was simply because power disappeared.\u003c\/p\u003e\n\n\u003cp\u003eThe electronic friction brake works alongside that feature by stopping the mount rather than allowing an unbalanced payload to swing freely when power is lost.\u003c\/p\u003e\n\n\u003ch3\u003eNo GPS — Set Time and Site Correctly\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM44 does not contain its own GPS receiver.\u003c\/p\u003e\n\n\u003cp\u003eThe GoTo system therefore needs accurate date, time, UTC offset, longitude, latitude, and hemisphere information. You can enter those manually through the hand controller or import location information from a smartphone using iOptron Commander Lite.\u003c\/p\u003e\n\n\u003cp\u003eThe mount also needs to begin from a correctly registered Zero Position. The built-in zero-position search makes that straightforward, and Sync to Target can improve local GoTo accuracy after you center an object.\u003c\/p\u003e\n\n\u003cp\u003eIf the mount ever appears to be pointing consistently into the wrong part of the sky, check the time, UTC offset, longitude East\/West setting, hemisphere, and Zero Position before assuming there is a mechanical problem.\u003c\/p\u003e\n\n\u003ch3\u003eThis Version Does Not Include iPolar\u003c\/h3\u003e\n\n\u003cp\u003eThe H442 is the standard HEM44 without iPolar.

For a retail page, it is safer to treat ASIAIR as third-party integration rather than promise a particular driver selection indefinitely.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat tripod fits it?\u003c\/strong\u003e\u003cbr\u003e\nThe HEM44 mounts directly to compatible iOptron CEM40\/GEM45\/HAE43\/HEM44 tripod systems, including the matched LiteRoc tripod and compatible carbon-fiber tripod. It can also be used with iOptron's Tri-Pier. A compatible MiniPier provides additional clearance for long refractors and deep rear-mounted imaging trains.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat power does it require?\u003c\/strong\u003e\u003cbr\u003e\nThe mount uses 12V DC at up to 5A through a 5.5\/2.5mm center-positive input. The included 100–240V AC adapter is intended for indoor use.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe HEM44 fills the gap between a small strain-wave travel mount and the much heavier equatorial systems traditionally used for larger imaging rigs.\u003c\/p\u003e\n\n\u003cp\u003eIts 13.65-pound head carries up to 44 pounds without a counterweight, while the hybrid design combines a compact strain-wave RA drive with a backlash-free worm-and-belt DEC system and useful through-mount cable management.\u003c\/p\u003e\n\n\u003cp\u003eThis standard H442 version makes the most sense for an imager who already has a polar-alignment routine and plans to guide. You avoid paying for iPolar or the EC encoder while keeping the same basic payload capacity, cable management, electronic brake, power-down memory, GoTo system, and portable form factor.\u003c\/p\u003e\n\n\u003cp\u003eIf your telescope has outgrown the HEM27 but your enthusiasm for hauling a traditional heavy equatorial mount has not grown with it, the HEM44 is the logical next step.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

Add the optional counterweight system and the published capacity rises to 55 lb (25 kg). That gives the HEM44EC room for larger refractors, SCTs, astrographs, and heavily equipped imaging systems without returning to the weight and counterweight burden of a traditional German equatorial mount.\u003c\/p\u003e\n\n\u003cp\u003eThe EC version adds a high-precision encoder to the right-ascension axis. Working with iOptron's Real-Time Periodic Error Correction, the encoder continuously measures RA motion and corrects much of the strain-wave drive's tracking error internally. At shorter focal lengths that can make unguided imaging practical.

Because the encoder is already handling much of the fast RA error, iOptron recommends experimenting with much longer guide exposures — typically in the 5–10 second range — to correct slower errors such as polar misalignment, atmospheric refraction, and flexure.\u003c\/p\u003e\n\n\u003cp\u003eThat is especially useful with an off-axis guider on an SCT or longer refractor, where faint guide stars may become dramatically easier to work with once the camera has several seconds to collect signal.\u003c\/p\u003e\n\n\u003cp\u003eThe correct cadence still depends on the telescope, guide camera, seeing, image scale, and the rest of the system.

The high-precision encoder improves the RA tracking behavior that normally makes strain-wave mounts demanding to guide. The built-in iPolar gives you a dedicated way to establish the accurate polar alignment that the encoder itself cannot provide.\u003c\/p\u003e\n\n\u003cp\u003eAt shorter focal lengths, that combination can make unguided imaging practical. At the longer focal lengths the HEM44 is capable of carrying, the greater advantage may be the ability to let the encoder handle the faster RA error while an external guider works at a slower cadence.\u003c\/p\u003e\n\n\u003cp\u003eIf you want the HEM44's payload capacity, the EC encoder, and a dedicated polar-alignment system already built into the mount, the H444A puts all three together.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

That gives the imaging system a smoother tracking platform to begin with.\u003c\/p\u003e\n\n\u003cp\u003eiOptron says the resulting accuracy is sufficient that many users may choose to image without guiding. Whether that makes sense for your particular system still depends on focal length, pixel scale, exposure time, polar alignment, and how demanding you are about star shape.\u003c\/p\u003e\n\n\u003cp\u003eWith a shorter or more forgiving image scale, encoder-assisted unguided imaging may be practical. At longer focal lengths and finer image scales, guiding can still provide the additional correction required for consistently good long exposures.\u003c\/p\u003e\n\n\u003cp\u003eThe important point is not that the encoder makes guiding obsolete. It is that the RA axis is already correcting itself before the guider enters the picture.\u003c\/p\u003e\n\n\u003ch3\u003e44 Pounds Without Counterweights\u003c\/h3\u003e\n\n\u003cp\u003eThe encoder gets much of the attention on the EC model, but the basic HAE43 platform remains impressive on its own.\u003c\/p\u003e\n\n\u003cp\u003eA 12.6 lb mount head is rated to carry 44 lb without counterweights. That leaves room for a telescope, cooled camera, filter wheel, electronic focuser, guide system, rotator, and the other equipment that begins accumulating around a serious imaging rig.\u003c\/p\u003e\n\n\u003cp\u003eAdd the optional counterweight system and the rated capacity increases to 55 lb.\u003c\/p\u003e\n\n\u003cp\u003eThere is an important qualification to those numbers. iOptron bases its payload rating on the center of gravity being approximately 200mm from the RA rotation axis. A compact 35-pound SCT or astrograph and a long 35-pound refractor do not place the same load on the drive.\u003c\/p\u003e\n\n\u003cp\u003eThat makes telescope geometry just as important as scale weight. Compact astrographs, SCTs, and reasonably sized refractors play particularly well to the HAE43C-EC's strengths. As the tube becomes longer and the moment arm increases, leaving additional margin below the published payload becomes increasingly sensible.\u003c\/p\u003e\n\n\u003cp\u003eThe optional counterweight is there when a particular configuration benefits from one. Counterweight-free is a capability, not a rule.\u003c\/p\u003e\n\n\u003ch3\u003eGuiding an Encoder Mount\u003c\/h3\u003e\n\n\u003cp\u003eThe EC version can also change the way you approach guiding.\u003c\/p\u003e\n\n\u003cp\u003eOn a non-encoder strain-wave mount, relatively frequent guide corrections are commonly used because the guider has to follow the drive's tracking error directly. The HAE43C-EC is already correcting RA internally through the encoder and Real-Time PEC.\u003c\/p\u003e\n\n\u003cp\u003eThat means there is no reason to assume the fastest possible guide cadence is automatically the best one.\u003c\/p\u003e\n\n\u003cp\u003eSeeing conditions, guide-camera sensitivity, focal length, image scale, DEC behavior, guiding software, and the telescope itself all influence the optimum settings. Some imaging systems may work well with slower RA corrections that allow the encoder to do more of the work. Others may respond better to a somewhat faster cadence.\u003c\/p\u003e\n\n\u003cp\u003eThe best guide setting is the one that produces the best actual images. Round stars and consistent FWHM in your subframes matter more than chasing the smallest possible RMS number on a graph.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eExperience from HAE43EC and HAE43C-EC owners on Cloudy Nights provides some useful perspective on what the encoder can realistically do.\u003c\/p\u003e\n\n\u003cp\u003eOwners generally report that the encoder substantially reduces the raw RA tracking error of the strain-wave drive. One owner using both HAE29EC and HAE43EC mounts described the encoder as largely invisible in normal operation after initial calibration and reported excellent results with the HAE43EC carrying a 10-inch RC.\u003c\/p\u003e\n\n\u003cp\u003eThat same owner made an important point: the encoder tames the strain-wave periodic error rather than making it disappear completely. He continued to guide and favored a slower guiding cadence than he would use with a non-encoder harmonic mount.\u003c\/p\u003e\n\n\u003cp\u003eOther HAE43C-EC users have found that their systems respond better to somewhat quicker corrections, particularly while working through DEC backlash, guiding configuration, and longer focal lengths. That variation is exactly why copying another owner's guide settings rarely gives the whole answer.\u003c\/p\u003e\n\n\u003cp\u003eThere are also examples of owners initially struggling with guiding and later getting much better performance after working through PHD2 settings, DEC behavior, telescope position, and the rigidity of the pier or tripod. The encoder improves the RA tracking platform, but the telescope, support, guide system, software, seeing, and setup still matter.\u003c\/p\u003e\n\n\u003cp\u003eThe useful takeaway from the community is straightforward: buy the EC version for better RA tracking, not because you expect every imaging system to become permanently unguided. Let the encoder do its job, add guiding when your image scale benefits from it, and judge the mount by the stars in the finished exposures.\u003c\/p\u003e\n\n\u003ch3\u003eControl It the Way You Want\u003c\/h3\u003e\n\n\u003cp\u003eThe HAE43C-EC has its main control electronics built into the mount, so a hand controller is no longer required simply to operate it.\u003c\/p\u003e\n\n\u003cp\u003eConnect directly through USB-C for a software-driven imaging setup. Windows users can work through iOptron Commander and ASCOM, while compatible INDI software provides control options on other platforms.\u003c\/p\u003e\n\n\u003cp\u003eBuilt-in Wi-Fi also allows wireless operation from compatible smartphones and tablets using iOptron Commander Lite or applications such as SkySafari.\u003c\/p\u003e\n\n\u003cp\u003eIf you prefer physical controls at the telescope, iOptron's optional 8411 Go2Nova OLED handset provides standalone GoTo operation.\u003c\/p\u003e\n\n\u003cp\u003eThat gives the HAE43C-EC considerable flexibility. It can sit underneath a fully automated imaging computer one night and operate as a visual GoTo mount with a handset the next.\u003c\/p\u003e\n\n\u003ch3\u003eEQ for Imaging, Alt-Az for Visual\u003c\/h3\u003e\n\n\u003cp\u003eThe HAE43C-EC can operate in either equatorial or Alt-Az mode.\u003c\/p\u003e\n\n\u003cp\u003eIn equatorial mode, polar alignment provides the geometry required for long-exposure astrophotography. The encoder, Real-Time PEC, and optional guiding then handle the tracking side of the system.\u003c\/p\u003e\n\n\u003cp\u003eSwitch to Alt-Az mode and the same mount becomes a high-capacity GoTo platform for visual observing without requiring a normal polar-alignment routine.\u003c\/p\u003e\n\n\u003cp\u003eThat is particularly useful on a mount with this much capacity.

