Whether you're an amateur stargazer or a seasoned astrophotographer, an equatorial mount enhances your ability to explore the night sky with accuracy and stability.\u003c\/span\u003e\u003c\/p\u003e","products":[{"product_id":"gm-8-equatorial-mount-with-gemini-ii-go-to-computer","title":"Losmandy GM-8 Equatorial Mount with Gemini II Go-To Computer","description":"\u003cp\u003eThe Losmandy GM-8 with a Gemini II go-to computer is a well made high-precision go-to mount that is ideal for the serious visual observer\/astrophotographer who needs a highly portable mount with a 30 lb payload capacity.\u003c\/p\u003e\n\u003cp\u003eThe Losmandy GM-8 mount with a Gemini II computer system is a well-made, high-precision German equatorial mount that is very portable, but can still hold a respectable payload. It is rated at a 30 pound payload capacity, making it an excellent choice for almost every 4\" refractor, most 6\" Maksutov-Cassegrains and Maksutov-Newtonians, and even some 5\" refractors. It comes standard with a Gemini II computer and dual axis drive system whose built-in drive corrector includes periodic error correction, making it an excellent photographic platform for the serious astrophotographer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Losmandy GM-8 equatorial head:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll parts are machined from stainless steel or aluminum.

Right ascension and declination shafts are precision-machined of 1.250\" diameter aluminum. The 180 tooth main drive gear is machined of 2.812\" diameter 7075 aluminum. The heat-treated and ground stainless steel worm is in a dual supported ball bearing housing. There is a one-knob design variable slip clutch on each axis. The drive uses a 160 oz\/in stepper motor, with 1.0 arc second steps.\u003c\/p\u003e\n\u003cp\u003eThe unique fully-locking tangent arm design altitude adjustment allows use over a 0-64 degree latitude range. There is a single large adjustment knob for easy alignment. The latitude scale is laser engraved in 2 degree increments. The two-knob azimuth control provides a +\/- 8.5 degree adjustment range and positive locking.\u003cbr\u003e3.500\" diameter laser engraved setting circles are marked in 6 minute increments in right ascension and 2 degree increments in declination. The right ascension circle is engraved for both Northern and Southern Hemisphere use. The r. a. circle is a Porter slip ring design, so that when the mount is moved manually, or driven electronically, the r. a. circle follows the stars with no need to be reset periodically.\u003c\/p\u003e\n\u003cp\u003eA dovetail saddle that can accept both Losmandy D-plate and Vixen-style OTA dovetails allows for the fast interchanging of tube assemblies. Its range of fore and aft adjustment reduces the need for declination weights. The stainless steel counter weight shaft is removable and has a safety knob. The payload capacity is 30 lbs. The equatorial head weighs 21 lbs., exclusive of counterweight(s). The mount comes with one 7 lb. counterweight standard. Additional 11 lb. and 21 lb. counterweights are available to balance heavy payloads.\u003c\/p\u003e\n\u003cp\u003eAn optional illuminated through-the-axis polar alignment scope works in both Northern and Southern Hemispheres.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Losmandy GM-8 tripod:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe tripod is made of all machined aluminum, black anodized. Fold-up design for easy transporting. The tripod height is adjustable from 27\" to 43\". All heights are to the top of the tripod. Add 15\" (at a latitude of 34 degrees) to account for the distance from the top of the tripod to the top of the saddle. This total will give you the distance from the ground to the underside of the telescope optical tube. The tripod weighs 15 lbs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Losmandy GM-8 Gemini II go-to dual-axis electronics:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Losmandy Gemini 2 system is a DC servo motor-based go-to computerized positioning system. The upgraded Maxon DC servo motors supplied with the Gemini 2 have higher torque through their entire range of tracking and slewing speeds than the motors on standard Losmandy mounts that don’t have a go-to capability. The drive system has a dual 12~18V DC input\/output and draws 3.0A maximum.\u003c\/p\u003e\n\u003cp\u003eThe servo motors used in the Gemini 2 have two main advantages over the stepper motors normally used in scopes. First, servo motors run with a continuous smooth rotation, rather than the discrete short steps taken by stepper motors. This results in less image “jitter” in extremely high magnification planetary observing and stars that are tighter and more point-like in critical astrophotography applications. Second, servo motors have very high torque, even at high slewing speeds. As a result, the Gemini 2 system can deliver a maximum slew rate of approximately 6 degrees per second with the GM-8 mount.\u003c\/p\u003e\n\u003cp\u003eThe Gemini 2 computer is a stand-alone system, with no PC required for operation in the field. A full-color graphic touch screen on the hand control of the Gemini 2 system clearly displays all functions. There is a classic four-button diamond pattern for guiding, centering, moving, and slewing on both the touch screen on the front of the computer and on a tactile four-button membrane on the rear. There is also support for the original Gemini four-button controller.\u003c\/p\u003e\n\u003cp\u003eThe Gemini 2 has 0.5 arc second positioning accuracy during go-to operation. It is GPS-compatible with an optional #LGPSG2 receiver. It has Ethernet 10\/100 with full IP function to permit operation from anywhere using a browser, ASCOM, or an application over the web or serial port. There is also custom mount support using a programmable gear rate function.\u003c\/p\u003e\n\u003cp\u003eThe more than 40,000 object memory of the Gemini 2 is non-volatile and the system contains a real-time clock. You can select from English, French, Spanish, and German language displays. There are two USB ports; one for virtual COM to PC, and one for an ASCOM or planetarium program. There is PEC correction built in and an auto-guider port. The firmware can be upgraded via the internet. There are ports for future high-resolution encoders and a multi-function A\/D I\/O serial port.\u003c\/p\u003e\n\u003cp\u003eThe following databases, comprising about 41,000 stars and objects, are built into the Gemini 2 system, more than enough to keep even the most avid observer busy for some time! You get the Messier catalog (110 objects), the revised NGC catalog (7840 objects), the revised IC catalog (5386 objects), the Sh2 Sharpless 2 catalog (313 objects), a catalog of 167 bright stars, and a 17,635 star catalog of SAO stars.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable class=\"table\" id=\"product-attribute-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e1 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Losmandy","offers":[{"title":"Default Title","offer_id":40221641310281,"sku":"GM8GT","price":2745.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/gm8-1.jpg?v=1662966937"},{"product_id":"celestron-cgem-ii-computerized-equatorial-mount-40-lb-payload-capacity-91523","title":"Celestron CGEM II Computerized Equatorial Mount, 40 lb. Payload Capacity 91523","description":"\u003cp\u003eThe 40 pound payload capacity Celestron CGEM II is a high performance fully-computerized go-to mount with a 40,000 star and object memory at a price that's easy to handle.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe Celestron CGEM II is an upgraded heavy-duty computerized go-to German equatorial mount. The ergonomically-designed CGEM II has a fresh, attractive, bold appearance – and a 40 pound payload capacity. This allows it to carry Celestron SCT optical tubes up to 11\" in aperture, plus a full load of imaging accessories, as well as virtually any other optical tube and accessory payload less than 40 pounds in weight.\u003c\/p\u003e\n\u003cp\u003eThe CGEM II mount head contains dual-axis slewing\/tracking motors on each axis for go-to computer control. Steel worm gears and 90mm diameter brass worm wheels assure long-term reliability and high accuracy performance. The use of low cog DC Servo motors with integrated optical positioning encoders offers smooth, quiet operation and precision slewing and tracking. The motor armatures are skewed to minimize cogging for precise jitter-free low speed tracking. The motor drives and their wiring are all internal, keeping them snag-free and free from dust and debris.\u003c\/p\u003e\n\u003cp\u003eThe mount requires a minimum 1.5 amp 12 VDC power supply to operate. The maximum 1.5 amp power draw happens only briefly when accelerating to, or decelerating from, the high speed slewing mode from a standing start with a small payload (8\" SCT OTA or similar). Normal power draw with a well-balanced payload is generally less than half the maximum draw.\u003c\/p\u003e\n\u003cp\u003eThe mount comes with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12V battery pack. The 17 amp hour capacity Celestron Power Tank #4517V is recommended and will operate the mount all night long without danger of running out of power. An optional Celestron #2338PRO 5 amp ac adapter is available to run the CGEM II all night from household AC in backyard or observatory.