That makes it a natural match for portable refractors, SCTs, large binoculars, and other visual instruments that would normally sit on a much heavier conventional GoTo mount.\u003c\/p\u003e\n\n\u003cp\u003eBoth altitude and azimuth use strain-wave gearing with a 480:1 reduction ratio. The high torque of those drives is what allows the HAZ31 to operate intentionally unbalanced, so there is no counterweight to carry, install, or reposition when you change eyepieces. The result is a compact Alt-Az mount designed first and foremost for visual observing, outreach, and situations where fast setup matters.\u003c\/p\u003e\n\n\u003cp\u003eSetup is straightforward. Level the mount, attach the telescope, turn it on, and the built-in Assistant Alignment Wizard finds the mount's zero position, acquires GPS information, and takes you to a bright star for calibration. After that, the Go2Nova 8409 hand controller gives you access to a database of roughly 212,000 objects, or you can control the mount from compatible software over USB or Wi-Fi.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e31 lb payload without a counterweight.\u003c\/strong\u003e iOptron rates the HAZ31 for 14 kg (31 lb) while the mount head itself weighs only 8.2 lb.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eStrain-wave gearing on both axes.\u003c\/strong\u003e Altitude and azimuth each use a 480:1 strain-wave drive, giving the mount the torque needed to operate with an intentionally unbalanced telescope.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAlt-Az GoTo operation.\u003c\/strong\u003e No polar alignment and no counterweight balancing are required for normal visual use.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in GPS.\u003c\/strong\u003e The mount can acquire its location and time information automatically during setup.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAssistant Alignment Wizard.\u003c\/strong\u003e The HAZ31 can locate its zero position, acquire GPS data, and move to a bright star for final calibration.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eGo2Nova 8409 hand controller.\u003c\/strong\u003e Provides a database of approximately 212,000 objects and standalone operation without requiring a phone or computer.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Wi-Fi through the hand controller.\u003c\/strong\u003e Supports wireless control from compatible applications such as iOptron Commander Lite and SkySafari.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eUSB computer control.\u003c\/strong\u003e Windows users can operate the mount through iOptron Commander and ASCOM, with third-party INDI support available on other platforms.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eVixen and Losmandy-D saddle.\u003c\/strong\u003e The convertible saddle supports both common dovetail formats.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eDedicated binocular configuration.\u003c\/strong\u003e The saddle can be repositioned on top of the mount for large-binocular use and better zenith clearance.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eMaximum slew speed of 8° per second.\u003c\/strong\u003e Fast enough to move across large portions of the sky quickly during an observing session.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eSatellite tracking capable.\u003c\/strong\u003e The HAZ31 can be used with iOptron's Ultimate Orbit Tracker or compatible third-party software for moving-object tracking.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eElectronic friction brakes on both axes.\u003c\/strong\u003e Designed to stop mount movement safely during a planned or unexpected power interruption.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in zero-position sensing.\u003c\/strong\u003e Magnetic and altitude sensors help the mount establish a repeatable starting position.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption.\u003c\/strong\u003e iOptron specifies approximately 0.6A while tracking and 1A during GoTo operation.\u003c\/li\u003e\n\n\u003cli\u003e\u003cstrong\u003eAll-metal CNC-machined construction.\u003c\/strong\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cstrong\u003eCarrying case included.\u003c\/strong\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cstrong\u003eTwo-year limited warranty.\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eLevel, Turn It On, and Go\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ31 avoids most of the setup routine associated with an equatorial mount.\u003c\/p\u003e\n\n\u003cp\u003eThere is no polar axis to align and no counterweight system to balance. What does matter is getting the mount reasonably level and making sure the tripod is stable before beginning the alignment procedure. Because the HAZ31 operates with an intentionally unbalanced load, a secure support is especially important.\u003c\/p\u003e\n\n\u003cp\u003eWhen you turn the mount on, the Assistant Alignment Wizard can rotate the mount in azimuth to establish its reference direction, locate the altitude zero position, acquire GPS information, and then slew to a bright star.\u003c\/p\u003e\n\n\u003cp\u003eCenter that star as instructed and the mount is ready for GoTo operation.\u003c\/p\u003e\n\n\u003cp\u003eIf you move to another part of the sky and want to improve local pointing accuracy, the hand controller's Sync to Target function lets you center a known object and refine the model around that area.\u003c\/p\u003e\n\n\u003ch3\u003eA Mount Made for Visual Observing\u003c\/h3\u003e\n\n\u003cp\u003eThe 31 lb payload rating puts the HAZ31 in an unusual place. It is light enough to carry outside with one hand, yet it can support telescopes that normally end up on substantially heavier mounts.\u003c\/p\u003e\n\n\u003cp\u003eA 4-inch or moderate-size 5-inch refractor can make a very capable lunar, planetary, double-star, and deep-sky visual system. A compact 8-inch SCT gives you significantly more aperture without making the mount itself difficult to transport. Smaller telescopes become exceptionally easy grab-and-go systems.\u003c\/p\u003e\n\n\u003cp\u003eThe payload number is not the whole story, however. iOptron's 31 lb rating assumes the payload's center of gravity is approximately 200mm from the mount's rotation axis, or an optical tube around 220mm in diameter.\u003c\/p\u003e\n\n\u003cp\u003eA compact 20 lb SCT and a very long 20 lb refractor do not put the same load on the mount. Tube length, center of gravity, accessories, and wind exposure all matter along with the number on the scale.\u003c\/p\u003e\n\n\u003cp\u003eThat is particularly important with longer refractors. The mount may have plenty of weight capacity while the telescope's length creates clearance or vibration considerations that a shorter tube does not.\u003c\/p\u003e\n\n\u003ch3\u003eTwo Saddle Positions for Two Different Jobs\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ31's saddle can be configured differently depending on what you are mounting.\u003c\/p\u003e\n\n\u003cp\u003eFor a conventional telescope, iOptron's normal configuration places the saddle on the \u003cstrong\u003eside\u003c\/strong\u003e of the mount. The telescope then rides beside the altitude axis in the familiar Alt-Az arrangement.\u003c\/p\u003e\n\n\u003cp\u003eFor large astronomical binoculars, the saddle can be repositioned to the \u003cstrong\u003etop\u003c\/strong\u003e of the mounting plate. That places the binocular assembly above the mount and gives it a much more natural path toward the zenith.\u003c\/p\u003e\n\n\u003cp\u003eThe same saddle can also be configured for either Vixen-style or Losmandy-D dovetail bars.\u003c\/p\u003e\n\n\u003cp\u003eThat binocular option is one of the HAZ31's more interesting features. Large 70mm, 82mm, 100mm, and similar binocular telescopes benefit tremendously from tracking because high-altitude targets no longer require continually repositioning the entire binocular assembly while you observe.\u003c\/p\u003e\n\n\u003ch3\u003eUnder the Night Sky\u003c\/h3\u003e\n\n\u003cp\u003eFor visual astronomy, the HAZ31's greatest benefit is not simply GoTo. It is what happens after the GoTo finishes.\u003c\/p\u003e\n\n\u003cp\u003ePut Jupiter in the field at high power and the mount keeps it there while you wait for moments of steadier seeing. Move to Saturn and you can spend time studying the rings instead of continually nudging the telescope. On the Moon, you can work your way along the terminator while the same crater field remains centered.\u003c\/p\u003e\n\n\u003cp\u003eThat becomes even more useful with double stars. Rather than star hopping to one pair, observing it, and starting over for the next, the 8409 hand controller can take you from one object to another while the tracking lets you concentrate on the split.\u003c\/p\u003e\n\n\u003cp\u003eWith a larger-aperture SCT, globular clusters, planetary nebulae, galaxies, and smaller deep-sky objects become natural targets. With a wide-field refractor, open clusters and large star fields take over. And with large binoculars mounted on top, the HAZ31 becomes a particularly comfortable way to work through Milky Way clusters and nebulae without constantly moving a heavy binocular setup by hand.\u003c\/p\u003e\n\n\u003ch3\u003eHow Accurate Is the Tracking?\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ31 is designed for visual tracking rather than precision equatorial imaging, so the useful question is not whether the guide graph measures a particular RMS value. It is whether an object stays comfortably in the eyepiece while you observe it.\u003c\/p\u003e\n\n\u003cp\u003eOwner experience on Cloudy Nights has generally been encouraging in that respect. One observer using 120mm binoculars reported being able to leave the mount unattended and return much later with the target still visible. Other owners have used 4- and 5-inch refractors and 8-inch Newtonians successfully for visual GoTo and tracking.\u003c\/p\u003e\n\n\u003cp\u003eGoTo accuracy can vary more across widely separated parts of the sky. A useful habit is to use Sync to Target after moving to a distant region if the object is not as well centered as you would like. Once synchronized in that area, nearby GoTo moves can become noticeably more accurate.\u003c\/p\u003e\n\n\u003ch3\u003eWhat About Astrophotography?\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ31 is an Alt-Az mount, and that should shape your expectations before you buy it.\u003c\/p\u003e\n\n\u003cp\u003eIt is very well suited to visual observing, and it can also be useful for lunar and planetary imaging, where cameras record large numbers of very short exposures or video frames. Short-exposure electronic-assisted observing and live stacking can also be practical.\u003c\/p\u003e\n\n\u003cp\u003eIt is not designed as a conventional long-exposure deep-sky imaging mount. Because an Alt-Az mount tracks the sky in altitude and azimuth rather than rotating around the celestial pole, the orientation of the field changes over time. That field rotation becomes increasingly visible as individual exposures get longer.\u003c\/p\u003e\n\n\u003cp\u003eFor traditional multi-minute guided exposures of galaxies and nebulae, an equatorial mount is the appropriate tool.\u003c\/p\u003e\n\n\u003ch3\u003ePower in the Field\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ31 operates from 12V DC and iOptron specifies a 5.5\/2.1mm center-positive power connection.\u003c\/p\u003e\n\n\u003cp\u003eThe included 100–240V AC adapter provides 12V\/5A power for indoor use. At a dark site, you'll need a suitable external 12V supply or battery.\u003c\/p\u003e\n\n\u003cp\u003eThe mount itself is relatively easy on power. iOptron specifies approximately 0.6A while tracking and about 1A during GoTo operation, although the field power source should still be capable of supplying the mount's required voltage reliably.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eHAZ31 owners repeatedly come back to the same strengths: low weight, easy transport, quiet operation, and surprisingly capable visual tracking.\u003c\/p\u003e\n\n\u003cp\u003eOne owner uses the HAZ31 with 120mm binoculars and reported that after the initial synchronization, GoTo accuracy was particularly good within the same region of the sky and tracking was good enough that targets remained in view during extended observing periods.\u003c\/p\u003e\n\n\u003cp\u003eAnother owner has used both a 125mm ED refractor and a 24 lb 8-inch f\/4 Newtonian on the mount. The HAZ31 moved both successfully, although the lightweight carbon-fiber tripod took somewhat longer to settle than a much heavier steel tripod.\u003c\/p\u003e\n\n\u003cp\u003eThat is a useful reminder of something true for any lightweight mount: payload capacity and vibration performance are not the same specification. A very light tripod makes the system wonderfully portable; a heavier support can improve settling behavior with a long or demanding telescope.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eiOptron HAZ31 strain-wave Alt-Az GoTo mount head\u003c\/li\u003e\n\u003cli\u003eConvertible Vixen \/ Losmandy-D dovetail saddle\u003c\/li\u003e\n\u003cli\u003eGo2Nova 8409 V2 hand controller with built-in Wi-Fi\u003c\/li\u003e\n\u003cli\u003e6P6C coiled hand-controller cable\u003c\/li\u003e\n\u003cli\u003eUSB 2.0 cable for computer control and firmware updates\u003c\/li\u003e\n\u003cli\u003e100–240V AC to 12V\/5A DC power adapter for indoor use\u003c\/li\u003e\n\u003cli\u003eCarrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot included:\u003c\/strong\u003e tripod, MiniPier, or field battery.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much does the HAZ31 weigh?\u003c\/strong\u003e\u003cbr\u003e\nThe mount head weighs 8.2 lb (3.7 kg) with its dovetail saddle installed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can the HAZ31 carry?\u003c\/strong\u003e\u003cbr\u003e\niOptron rates it for 31 lb (14 kg). That rating assumes the payload center of gravity is about 200mm from the rotation axis, so telescope length and geometry matter in addition to actual weight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the HAZ31 need a counterweight?\u003c\/strong\u003e\u003cbr\u003e\nNo. It is designed to operate without a counterweight or counterweight shaft.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it need polar alignment?\u003c\/strong\u003e\u003cbr\u003e\nNo. The HAZ31 is an Alt-Az mount rather than an equatorial mount, so there is no polar axis to align.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it have GPS?\u003c\/strong\u003e\u003cbr\u003e\nYes.