\u003c\/p\u003e\n\u003cp\u003eTo make a casual polar alignment for visual use quick and easy, there's a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. No polar alignment finderscope is available to aid in the precise polar alignment required for long exposure astrophotography, nor is any needed. A unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise computerized polar alignment in mere minutes, using any bright star, even when Polaris is hidden by trees or buildings. It works in both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eThe supplied 17 pound counterweight is locked in place on the steel counterweight shaft with a single hand-tighten knob, making it easy to rebalance a scope if you add heavy photographic accessories. If needed, optional counterweights are available to balance very heavy loads.\u003c\/p\u003e\n\u003cp\u003eFor observing or imaging objects near the meridian (the imaginary line passing directly overhead from North to South), the CGEM II is designed to track well past the meridian for uninterrupted imaging through the most ideal part of the sky.\u003c\/p\u003e\n\u003cp\u003eThere are nine motor drive speeds: 0.5x and 1x sidereal for guiding; 4x, 8x, 16x, and 64x for centering; and 1°, 2°, and a fast 5° per second for slewing. Preset tracking rates include sidereal, solar, and lunar. Equatorial tracking modes are available for both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eThe supplied NexStar computer hand control has a built-in database of more than 40,000 stars and objects. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; selected variable stars; non-planetary solar system objects; and asterisms.\u003c\/p\u003e\n\u003cp\u003eYou can also store and edit the right ascension and declination of 400 additional user-defined objects of your own choosing, such as the comet and asteroid coordinates published monthly in \u003cem\u003eAstronomy\u003c\/em\u003e and \u003cem\u003eSky \u0026amp; Telescope\u003c\/em\u003e magazines. The computer control can find any of those objects with only a few keystrokes, and track them with high accuracy for visual or photographic applications. There is enhanced information on over 200 of the most note-worthy objects.\u003c\/p\u003e\n\u003cp\u003eThe NexStar computer control of the smooth and precise CGEM II go-to mount makes finding over 40,000 stars and objects easy and automatic, so you can spend more time looking at them, rather than looking for them.\u003c\/p\u003e\n\u003cp\u003eNew for the CGEM II mount, a USB 2.0 communication port on the hand control allows you to operate the telescope via a personal computer using a USB cable and NexRemote software CD-ROM. The hand control and motor control software is flash-upgradeable to allow you to download the latest product updates over the Internet to keep your CGEM II mount always at the cutting edge of technology. An autoguider port is located on the electronic pier for guided, but unattended, long exposure astrophotography.\u003c\/p\u003e\n\u003cp\u003eThe NexStar hand control provides a constant digital r. a. and dec readout of the scope's position on the sky. This provides much greater accuracy than conventional manual setting circles for star-hopping or locating objects by their celestial coordinates alone, should you want to observe the old-fashioned way without using the computer to find objects for you.\u003c\/p\u003e\n\u003cp\u003eThe software built into the NexStar hand control includes mount calibration, database filter limits, hibernate, five alignment procedures, user-defined slew limits, a new \"All-Star\" polar alignment routine that uses any bright star for a quick and accurate polar alignment, and more. Built-in adjustable backlash compensation permits precise corrections during astrophotography and when observing visually at high powers. A high precision pointing subroutine in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope.\u003c\/p\u003e\n\u003cp\u003eThe software includes permanent programmable periodic error correction (PEC) to correct for the minor periodic tracking errors inherent to all worm drives that might otherwise mar your long exposure photographs. The CGEM II mount retains the PEC recordings when it is powered down. The hand control and motor control software is flash-upgradeable to allow you to download the latest product updates over the Internet to keep your CGEM II mount always at the cutting edge of technology.\u003c\/p\u003e\n\u003cp\u003eAn autoguider port is located on the electronic pier for long exposure astrophotography. The autoguider port can use a six-pin RJ-12 modular jack ST-4 compatible CCD autoguider to automatically control the drive motors during long exposure astrophotography.