As always, include the diagonal, eyepiece, finder, dew equipment, and other accessories when calculating the total load.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan it carry a 5-inch refractor?\u003c\/strong\u003e\u003cbr\u003e\nMany 5-inch refractor systems can fall within the 31 lb payload rating, but a long refractor places more leverage on the mount than a compact telescope of the same weight. Tube length, center of gravity, tripod stability, and zenith clearance should all be considered.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the HAZ31 suitable for large binoculars?\u003c\/strong\u003e\u003cbr\u003e\nYes. Large-binocular mounting is an intended feature of the design. The saddle can be repositioned to the top of the mount to provide a more suitable geometry for binocular observing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan the HAZ31 do astrophotography?\u003c\/strong\u003e\u003cbr\u003e\nIt can be useful for lunar and planetary imaging and for short-exposure EAA or live stacking. It is not intended as a traditional long-exposure deep-sky imaging mount because Alt-Az tracking produces field rotation over time.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHAZ31 or HAZ46?\u003c\/strong\u003e\u003cbr\u003e\nThe HAZ31 emphasizes portability with an 8.2 lb mount head and 31 lb payload rating. The HAZ46 is the larger member of the family for heavier or more demanding telescope systems. Choose based on the complete telescope's weight, length, center of gravity, and the support system you intend to use rather than aperture alone.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat tripod does the HAZ31 use?\u003c\/strong\u003e\u003cbr\u003e\niOptron lists the 8061A Carbon Fiber Tripod as a current matched option.

A 5-inch refractor, a 180mm Maksutov, a larger SCT, or a binocular telescope may be perfectly manageable on its own, but add a conventional GoTo mount, counterweight shaft, weights, and a heavy tripod and suddenly a quick observing session becomes a small moving project.\u003c\/p\u003e\n\n\u003cp\u003eThe iOptron HAZ46 is built to change that equation. The mount head weighs just 12.3 lb (5.6 kg) with its saddle installed, yet iOptron rates it for a 44 lb (20 kg) payload without a counterweight or counterweight shaft. Both axes use high-torque strain-wave gearing, allowing the mount to carry substantial telescopes while operating intentionally unbalanced.\u003c\/p\u003e\n\n\u003cp\u003eThe HAZ46 is an Alt-Az mount designed first for visual observing, outreach, large binoculars, lunar and planetary work, and other applications where fast setup matters more than long-exposure equatorial imaging. Built-in GPS, automatic zero-position sensing, GoTo, tracking, and an internal rechargeable battery mean there is remarkably little to assemble before you start observing.\u003c\/p\u003e\n\n\u003cp\u003eThat internal battery is one of the differences between the HAZ46 and the smaller HAZ31. Charge the mount before you leave home and there is no mount-power cable running down to a battery on the ground while the telescope turns through the night. Combined with a 12.3 lb mount head and no counterweights, it makes the HAZ46 unusually easy to move for something capable of carrying a serious visual telescope.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e44 lb payload without a counterweight.\u003c\/strong\u003e iOptron rates the HAZ46 for 20 kg (44 lb) of payload while the mount head itself weighs only 12.3 lb.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eStrain-wave gearing on both axes.\u003c\/strong\u003e Altitude and azimuth each use a 640:1 strain-wave drive, providing the torque needed to operate without conventional balancing.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in rechargeable battery.\u003c\/strong\u003e An internal 11.1V, 4.4Ah lithium-ion battery lets the mount operate without a separate field battery and power cable under normal use.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in GPS.\u003c\/strong\u003e The mount can automatically acquire location information during setup.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAssistant Alignment Wizard.\u003c\/strong\u003e Automatic zero-position sensing, GPS acquisition, and bright-star calibration simplify setup.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eGo2Nova 8409 hand controller.\u003c\/strong\u003e Includes a database of approximately 212,000 objects and can operate the mount without a phone or computer.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eWi-Fi through the hand controller.\u003c\/strong\u003e Compatible applications such as iOptron Commander Lite and SkySafari can control the mount wirelessly.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eUSB computer control.\u003c\/strong\u003e Supports iOptron Commander and ASCOM under Windows, with third-party INDI support available on other platforms.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eVixen \/ Losmandy-D convertible saddle.\u003c\/strong\u003e Supports both common dovetail formats.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eDedicated binocular mounting position.\u003c\/strong\u003e The saddle can be moved from its normal side-mounted telescope position to an up-mounted position for large binoculars.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e6° per second maximum slew speed.\u003c\/strong\u003e Fast enough to move efficiently between widely separated targets.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eSatellite tracking capable.\u003c\/strong\u003e The HAZ46 can work with iOptron's Ultimate Orbit Tracker or compatible third-party software.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eElectronic friction brakes on both axes.\u003c\/strong\u003e Designed to stop movement safely during a planned or unexpected interruption in power.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in zero-position sensing.\u003c\/strong\u003e Internal sensors let the mount establish a repeatable reference position during setup.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption.\u003c\/strong\u003e iOptron specifies approximately 0.7A while tracking and 1.2A during GoTo operation.\u003c\/li\u003e\n\n\u003cli\u003e\u003cstrong\u003eAll-metal CNC-machined construction.\u003c\/strong\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cstrong\u003eCarrying case included.\u003c\/strong\u003e\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eTwo-year limited warranty.\u003c\/strong\u003e The internal rechargeable battery carries a 90-day warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e44 Pounds Without the Counterweights\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46's defining specification is not simply its 44 lb payload. It is carrying that payload on a 12.3 lb mount head without a counterweight system.\u003c\/p\u003e\n\n\u003cp\u003eThat opens the door to telescopes that normally turn a portable visual setup into something considerably more involved. A 5-inch refractor, 180mm Maksutov, 8-inch SCT, compact Newtonian, or large binocular telescope can all fall comfortably within the HAZ46's intended range when the complete system and its geometry are appropriate.\u003c\/p\u003e\n\n\u003cp\u003eThe geometry part matters. iOptron's 44 lb rating assumes the payload's center of gravity is approximately 200mm from the mount's rotation axis, or an optical tube around 220mm in diameter.\u003c\/p\u003e\n\n\u003cp\u003eA compact 25 lb Maksutov and a long 25 lb refractor do not place the same mechanical load on the mount. Length, diameter, accessory placement, center of gravity, and wind exposure all matter along with actual weight.\u003c\/p\u003e\n\n\u003cp\u003eThat is why the HAZ46 should be thought of as a high-capacity portable mount rather than simply a scale with a 44 lb limit.\u003c\/p\u003e\n\n\u003ch3\u003eThe Built-In Battery Changes the Setup\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 contains an 11.1V, 4.4Ah rechargeable lithium-ion battery.\u003c\/p\u003e\n\n\u003cp\u003eFor visual observing, that is more useful than it may sound. There is no power cord hanging from a rotating Alt-Az mount, no field battery sitting where someone can trip over it, and one less piece of equipment to carry from the car.\u003c\/p\u003e\n\n\u003cp\u003eThe included charger accepts 100–240V AC and supplies 12.6V DC at 2A. The mount's DC input can also power the HAZ46 or charge its internal battery.\u003c\/p\u003e\n\n\u003cp\u003eiOptron specifies approximately 0.7A power consumption while tracking and about 1.2A during GoTo operation. Actual battery runtime will vary with temperature, slewing, payload, battery condition, and use.\u003c\/p\u003e\n\n\u003cp\u003eFor longer sessions, an appropriate external supply can still be used through the mount's DC input.\u003c\/p\u003e\n\n\u003ch3\u003eLevel It and Let the Mount Find Itself\u003c\/h3\u003e\n\n\u003cp\u003eThere is no polar alignment because the HAZ46 is an Alt-Az mount.\u003c\/p\u003e\n\n\u003cp\u003eSetup instead begins with a stable, reasonably level tripod. After the telescope and accessories are secured, turn the mount on and start the Assistant Alignment Wizard.\u003c\/p\u003e\n\n\u003cp\u003eThe HAZ46 uses internal sensors and GPS to establish its reference position. During the automatic process, the mount rotates through 360° in azimuth, finds the altitude zero position with the telescope pointed toward the zenith, acquires GPS information, and then slews to a bright star for final calibration.\u003c\/p\u003e\n\n\u003cp\u003eBecause the mount moves through a full azimuth rotation during that process, make sure the telescope, diagonal, cables, and accessories have enough clearance before starting the wizard.\u003c\/p\u003e\n\n\u003cp\u003eCenter the calibration star as instructed and the mount is ready for GoTo and tracking. If you later move into another part of the sky and want to refine local pointing accuracy, the hand controller's Sync to Target function can recalibrate the mount around a known object.\u003c\/p\u003e\n\n\u003ch3\u003eTwo Saddle Positions, Two Different Uses\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 uses the same multi-position saddle idea as the other HAZ mounts.\u003c\/p\u003e\n\n\u003cp\u003eFor a conventional telescope, iOptron's normal configuration puts the dovetail saddle on the \u003cstrong\u003eside\u003c\/strong\u003e of the altitude assembly. Refractors, Maksutovs, SCTs, and Newtonians ride beside the mount in the familiar Alt-Az arrangement.\u003c\/p\u003e\n\n\u003cp\u003eFor large binoculars, the saddle can be moved to the \u003cstrong\u003etop\u003c\/strong\u003e of the adapting plate. The binocular assembly then sits above the altitude axis, giving it a much more useful geometry for comfortable two-eyed observing and access near the zenith.\u003c\/p\u003e\n\n\u003cp\u003eThe saddle itself can also be configured for either Vixen-style or Losmandy-D dovetail plates.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for Larger Visual Telescopes\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 starts to make particular sense with telescopes that are just large enough to make lighter Alt-Az mounts feel marginal.\u003c\/p\u003e\n\n\u003cp\u003eA 5-inch apochromatic refractor becomes a very capable lunar, planetary, double-star, and deep-sky instrument. A 180mm Maksutov offers enough focal length and aperture for serious high-power planetary observing without requiring a large equatorial mount. An 8-inch SCT adds substantially more light gathering while remaining compact enough to suit a counterweight-free Alt-Az system very well.\u003c\/p\u003e\n\n\u003cp\u003eThe mount is also unusually well suited to large astronomical binoculars. Moving the saddle to its binocular position lets the HAZ46 provide GoTo and tracking while preserving the comfortable observing geometry that makes binocular telescopes so enjoyable in the first place.\u003c\/p\u003e\n\n\u003cp\u003eFor outreach, that payload-to-weight ratio has another advantage: you can bring a substantial telescope without bringing a substantial mount system along with it.\u003c\/p\u003e\n\n\u003ch3\u003eUnder the Night Sky\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 earns its keep when magnification goes up.\u003c\/p\u003e\n\n\u003cp\u003ePut Jupiter in the field with a 180mm Maksutov and you can wait for moments of good seeing without continually nudging the telescope back into position. Saturn remains centered while you study the Cassini Division and look for fainter moons. On the Moon, a crater field stays put while you work along the terminator at high power.\u003c\/p\u003e\n\n\u003cp\u003eThat same tracking is valuable for double stars. Rather than spending the night finding and recentering one pair after another, GoTo handles the move and tracking gives you time to concentrate on the split.\u003c\/p\u003e\n\n\u003cp\u003eWith a 5-inch refractor, the emphasis shifts toward wide, clean views of open clusters, nebulae, and Milky Way fields. With a larger SCT, globular clusters, planetary nebulae, galaxies, lunar detail, and planets become the natural territory.\u003c\/p\u003e\n\n\u003cp\u003eWith a binocular telescope on top, the HAZ46 becomes a completely different kind of instrument: two-eyed visual observing with GoTo and tracking rather than a heavy binocular assembly that has to be repositioned manually after every target.\u003c\/p\u003e\n\n\u003ch3\u003ePark It and Come Back Later\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 can preserve its alignment information between observing sessions when it is parked correctly and left physically undisturbed.\u003c\/p\u003e\n\n\u003cp\u003eBefore shutting down, use one of the mount's parking positions. The controller retains the alignment information and reference points associated with that position.\u003c\/p\u003e\n\n\u003cp\u003eIf the mount remains in that parked position and the tripod is not moved, you can power it on later without necessarily repeating the entire initial setup.\u003c\/p\u003e\n\n\u003cp\u003eThat can be particularly useful at home or at a multi-night observing site where the mount remains assembled.\u003c\/p\u003e\n\n\u003cp\u003eIf you move the mount, tripod, or telescope out of the stored relationship, perform the normal alignment again.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eHAZ46 owners have used the mount with an unusually broad range of equipment, including 5-inch refractors, 180mm Maksutovs, Newtonians, binocular telescopes, and solar setups.\u003c\/p\u003e\n\n\u003cp\u003eOne detailed Cloudy Nights review describes traveling with a 127mm triplet and the HAZ46 in a very small car, then being up and observing within roughly 10–15 minutes of reaching the site. The same owner found the mount rigid, quick to settle, and comfortable at high magnification with several very different telescope types. :chatgpt-content-reference{index=\"6\"}\u003c\/p\u003e\n\n\u003cp\u003eThe owner's experience with parking was also useful: after parking and powering the mount down for several hours without moving it, the system retained its reference well enough to return accurately to a morning target.\u003c\/p\u003e\n\n\u003cp\u003eThat's a good example of where the HAZ46 fits. It is not simply trying to carry the largest possible telescope. It is trying to make a capable visual telescope easier to use frequently.\u003c\/p\u003e\n\n\u003ch3\u003eWhat About Astrophotography?\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 is an Alt-Az mount, so traditional long-exposure deep-sky astrophotography is not its intended job.\u003c\/p\u003e\n\n\u003cp\u003eAs an Alt-Az mount tracks across the sky, the field gradually rotates relative to the camera. That becomes increasingly visible as individual exposures become longer.\u003c\/p\u003e\n\n\u003cp\u003eLunar, planetary, and solar imaging are different. Those applications generally use video or large numbers of very short exposures, making field rotation much less important. Short-exposure electronic-assisted observing and live stacking can also be practical depending on the target, camera, exposure length, and software.\u003c\/p\u003e\n\n\u003cp\u003eFor conventional multi-minute guided exposures of galaxies and nebulae, use an equatorial mount.\u003c\/p\u003e\n\n\u003ch3\u003eTripod and MiniPier Choices\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 mounts through a 3\/8\"-16 threaded base and can be used with several support options.\u003c\/p\u003e\n\n\u003cp\u003eiOptron's 8061A carbon-fiber tripod is the lightweight companion to the HAZ46. It keeps the entire system highly portable and is particularly attractive when the goal is to minimize the weight carried to the observing site.\u003c\/p\u003e\n\n\u003cp\u003eWith longer or more demanding telescope systems, tripod rigidity becomes increasingly important. A 44 lb payload rating does not mean every 44 lb configuration will behave identically on every tripod.\u003c\/p\u003e\n\n\u003cp\u003eLong refractors may also need additional height to keep the diagonal, focuser, or camera equipment clear of the tripod legs near the zenith.\u003c\/p\u003e\n\n\u003cp\u003eiOptron's current \u003cstrong\u003e8044 MiniPier\u003c\/strong\u003e provides approximately 7 inches (178mm) of additional height and can provide three-point fine leveling when used with the 8061A carbon-fiber tripod.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eiOptron HAZ46 strain-wave Alt-Az GoTo mount head\u003c\/li\u003e\n\u003cli\u003eBuilt-in 11.1V, 4.4Ah rechargeable lithium-ion battery\u003c\/li\u003e\n\u003cli\u003eConvertible Vixen \/ Losmandy-D dovetail saddle\u003c\/li\u003e\n\u003cli\u003eGo2Nova 8409 hand controller\u003c\/li\u003e\n\u003cli\u003e6P6C coiled hand-controller cable\u003c\/li\u003e\n\u003cli\u003eUSB cable for computer connection and firmware updates\u003c\/li\u003e\n\u003cli\u003e100–240V AC \/ 12.6V 2A battery charger for indoor use\u003c\/li\u003e\n\u003cli\u003eCarrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNot included:\u003c\/strong\u003e tripod or MiniPier.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much does the HAZ46 weigh?\u003c\/strong\u003e\u003cbr\u003e\nThe mount head weighs 12.3 lb (5.6 kg) with its dovetail saddle installed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can the HAZ46 carry?\u003c\/strong\u003e\u003cbr\u003e\niOptron rates it for 44 lb (20 kg), assuming the payload's center of gravity is approximately 200mm from the mount's rotation axis.