\u003c\/p\u003e\n\u003cp\u003eFive different alignment methods are built into the NexStar computer - 2-star align, quick align, 1-star align, last alignment, and solar system align - allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. Alignment is easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take your CGEM II-mounted scope outdoors.\u003c\/p\u003e\n\u003cp\u003eIn addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive SkySync GPS module) for full GPS (Global Positioning System) satellite accuracy. Adding GPS to the computer is something no competitively-priced mount can do. Once the scope is approximately polar aligned, the 16-channel SkySync GPS system uses signals from government satellites to calculate the scope's location on earth with an accuracy measured in meters. The system also calculates the current time based on the split second accuracy of the GPS time signals.\u003c\/p\u003e\n\u003cp\u003eAfter the SkySync quickly completes these calculations and enters the information into the computer control for you automatically, the computer can then orient the scope with the sky, slew to a pair of guide stars, ask you to confirm that the stars are in the center of the field (and center them if they're not precisely aligned), and then start finding and tracking over 40,000 objects for you at your command. With the CGEM II go-to mount and the SkySync, orienting your scope in time and space on earth and aligning it on the sky becomes almost as easy a task as simply turning the mount on.\u003c\/p\u003e\n\u003cp\u003eThe adjustable height tripod has 2\" diameter stainless steel legs with a metal center leg brace for rigidity to provide excellent damping characteristics. The center leg brace is drilled to form a convenient accessory tray that holds 1.25\" and 2\" eyepiece to keep them up out of the dew-soaked grass.\u003c\/p\u003e\n\u003cp\u003eNew for the CGEM II mount is a dual saddle plate. The saddle plate will now accept both the CGE\/Losmandy wide dovetail plate as well as the AVX\/Vixen style dovetail plate. The dovetail slot on the top of the mount holds the long dovetail slide bar mounted under the optical tube. This allows you to slide the optical tube fore and aft in the dovetail slot to quickly and precisely balance the optical tube in declination when you add or subtract accessories, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and takedown times are exceptionally fast, as a single large hand-tighten knob holds the optical tube in place. A second lock knob prevents the tube from sliding off the mount should the hand-tighten knob loosen. The oversized dovetail mounting platform assures secure vibration-free tube attachment.\u003c\/p\u003e\n\u003cp\u003eThe CGEM II mount weighs 75 pounds. The equatorial head is the heaviest component, at 41 pounds. The tripod weighs 19 pounds, as does the single supplied counterweight. Optional 11 lb. and 17 lb. counterweights are available to balance heavy payloads.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable class=\"table-open\" id=\"product-specs-list\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMount Type:\u003c\/td\u003e\n\u003ctd\u003eComputerized Equatorial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstrument load capacity:\u003c\/td\u003e\n\u003ctd\u003e40 lbs (18 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight adjustment range (includes mount and tripod):\u003c\/td\u003e\n\u003ctd\u003e1346mm -

It is more stable because the center of gravity is directly over the center of its base. It is more portable because it can be broken down into smaller component parts than a fork-mount telescope for easier storage and transportation. As for being universally adaptable, it can be used with physically long refractors and reflectors as well as short-tube catadioptric scopes.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/3Nzf-Ava6OM\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"autoplay; encrypted-media\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eFor astrophotography, the German equatorial mount offers easier balancing; unlimited space at the rear of the telescope tube to mount a long camera equipment train that can't bump into the drive base, as is the case with many fork-mounted scopes; and whole sky access that many fork-mounted scopes can't achieve.\u003c\/p\u003e\n\u003cp\u003eFor German equatorial mount lovers and serious astrophotographers, Celestron has developed this new 75 pound payload capacity CGX-L equatorial mount and tripod.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeavy duty mount head:\u003c\/strong\u003e The Celestron CGX-L is a newly-designed high payload capacity\/high precision go-to German equatorial mount that epitomizes all of these German equatorial mount virtues. With its full 75 pound payload capacity it will carry Celestron SCT\/HD optical tubes up to 14\" in aperture, as well as virtually any other optical tube and accessory payload weighing up to 75 pounds.