Wireless connectivity is provided through the included Go2Nova 8409 hand controller.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow fast does it slew?\u003c\/strong\u003e\u003cbr\u003e\nThe maximum published slew speed is 6° per second.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I control it from a phone or tablet?\u003c\/strong\u003e\u003cbr\u003e\nYes. iOptron supports Commander Lite and compatible applications such as SkySafari through the hand controller's Wi-Fi connection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan the HAZ46 carry a 180mm Maksutov?\u003c\/strong\u003e\u003cbr\u003e\nA typical 180mm Maksutov falls well within the published payload rating and its relatively compact tube geometry makes it a natural match for the HAZ46. Include the diagonal, finder, eyepiece, dew equipment, and other accessories when calculating total load.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan it carry an 8-inch or 9.25-inch SCT?\u003c\/strong\u003e\u003cbr\u003e\nMany configurations fall within the 44 lb rating, particularly because SCTs are comparatively compact for their aperture. The complete weight and center of gravity should still be considered before choosing a support system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan it carry a 5- or 6-inch refractor?\u003c\/strong\u003e\u003cbr\u003e\nWeight alone may put many refractors within the published limit, but tube length and moment arm become increasingly important as aperture and focal length grow. A long refractor may benefit from a more rigid tripod and a MiniPier even when its total weight is comfortably under 44 lb.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs the HAZ46 suitable for large binoculars?\u003c\/strong\u003e\u003cbr\u003e\nYes. Large-binocular mounting is an intended feature of the design. The saddle can be repositioned on top of the mount for a more useful binocular-observing geometry.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan the HAZ46 do astrophotography?\u003c\/strong\u003e\u003cbr\u003e\nIt is well suited to lunar, planetary, and solar imaging and can also be used for some short-exposure EAA and live-stacking work. It is not designed for traditional long-exposure deep-sky imaging because Alt-Az tracking produces field rotation over time.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill it remember its alignment after I turn it off?\u003c\/strong\u003e\u003cbr\u003e\nIt can retain its alignment information when properly parked and left physically undisturbed. If the mount or tripod is moved after parking, perform the normal alignment procedure again.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHAZ31 or HAZ46?\u003c\/strong\u003e\u003cbr\u003e\nThe HAZ31 emphasizes minimum weight: an 8.2 lb mount head with a 31 lb payload rating. The HAZ46 increases capacity to 44 lb, weighs 12.3 lb, and adds an internal rechargeable battery. The better choice depends on the complete telescope's weight, length, center of gravity, and how much capacity you want in reserve.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat tripod works with the HAZ46?\u003c\/strong\u003e\u003cbr\u003e\niOptron's 8061A carbon-fiber tripod is a current lightweight option. The mount uses a 3\/8\"-16 mounting connection, and other properly configured supports can also be used.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat MiniPier fits the HAZ46?\u003c\/strong\u003e\u003cbr\u003e\niOptron's current 8044 MiniPier fits the HAZ46 and adds approximately 7 inches of height. When used with the 8061A tripod, it also provides three-point fine leveling.\u003c\/p\u003e\n\n\u003ch3\u003eAccessories\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eiOptron 8061A Carbon Fiber Tripod, Version A (sold separately)\u003c\/strong\u003e: a lightweight 5 lb support that keeps the HAZ46 system highly portable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eiOptron 8044 MiniPier (sold separately)\u003c\/strong\u003e: adds approximately 7 inches of height for long refractors and rear-mounted accessories and provides three-point leveling when paired with the 8061A tripod.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExternal power source (optional)\u003c\/strong\u003e: useful for extended observing sessions or when you want to operate the mount without depending solely on its internal battery.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe HAZ46 is for the observer who owns a substantial telescope but doesn't want the mount to turn every clear night into a project.\u003c\/p\u003e\n\n\u003cp\u003eA 12.3 lb mount head capable of carrying up to 44 lb without a counterweight changes the practical side of using a 5-inch refractor, large Maksutov, SCT, or binocular telescope. Add the internal battery and the usual pile of mount accessories gets smaller still.\u003c\/p\u003e\n\n\u003cp\u003eThe built-in GPS, automatic zero-position search, GoTo, tracking, 8409 hand controller, and Wi-Fi handle the repetitive work while the strain-wave drives provide the torque needed to carry the telescope without conventional balancing.\u003c\/p\u003e\n\n\u003cp\u003eIt is not intended to replace an equatorial mount for long-exposure astrophotography. That's not the point. The HAZ46 is about making a serious visual telescope easier to take outside, easier to travel with, and easier to use once you get there.\u003c\/p\u003e\n\n\u003cp\u003eIf the mount has been the part of your larger telescope that makes you think twice about observing, that's the problem the HAZ46 was designed to solve.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