\u003c\/p\u003e\n\u003cp\u003eNew features are everywhere in the Celestron CGX-L mount head. It has ergonomic handles that help you move the 47 pound head with ease. That's right; the head weighs only 47 pounds, but will carry 75, an incredible load to weight ratio.\u003c\/p\u003e\n\u003cp\u003eIn addition to the standard auxiliary ports in the mount head, additional accessory ports are built into the dovetail saddle plate of the equatorial head. There are two auxiliary ports as well as an autoguider port. The internal cabling of the CGX-L mount works hand in hand with these new ports on the saddle helping the imager in all of us manage our cables.\u003c\/p\u003e\n\u003cp\u003eThe dovetail saddle plate is longer for added stability and accepts both Vixen\/AVX and Losmandy\/Celestron D Style dovetails.\u003c\/p\u003e\n\u003cp\u003eThere are built-in home and limit sensors. The home sensor takes the scope back to its home position at any time and the limit sensor prevents the mount from slewing past a certain point. Built-in mechanical hard stops protect your scope from damage should you forget to lock the mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMount drive system:\u003c\/strong\u003e The CGX-L mount head contains 144mm worm wheels in both right ascension and declination. The improved drive system uses a belt-driven spring-loaded worm gear. This allows the drive to maintain optimum gear mesh for smoother tracking and less backlash.\u003c\/p\u003e\n\u003cp\u003eThe mount requires 2.5 Amp 12 VDC power to operate. The maximum 2.5 amp power draw happens only briefly when accelerating to the high speed slewing mode from a standing start. Normal power draw with a well-balanced payload is generally considerably less than half the maximum draw. The mount comes with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12 VDC battery pack. The 17 amp hour capacity Celestron Power Tank\u003cbr\u003e#4517V is recommended and will operate the mount all night long without danger of running out of power. The Celestron #2338PRO ac adapter will let you operate the mount from household AC power for backyard and observatory use.\u003c\/p\u003e\n\u003cp\u003eSpecially designed power management electronics deliver constant regulated power to the motor so that it is capable of driving the mount even when your scope not perfectly balanced. This allows your CGX-L to have the payload capacity of that of much larger (and more expensive) mounts without sacrificing smooth tracking motion and pointing accuracy across the entire sky.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolar alignment:\u003c\/strong\u003e To make a casual no-tool polar alignment for visual use quick and easy, there's a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. If serious long exposure astrophotography is in your plans, the special All-Star Polar Alignment software described below allows you to choose any bright alignment star for a software-assisted alignment of the mount's polar axis, even if you can't see the North Star. The mount also has upgraded adjustments for latitude and azimuth. Large one hand knobs make moving a fully-loaded mount head easy with a simple twist of the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCounterweight:\u003c\/strong\u003e The CGX-L mount comes with one 22 pound counterweight.The counterweight locks in place on the 5 pound steel counterweight shaft with a single hand-tighten knob, making it easy to rebalance your scope in right ascension if you add heavy photographic accessories. If needed, optional counterweights are available to balance very heavy loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeavy duty tripod:\u003c\/strong\u003e The CGX-L mount's adjustable height Super HD tripod has 2.75\" diameter stainless steel legs. The height adjustment leg locks are on the inside of the tripod legs to keep them from snagging on clothing in the dark. The tripod uses a dual leg support for maximum rigidity, with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension. The upper leg brace forms a convenient tray that holds eyepieces and accessories, as well as a slot to hold your smart phone or tablet, to keep them up out of the dew-soaked grass. This tray is a new design that will allow you to keep it attached while you fold the legs up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMounting an optical tube:\u003c\/strong\u003e Optical tubes are installed on the CGX-L mount using a slot on the mount head that accepts a Celestron CGE-style\/Losmandy D-plate dovetail or a Celestron AVX\/CG5\/Vixen slide bar. This allows the optical tube to be quickly and precisely balanced fore and aft on the mount in declination, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and take downtimes are exceptionally fast, with large hand-tighten knobs holding the optical tube in place.