A cooled camera gets added, then a guide camera, electronic focuser, filter wheel, USB hub, power distribution, and eventually a laptop, mini PC, Raspberry Pi, or dedicated astronomy controller to run everything.\u003c\/p\u003e\n\n\u003cp\u003eThe HAE69B puts that computer into the mount itself.\u003c\/p\u003e\n\n\u003cp\u003eiMate comes preloaded with KStars for planetarium and target selection, Ekos for imaging automation, and INDI drivers for compatible astronomical equipment. Once the equipment profile is configured, the system can handle GoTo, plate solving, autofocus, guiding, capture sequences, scheduling, and other parts of an automated imaging session.\u003c\/p\u003e\n\n\u003cp\u003eThe computer includes 32GB of internal eMMC storage plus a microSD slot supporting cards up to 64GB. One USB 3.0 port, two USB 2.0 ports, and three 12V outputs let cameras and accessories connect directly at the mount rather than requiring another collection of hubs and power boxes around the tripod.\u003c\/p\u003e\n\n\u003cp\u003eFor a large imaging system that gets assembled and taken down regularly, that integration can make as much difference to setup time as the counterweight-free mount itself.\u003c\/p\u003e\n\n\u003ch3\u003eRemote Control Without Leaving the Computer Outside\u003c\/h3\u003e\n\n\u003cp\u003eiMate runs the imaging software onboard, but you still need a screen from which to control it.\u003c\/p\u003e\n\n\u003cp\u003eThe system creates its own Wi-Fi connection and can be accessed remotely from a computer, tablet, or compatible mobile device. The astronomy applications continue running on iMate; the device in your hand simply becomes the interface to the computer inside the mount.\u003c\/p\u003e\n\n\u003cp\u003eThat means a laptop does not have to remain beside the telescope all night. Configure the system, start the sequence, and the onboard computer continues doing the work at the mount.\u003c\/p\u003e\n\n\u003cp\u003eThere is also an Ethernet connection on the iMate hardware for users building more customized installations, although iOptron describes that port primarily for customer DIY applications rather than as the normal portable-control method.\u003c\/p\u003e\n\n\u003ch3\u003eYou Are Not Locked Into iMate\u003c\/h3\u003e\n\n\u003cp\u003eOne of the most useful parts of the HAE69B design is that the integrated computer is an option, not a commitment.\u003c\/p\u003e\n\n\u003cp\u003eThe mount can also be controlled directly through the USB-C port on its base. Windows users can work through iOptron Commander and ASCOM, while compatible INDI software provides additional options on macOS, Linux, and Raspberry Pi-based systems.\u003c\/p\u003e\n\n\u003cp\u003eIf your imaging setup is already built around NINA, a mini PC, StellarMate, or another control environment, you can continue using it.\u003c\/p\u003e\n\n\u003cp\u003eIf you are traveling and want the cleanest self-contained system possible, use iMate.\u003c\/p\u003e\n\n\u003cp\u003eThat flexibility makes the B model considerably more useful than it would be if the onboard computer were the only way to operate the mount.\u003c\/p\u003e\n\n\u003ch3\u003e69 Pounds Without Counterweights\u003c\/h3\u003e\n\n\u003cp\u003eUnderneath the computer is still the feature that makes the HAE69 platform unusual: 69 pounds of counterweight-free payload in a mount weighing less than 20 pounds.\u003c\/p\u003e\n\n\u003cp\u003eThat gives the HAE69B room for genuinely substantial equipment — large refractors, SCTs, RCs, astrographs, cooled cameras, filter wheels, electronic focusers, rotators, guiding equipment, and the assortment of adapters that inevitably becomes part of a mature imaging system.\u003c\/p\u003e\n\n\u003cp\u003eAdd the optional counterweight system and iOptron increases the published payload to 79 lb.\u003c\/p\u003e\n\n\u003cp\u003eThere is an important qualification to those numbers. The current iOptron rating assumes the payload's center of gravity is approximately 250mm from the RA rotation axis. A compact 50-pound SCT and a long 50-pound refractor do not place the same mechanical load on the mount.\u003c\/p\u003e\n\n\u003cp\u003eThat matters increasingly as the telescope becomes larger. Tube length, diameter, dew shields, rear-mounted cameras, focusers, and filter wheels can all move mass farther from the axis and increase the leverage the drive has to manage.\u003c\/p\u003e\n\n\u003cp\u003eThink about the whole telescope system — not just the number on the scale.\u003c\/p\u003e\n\n\u003ch3\u003eGuiding the Standard HAE69B\u003c\/h3\u003e\n\n\u003cp\u003eThe standard HAE69B does not include the high-precision RA encoder found in the HAE69B-EC.\u003c\/p\u003e\n\n\u003cp\u003eiOptron specifies periodic error below ±15 arcseconds with a 270-second strain-wave gear period. For demanding long-exposure astrophotography, guiding is the appropriate way to continuously correct the remaining tracking error.\u003c\/p\u003e\n\n\u003cp\u003eStrain-wave mounts can respond differently to guiding than traditional worm-drive mounts because the tracking rate can change relatively quickly through portions of the gear cycle. That often makes relatively short guide exposures useful, but there is no single setting that belongs on every HAE69B.\u003c\/p\u003e\n\n\u003cp\u003eA short refractor, an 11-inch SCT, and a large RC are completely different guiding problems even when the same mount sits underneath them.\u003c\/p\u003e\n\n\u003cp\u003eSeeing, guide-camera sensitivity, image scale, telescope geometry, tripod or pier rigidity, and wind all influence the final result. Tune the system from the stars in the actual subframes rather than trying to reproduce somebody else's RMS number.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eThe Cloudy Nights discussion around the HAE69B tends to focus on iMate because that is what separates this version from the other HAE69 models.\u003c\/p\u003e\n\n\u003cp\u003eThe appeal is obvious to users building portable systems: the computer, USB connections, accessory power, KStars, Ekos, and INDI are already part of the mount, which can eliminate another mini PC and reduce the number of cables running around the system.\u003c\/p\u003e\n\n\u003cp\u003eReal-world experience also shows that iMate is best understood as a small Linux astrophotography computer rather than a one-button appliance. Owners have reported some initial work getting cameras, guide cameras, focusers, and software profiles configured correctly. In one early HAE69B discussion, an owner had difficulty getting multiple QHY devices connected through iMate, while the same hardware worked through an external StellarMate computer. That owner also noted that Wi-Fi responsiveness was good and the simplified cabling was appealing once the system was configured.\u003c\/p\u003e\n\n\u003cp\u003eAnother owner ultimately chose to continue using an external mini PC with NINA while working through iMate configuration issues, which highlights an important strength of the HAE69B: the onboard computer can be bypassed. You can use iMate when its integrated workflow suits the session and connect your preferred external computer when it does not.\u003c\/p\u003e\n\n\u003cp\u003eThat is probably the most useful way to approach the B model. The onboard computer gives you another way to build the imaging system without taking the familiar alternatives away.\u003c\/p\u003e\n\n\u003ch3\u003eEQ for Imaging, Alt-Az for Visual\u003c\/h3\u003e\n\n\u003cp\u003eThe HAE69B can operate in either equatorial or Alt-Az mode.\u003c\/p\u003e\n\n\u003cp\u003eIn equatorial mode, proper polar alignment provides the geometry required for long-exposure astrophotography, while iMate can handle the control and automation side of the imaging session.\u003c\/p\u003e\n\n\u003cp\u003eSwitch to Alt-Az mode and the same head becomes a high-capacity GoTo visual platform without requiring a conventional polar-alignment routine.\u003c\/p\u003e\n\n\u003cp\u003eThat is especially useful with telescopes in this payload class. A large SCT or refractor can spend one night gathering hours of camera data and the next pointed at the Moon, planets, globular clusters, or double stars with an eyepiece.\u003c\/p\u003e\n\n\u003cp\u003eAlt-Az mode can also be useful for EAA and outreach using short live-stacked exposures, where rapid setup may matter more than eliminating field rotation over long integrations.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eiOptron HAE69B strain-wave AZ\/EQ mount head\u003c\/li\u003e\n\u003cli\u003eIntegrated iMate computer\u003c\/li\u003e\n\u003cli\u003eDual Vixen\/Losmandy-D dovetail saddle\u003c\/li\u003e\n\u003cli\u003e12V\/6A AC\/DC power adapter for indoor use\u003c\/li\u003e\n\u003cli\u003eUSB-C computer\/firmware cable\u003c\/li\u003e\n\u003cli\u003eAluminum carrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eAvailable separately:\u003c\/strong\u003e Go2Nova 8411 OLED hand controller, external iPolar electronic polar scope, LiteRoc tripod, Tri-Pier, counterweight shaft and counterweight, MiniPier extension, iGuider, and other compatible accessories.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat makes the HAE69B different from the HAE69C?\u003c\/strong\u003e\u003cbr\u003e\nThe defining feature of the HAE69B is its integrated iMate astronomy computer. Both mounts use the same basic dual strain-wave platform and share the same published payload capacity, but the B model adds KStars, Ekos, INDI device control, onboard storage, USB connectivity, and accessory power.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the HAE69B have the high-precision RA encoder?\u003c\/strong\u003e\u003cbr\u003e\nNo. The standard HAE69B does not include the high-precision RA encoder. If you want the HAE69 with both iMate and the encoder with Real-Time PEC, that model is the HAE69B-EC.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat can iMate control?\u003c\/strong\u003e\u003cbr\u003e\nThrough KStars, Ekos, and INDI drivers, iMate can work with compatible imaging cameras, guide cameras, electronic focusers, filter wheels, and other astronomical equipment in addition to controlling the mount itself.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I really image without leaving a laptop at the telescope?\u003c\/strong\u003e\u003cbr\u003e\nYes. The imaging applications run on the computer built into the mount. You still use another device to access and configure iMate remotely, but the computer running the session remains inside the HAE69B.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I have to use iMate?\u003c\/strong\u003e\u003cbr\u003e\nNo. The mount can also be controlled directly through USB-C from an external computer using compatible ASCOM or INDI software.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can the HAE69B carry?\u003c\/strong\u003e\u003cbr\u003e\niOptron rates it for 69 lb (31 kg) without a counterweight and 79 lb (36 kg) with the optional counterweight system. The current rating assumes the payload center of gravity is approximately 250mm from the RA axis, so telescope geometry matters along with total weight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eShould I guide the HAE69B?\u003c\/strong\u003e\u003cbr\u003e\nFor demanding long-exposure imaging, yes. The standard HAE69B does not have the RA encoder of the B-EC version and is specified at less than ±15 arcseconds periodic error. The exact guiding settings should be tuned to the telescope, image scale, seeing, and guide system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it support ST-4 guiding?\u003c\/strong\u003e\u003cbr\u003e\nYes. The HAE69B includes an ST-4-compatible autoguider port. Software-based guiding through Ekos, ASCOM, INDI, or other compatible systems can also be used.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it include a hand controller?\u003c\/strong\u003e\u003cbr\u003e\nNo. The current HE692B is sold without the handset. iOptron's 8411 Go2Nova OLED controller is available separately if you want physical controls and standalone GoTo operation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it include iPolar?\u003c\/strong\u003e\u003cbr\u003e\nNo. iOptron's external iPolar electronic polar scope is optional. The iMate software includes iPolarServer for use when an iPolar camera is connected.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes a tripod come with the mount?\u003c\/strong\u003e\u003cbr\u003e\nNo. The HAE69B is supplied without a tripod or pier so you can pair it with the support appropriate for your telescope and observing setup.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use it for visual observing?\u003c\/strong\u003e\u003cbr\u003e\nYes. The HAE69B can operate in Alt-Az mode for visual use as well as equatorial mode for astrophotography.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe HAE69B is not the encoder version of the HAE69. It is the integrated-computer version, and that gives it a very different reason to exist.\u003c\/p\u003e\n\n\u003cp\u003eYou still get the remarkable part of the HAE69 platform: 69 pounds of counterweight-free capacity in a mount weighing less than 20 pounds.\u003c\/p\u003e\n\n\u003cp\u003eWhat the B adds is the ability to build much of the imaging system around the mount itself. KStars, Ekos, INDI, onboard storage, USB connections, and accessory power are already there, allowing the mount, camera, guider, focuser, and filter wheel to become part of one integrated field system.\u003c\/p\u003e\n\n\u003cp\u003eAnd because direct USB-C control remains available, using iMate is a choice rather than a requirement. Run the onboard computer when its integration makes sense. Use your existing mini PC or laptop when another workflow fits the session better.\u003c\/p\u003e\n\n\u003cp\u003eFor the imager who wants the HAE69's substantial capacity but also wants fewer separate boxes and cables around a large portable rig, that is the reason to choose the HAE69B.\u003c\/p\u003e\n\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

With a lightweight yet powerful design, this mount is ideal for deep-sky imaging, planetary photography, and visual observation. Whether you’re setting up at home or traveling to a dark-sky site, the AM5N provides an easy-to-use, highly portable solution for capturing the night sky.\u003c\/p\u003e\n\u003ch3 data-end=\"645\" data-start=\"573\"\u003eHarmonic Drive Technology – Ultra-Smooth Tracking with No Backlash\u003c\/h3\u003e\n\u003cp data-end=\"924\" data-start=\"647\"\u003eUnlike traditional worm gear mounts, which can suffer from backlash and periodic error, the AM5N uses a strain wave harmonic reducer for smooth tracking and precise control. This eliminates backlash, reduces mechanical wear, and ensures more consistent long-exposure imaging.\u003c\/p\u003e\n\u003cp data-end=\"1142\" data-start=\"926\"\u003eWith a periodic error of just ±10 arcseconds, the AM5N provides excellent tracking. When paired with autoguiding, it can achieve sub-arcsecond accuracy, delivering pinpoint star images in deep-sky astrophotography.\u003c\/p\u003e\n\u003ch3 data-end=\"1207\" data-start=\"1144\"\u003eHeavy-Duty Mode – Enhanced Performance for Large Payloads\u003c\/h3\u003e\n\u003cp data-end=\"1419\" data-start=\"1209\"\u003eFor those using heavier telescopes, the AM5N includes a heavy-duty mode that optimizes the mount’s torque and tracking performance. This feature is particularly useful when imaging with setups over 22 pounds.\u003c\/p\u003e\n\u003cp data-end=\"1812\" data-start=\"1421\"\u003eIn standard mode, the mount operates with a balanced level of torque, ideal for lightweight to mid-range setups. Heavy-duty mode increases motor drive power, improving performance for heavier payloads and maintaining precise tracking for larger telescopes. This allows the AM5N to reach its full 44-pound payload capacity when using a counterweight while still delivering smooth operation.\u003c\/p\u003e\n\u003ch3 data-end=\"1864\" data-start=\"1814\"\u003eHigh Payload Capacity Without Counterweights\u003c\/h3\u003e\n\u003cp data-end=\"2142\" data-start=\"1866\"\u003eOne of the biggest advantages of the AM5N is its ability to support substantial payloads without requiring counterweights. The mount can handle up to 28.6 pounds without counterweights, making it well-suited for small to medium-sized refractors, Newtonians, and astrographs.\u003c\/p\u003e\n\u003cp data-end=\"2378\" data-start=\"2144\"\u003eFor larger optical tubes, the mount can support up to 44 pounds with a counterweight.

It does not function as a power pass-through for the mount.\u003c\/p\u003e\n\u003cp data-end=\"2925\" data-start=\"2599\"\u003eThe USB-C port is used for firmware updates and PC control via ASCOM or INDI, but the mount itself must be powered separately using the 12V DC input. This is crucial for users planning their power setup, as attempting to power the mount via USB-C will not work. A dedicated 12V power source is required for proper operation.\u003c\/p\u003e\n\u003ch3 data-end=\"2993\" data-start=\"2927\"\u003eDual-Mode Operation – Equatorial and Alt-Azimuth Flexibility\u003c\/h3\u003e\n\u003cp data-end=\"3131\" data-start=\"2995\"\u003eThe AM5N can operate in both equatorial and alt-azimuth modes, making it a versatile choice for astrophotography and visual observing.\u003c\/p\u003e\n\u003cp data-end=\"3465\" data-start=\"3133\"\u003eEquatorial mode is the preferred setting for long-exposure astrophotography, as it compensates for Earth’s rotation and prevents field rotation. Alt-azimuth mode is ideal for visual observation, planetary imaging, and electronically assisted astronomy, providing simple and intuitive tracking without the need for polar alignment.\u003c\/p\u003e\n\u003cp data-end=\"3563\" data-start=\"3467\"\u003eSwitching between the two modes is quick and does not require additional tools or accessories.\u003c\/p\u003e\n\u003ch3 data-end=\"3623\" data-start=\"3565\"\u003eSeamless Control – ASIAIR, WiFi, and Hand Controller\u003c\/h3\u003e\n\u003cp data-end=\"3723\" data-start=\"3625\"\u003eZWO designed the AM5N with multiple control options to fit different astrophotography workflows.\u003c\/p\u003e\n\u003cul data-end=\"4236\" data-start=\"3725\"\u003e\n\u003cli data-end=\"3891\" data-start=\"3725\"\u003eThe ASI Mount App allows for wireless control via WiFi or Bluetooth, providing an easy way to manage slewing, tracking, and alignment from a smartphone or tablet.\u003c\/li\u003e\n\u003cli data-end=\"4003\" data-start=\"3892\"\u003eThe included hand controller allows for manual adjustments and fine-tuning without needing a mobile device.\u003c\/li\u003e\n\u003cli data-end=\"4114\" data-start=\"4004\"\u003eFull ASIAIR compatibility enables a completely wireless astrophotography experience with no excess cables.\u003c\/li\u003e\n\u003cli data-end=\"4236\" data-start=\"4115\"\u003ePC control via ASCOM and INDI allows for automation using third-party software such as NINA, Stellarium, and TheSkyX.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-end=\"4424\" data-start=\"4238\"\u003eThese options give users the flexibility to control the mount in the way that best suits their needs, whether through mobile devices, a physical hand controller, or full PC automation.\u003c\/p\u003e\n\u003ch3 data-end=\"4491\" data-start=\"4426\"\u003eZWO TC40 Carbon Fiber Tripod – Stability Without the Weight\u003c\/h3\u003e\n\u003cp data-end=\"4661\" data-start=\"4493\"\u003eThe TC40 carbon fiber tripod is an excellent companion for the AM5N.

HAE29B Dual Equatorial and Alt-Azimuth Strain Wave Mount Head with iPolar","description":"\u003cp\u003eThe iOptron HAE29B takes the portability of a strain-wave mount and adds something most mounts still expect you to supply separately: the computer that runs the imaging session.\u003c\/p\u003e\n\n\u003cp\u003eThe mount head weighs just 8.6 lb (3.9 kg), yet iOptron rates it to carry 29 lb (13 kg) without a counterweight and up to 40 lb (18 kg) with the optional counterweight system. Inside the mount is iOptron's iMate computer, a 64-bit ARM-based controller preloaded with KStars, Ekos, and INDI support for mounts, cameras, focusers, filter wheels, and other imaging equipment.\u003c\/p\u003e\n\n\u003cp\u003eThat makes the HAE29B more than a lightweight GoTo head. It can become the control center for an entire portable astrophotography system, with camera control, focusing, guiding, sequencing, plate solving, and image capture handled at the mount instead of by a separate laptop or control box.\u003c\/p\u003e\n\n\u003cp\u003eIf you prefer your own computer or imaging controller, you are not locked into iMate.

Plenty of portable mounts now use strain-wave gearing. The difference is that iOptron has built an astronomy computer directly into the mount.\u003c\/p\u003e\n\n\u003cp\u003eiMate comes with KStars for planetarium and target selection, Ekos for imaging automation, and INDI drivers for controlling astronomical equipment. A compatible camera, focuser, filter wheel, and guider can all connect to the iMate, allowing the same system to handle the mount and the rest of the imaging train.\u003c\/p\u003e\n\n\u003cp\u003eThe onboard computer includes 32GB of eMMC storage, plus a microSD slot for up to another 64GB. That gives it enough local storage to run and capture an automated imaging session without requiring a laptop to remain beside the telescope all night.\u003c\/p\u003e\n\n\u003cp\u003eThe accessory connections are built around the same idea. One USB 3.0 port, two USB 2.0 ports, and three 12V outputs let much of the imaging equipment connect at the mount rather than running separate power and data cables down to the tripod.\u003c\/p\u003e\n\n\u003cp\u003eFor a portable rig, that can make setup considerably cleaner: mount, telescope, imaging equipment, and control computer become one integrated system rather than several separate boxes that have to be connected every time you set up.\u003c\/p\u003e\n\n\u003ch3\u003eBut You Are Not Locked Into iMate\u003c\/h3\u003e\n\n\u003cp\u003eAn integrated computer is useful only if it fits the way you like to work, so one of the better features of the HAE29B is that iMate is not the only way to control it.\u003c\/p\u003e\n\n\u003cp\u003eThe mount can also be connected directly to a computer through the USB-C port on the mount base. Windows users can work through iOptron Commander and ASCOM, while compatible INDI-based software provides options for macOS, Linux, and Raspberry Pi systems.\u003c\/p\u003e\n\n\u003cp\u003eThat means you can use iMate as the heart of a compact all-in-one system, or treat the HAE29B more like a conventional mount and connect it to the imaging computer or controller you already know.\u003c\/p\u003e\n\n\u003cp\u003eObservers who prefer a physical handset can also add iOptron's optional Go2Nova 8411 OLED controller.\u003c\/p\u003e\n\n\u003ch3\u003e29 Pounds Without Counterweights\u003c\/h3\u003e\n\n\u003cp\u003eThe HAE29B retains the feature that made the HAE29 family attractive in the first place: a great deal of payload without a great deal of mount.\u003c\/p\u003e\n\n\u003cp\u003eiOptron rates the HAE29B for 29 lb (13 kg) without a counterweight. Add the optional counterweight shaft and weight and the rating increases to 40 lb (18 kg).\u003c\/p\u003e\n\n\u003cp\u003eThere is an important qualification to those numbers. iOptron bases the payload rating on the center of gravity being approximately 200mm from the RA rotation axis. A compact astrograph and a long refractor may weigh exactly the same while presenting very different loads to the drive.\u003c\/p\u003e\n\n\u003cp\u003eThat makes the HAE29B especially well suited to compact refractors, astrographs, SCTs, and similarly concentrated imaging systems. As telescope length and moment arm increase, leaving additional margin below the published weight rating becomes increasingly important.\u003c\/p\u003e\n\n\u003cp\u003eThe optional counterweight system is there when a particular payload benefits from it, but many appropriately sized systems can operate without one — which is a large part of the reason to choose a strain-wave mount in the first place.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eDiscussion of the HAE29B on Cloudy Nights has focused less on the basic mount mechanics and more on the feature that makes the B version different: iMate.\u003c\/p\u003e\n\n\u003cp\u003eOwners like the idea of having the imaging computer, power distribution, USB connections, and mount control collected into one portable package. One HAE29B owner described it as a nice mobile setup after connecting a DSLR, guide camera, focuser, and polar-alignment system through the iMate.\u003c\/p\u003e\n\n\u003cp\u003eThe community discussion also makes an important practical point: iMate has its own learning curve. Because it is built around KStars, Ekos, and INDI rather than a closed appliance-style interface, getting cameras, guiders, focusers, and software settings matched correctly can require some initial configuration. Owners have reported that once those pieces are sorted out the system becomes considerably more useful, but this is still an astronomy computer rather than a one-button smart telescope.\u003c\/p\u003e\n\n\u003cp\u003eFor users who already have a preferred control system, the good news is that the HAE29B does not have to be built entirely around iMate. Direct USB control gives you another path, so the onboard computer can be a major feature when you want it without dictating every future imaging workflow.\u003c\/p\u003e\n\n\u003cp\u003eThat flexibility may be the most useful way to look at the B version: it gives you an integrated computer when portability and cable reduction matter, while still leaving the door open to a more traditional external-control setup.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eiOptron HAE29B strain-wave AZ\/EQ mount head\u003c\/li\u003e\n\u003cli\u003eBuilt-in iMate computer\u003c\/li\u003e\n\u003cli\u003eDual Vixen\/Losmandy-D dovetail saddle\u003c\/li\u003e\n\u003cli\u003eAC\/DC power adapter for indoor use\u003c\/li\u003e\n\u003cli\u003eFitted carrying case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eAvailable separately:\u003c\/strong\u003e iPolar electronic polar scope, Go2Nova 8411 OLED hand controller, tripod or Tri-Pier, counterweight shaft and counterweight, MiniPier extensions, and other compatible accessories.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat makes the HAE29B different from the HAE29C?\u003c\/strong\u003e\u003cbr\u003e\nThe defining feature of the HAE29B is its built-in iMate astronomy computer. It comes preloaded with KStars, Ekos, and INDI support and can control much of an imaging system directly from the mount.

The rating assumes the payload center of gravity is approximately 200mm from the RA axis, so telescope geometry matters along with weight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a counterweight?\u003c\/strong\u003e\u003cbr\u003e\nNot for an appropriately sized payload within the counterweight-free rating.

It is the integrated-computer version, and that gives it a very different reason to exist.\u003c\/p\u003e\n\n\u003cp\u003eYou still get the advantages of the HAE29 platform: strain-wave drives on both axes, a 29 lb counterweight-free payload, dual Vixen\/Losmandy compatibility, EQ and Alt-Az operation, and a mount head that weighs less than nine pounds.\u003c\/p\u003e\n\n\u003cp\u003eWhat the B adds is the ability to build the rest of the imaging system around the mount itself. KStars, Ekos, INDI, onboard storage, USB connections, and 12V accessory outputs are already there, allowing a camera, guider, focuser, and filter wheel to become part of one compact field system.\u003c\/p\u003e\n\n\u003cp\u003eFor the imager who wants fewer separate boxes, fewer long cables, and less equipment to assemble at a dark site, that integration is the real reason to choose the HAE29B.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;

The HAE43C already does that. What separates the B version is iMate.\u003c\/p\u003e\n\n\u003cp\u003eAstrophotography rigs have a habit of accumulating boxes. The telescope gets a cooled camera, then a guide camera, electronic focuser, filter wheel, USB hub, power distribution, and eventually a laptop, mini PC, or dedicated astronomy controller to run everything.\u003c\/p\u003e\n\n\u003cp\u003eiMate moves much of that control hardware into the mount itself.\u003c\/p\u003e\n\n\u003cp\u003eIts onboard computer comes preloaded with KStars for planetarium and target selection, Ekos for imaging automation, and INDI drivers for compatible astronomical equipment. Once the system is configured, Ekos can handle GoTo, plate solving, autofocus, guiding, capture sequences, and other parts of an automated imaging session while the software itself runs inside the mount.\u003c\/p\u003e\n\n\u003cp\u003eThe iMate also provides one USB 3.0 port, two USB 2.0 ports, and three 12V outputs, so much of the equipment can connect close to the telescope instead of requiring another hub and power box hanging from the tripod.\u003c\/p\u003e\n\n\u003cp\u003eFor an imaging system that gets assembled and taken down regularly, fewer separate components can make a meaningful difference.\u003c\/p\u003e\n\n\u003ch3\u003eRemote Control Without Leaving a Laptop Outside\u003c\/h3\u003e\n\n\u003cp\u003eThe computer is inside the HAE43B, but you still need a way to interact with it.\u003c\/p\u003e\n\n\u003cp\u003eiMate creates its own Wi-Fi network and can be accessed remotely from a computer, tablet, or other compatible device. The applications run on the iMate itself; your remote device is simply giving you access to the desktop and controls.\u003c\/p\u003e\n\n\u003cp\u003eThat means the laptop does not have to remain tethered to the telescope all night. Once the equipment profile and imaging sequence are configured, the onboard computer can continue handling the session at the mount.\u003c\/p\u003e\n\n\u003cp\u003eThis is particularly useful for a portable setup where reducing hardware and cable clutter is part of the reason for choosing a strain-wave mount in the first place.\u003c\/p\u003e\n\n\u003ch3\u003eYou Are Not Locked Into iMate\u003c\/h3\u003e\n\n\u003cp\u003eAn integrated computer is much more useful when it remains optional.\u003c\/p\u003e\n\n\u003cp\u003eThe HAE43B can also be controlled directly through the USB-C port on the mount base. Windows users can work through iOptron Commander and ASCOM, while compatible third-party INDI software provides additional control options on other platforms.\u003c\/p\u003e\n\n\u003cp\u003eIf you already have a NINA-based mini PC, ASIAIR-compatible workflow, Raspberry Pi, or another control system you prefer, you can continue using it rather than rebuilding the entire imaging setup around iMate.\u003c\/p\u003e\n\n\u003cp\u003eThat makes iMate an additional capability instead of a software commitment.\u003c\/p\u003e\n\n\u003ch3\u003e44 Pounds Without Counterweights\u003c\/h3\u003e\n\n\u003cp\u003eUnderneath the computer is still the feature that makes the HAE43 platform unusual: 44 pounds of counterweight-free payload in a mount weighing less than 13 pounds.\u003c\/p\u003e\n\n\u003cp\u003eThat leaves room for a substantial telescope and imaging train without requiring the traditional shaft and stack of counterweights every time you set up. Add the optional counterweight system and the rated capacity rises to 55 lb.\u003c\/p\u003e\n\n\u003cp\u003eThere is an important qualification to those numbers. iOptron bases the payload rating on the center of gravity being approximately 200mm from the RA rotation axis. A compact 35-pound SCT or astrograph and a long 35-pound refractor do not present the same load to the mount.\u003c\/p\u003e\n\n\u003cp\u003eThat makes telescope geometry just as important as scale weight. Compact astrographs, SCTs, and reasonably sized refractors are particularly natural matches. As tube length and moment arm increase, leaving additional margin below the published payload becomes increasingly sensible.\u003c\/p\u003e\n\n\u003cp\u003eThe optional counterweight gives you another tool when a particular configuration benefits from it. Counterweight-free is a capability, not a requirement.\u003c\/p\u003e\n\n\u003ch3\u003eGuiding the Standard HAE43B\u003c\/h3\u003e\n\n\u003cp\u003eThe standard HAE43B does not include the high-precision RA encoder found in the HAE43B-EC.\u003c\/p\u003e\n\n\u003cp\u003eiOptron specifies the underlying strain-wave drive at less than ±18 arcseconds of periodic error, with a 270-second RA gear period. For demanding long-exposure astrophotography, plan on guiding the standard B model when the image scale requires it.\u003c\/p\u003e\n\n\u003cp\u003eStrain-wave mounts can benefit from a somewhat different guiding approach than conventional worm-drive mounts because the tracking rate can change relatively quickly through portions of the gear cycle. Shorter guide exposures are therefore common, but there is no single setting that belongs on every HAE43B.\u003c\/p\u003e\n\n\u003cp\u003eSeeing, focal length, guide-camera sensitivity, telescope geometry, and the support underneath the mount all affect the result. Tune the guider from the stars in your actual exposures rather than trying to reproduce someone else's RMS number.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eThe conversation around iMate on Cloudy Nights is interesting because users see the same appeal that is obvious on paper: combining the mount and imaging computer can make a portable system considerably cleaner.\u003c\/p\u003e\n\n\u003cp\u003eMembers familiar with KStars, Ekos, and INDI generally like the open architecture and the ability to use cameras, focusers, filter wheels, and other equipment from different manufacturers rather than being restricted to a single hardware ecosystem.\u003c\/p\u003e\n\n\u003cp\u003eThere is a learning curve, however. Community reports from owners using the iMate platform show that getting individual cameras, guide cameras, focusers, and INDI drivers configured can require some initial work. One owner described the Wi-Fi performance and reduced cabling positively while also working through device-connection and guiding configuration issues.\u003c\/p\u003e\n\n\u003cp\u003eThat is worth understanding before choosing the B model. iMate is closer to having a small Linux astrophotography computer built into the mount than to using a closed, one-button appliance. For an experienced imager who likes KStars, Ekos, INDI, and the freedom to configure the system, that openness can be a major advantage.\u003c\/p\u003e\n\n\u003cp\u003eAnd if iMate doesn't fit the workflow you eventually settle on, direct USB-C control means the mount itself remains useful with an external computer.

Both mounts use the same basic dual strain-wave platform and have the same published payload capacity, but the B model adds KStars, Ekos, INDI device control, onboard storage, USB connectivity, and accessory power.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the HAE43B have a high-precision RA encoder?\u003c\/strong\u003e\u003cbr\u003e\nNo. The standard HAE43B does not include the RA encoder. If you want the HAE43 with both iMate and the high-precision RA encoder, that model is the HAE43B-EC.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat can iMate control?\u003c\/strong\u003e\u003cbr\u003e\nThrough KStars, Ekos, and INDI drivers, iMate can work with compatible imaging cameras, guide cameras, electronic focusers, filter wheels, and other astronomical equipment in addition to controlling the mount itself.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a laptop?\u003c\/strong\u003e\u003cbr\u003e\nYou do not need a separate computer sitting beside the telescope if you build the system around iMate. You will still use another device to access and configure the onboard computer remotely, but the imaging applications themselves run inside the mount.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I have to use iMate?\u003c\/strong\u003e\u003cbr\u003e\nNo. The HAE43B can also be controlled directly through USB-C using an external computer and compatible ASCOM or INDI software.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it have an ST-4 autoguider port?\u003c\/strong\u003e\u003cbr\u003e\nYes. iOptron lists an integrated ST-4-compatible autoguider port on the current HAE43B. Software-based guiding through Ekos, ASCOM, or other compatible systems is also available.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes it include iPolar?\u003c\/strong\u003e\u003cbr\u003e\nNo. iPolar is an optional accessory on the current HAE43B. The iMate software includes iPolarServer for use when a compatible iPolar camera is connected.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much can it carry?\u003c\/strong\u003e\u003cbr\u003e\niOptron rates the HAE43B for 44 lb (20 kg) without a counterweight and up to 55 lb (25 kg) with the optional counterweight system. The rating assumes the payload center of gravity is approximately 200mm from the RA axis, so telescope geometry matters along with total weight.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes a tripod come with it?\u003c\/strong\u003e\u003cbr\u003e\nNo. The HAE43B is supplied without a tripod or pier, allowing you to choose the support that best matches your telescope and whether the mount will be portable or permanently installed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use it for visual observing?\u003c\/strong\u003e\u003cbr\u003e\nYes. The HAE43B can operate in Alt-Az mode for visual use as well as equatorial mode for astrophotography.\u003c\/p\u003e\n\n\u003ch3\u003eFinal Thoughts\u003c\/h3\u003e\n\n\u003cp\u003eThe HAE43B is not the encoder version of the HAE43. It is the integrated-computer version, and that gives it a very different reason to exist.\u003c\/p\u003e\n\n\u003cp\u003eYou still get the impressive part of the HAE43 platform: 44 pounds of counterweight-free payload in a mount head weighing only 12.8 pounds. What the B adds is the ability to build the rest of the imaging system around the mount itself.\u003c\/p\u003e\n\n\u003cp\u003eKStars, Ekos, INDI, onboard storage, USB connections, and accessory power are already there, allowing the camera, guider, focuser, filter wheel, and mount to become part of one compact field system.\u003c\/p\u003e\n\n\u003cp\u003eAnd because direct USB-C control remains available, choosing iMate doesn't close off the rest of the astrophotography world. Use the onboard computer when its integration makes sense. Use your own computer when you prefer another workflow.\u003c\/p\u003e\n\n\u003cp\u003eFor the imager who wants the HAE43's substantial payload but also wants fewer separate boxes and cables to carry into the field, that is the reason to choose the HAE43B.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable style=\"width:100%;