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/KLRzVoXpPaE\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"autoplay; encrypted-media\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMount weight:\u003c\/strong\u003e The CGX-L mount weighs in at 121 pounds. The equatorial head and thread-in counterweight shaft total 52.6 pounds. The tripod weighs 46.2 pounds. The supplied counterweight weighs 22 pounds. The new ergonomic handles on the mount head make it much easier for a single person to move and break down the mount in the field with ease.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNexStar computer hand control:\u003c\/strong\u003e The NexStar computer hand control of the CGX-L mount has a built-in database of more than 40,000 stars, deep space objects, and solar system objects it can locate for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable stars; non-planetary solar system objects; and asterisms. It contains enough fascinating objects to keep you busy observing for the rest of your life.\u003c\/p\u003e\n\u003cp\u003eYou can also store and edit the right ascension and declination of 100 objects of your own choosing, such as the comet and asteroid coordinates published monthly in Astronomy and Sky \u0026amp; Telescope magazines.The computer control can quickly find any of those objects at your command, and track them with high accuracy for visual observing or astrophotography.\u003c\/p\u003e\n\u003cp\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. This display leads you through the steps necessary to line up the scope on the sky, locate objects, control scope functions like the brightness of the hand control display, and much more. It shows you basic information about the object being viewed (such as the object's name, catalog designation, type, magnitude, and so forth). In addition to this basic information, there is enhanced information on over 200 of the most note-worthy objects. The display can also show you the right ascension and declination coordinates at which the scope is aimed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlignment on the sky and go-to accuracy:\u003c\/strong\u003e No polar alignment finderscope is available for the CGX-L mount, nor is any needed. A unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise polar alignment in mere minutes for long exposure astrophotography, even if the celestial pole is hidden by trees. It works in both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eAlthough the telescope's tracking may be very good after alignment, pointing accuracy may need to be improved (particularly if you are trying to located small objects on a CCD chip), depending on how close your initial mechanical alignment was on the pole, and by much the mount had to be moved during polar alignment. If that's the case, you can easily update your telescope's star alignment in a minute or two if necessary.\u003c\/p\u003e\n\u003cp\u003eOnce polar aligned, several different sky alignment methods are built into the NexStar computer to line up the scope on the celestial sphere, allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. These include 2-Star Align, Solar System Align, Last Alignment, Quick Align, and 1-Star Align,\u003c\/p\u003e\n\u003cp\u003eWith just a standard hand control alignment, the CGE Pro computer has the ability to center a star in your telescope's eyepiece or on a CCD chip to within 5 arc minutes. Using the NexStar computer's advanced pointing features (such as Calibration Stars, Sync, and Precise Go-To) further improves the pointing accuracy to as low as 1 arc minute in the desired region of the sky. The high precision pointing subroutine (Precise Go-To) in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope. Other software features include: database filter limits, amount hibernate mode, and user-defined slew limits. The Celestron CGX-L comes with Celestron's new PWI telescope control software, co-developed by PlaneWave Instruments, that features multi-point mount modeling for extremely precise pointing accuracy.\u003c\/p\u003e\n\u003ch2\u003eTech Details:\u003c\/h2\u003e\n\u003ctable class=\"table-open\" id=\"product-specs-list\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMount Type:\u003c\/td\u003e\n\u003ctd\u003eComputerized Equatorial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstrument load capacity:\u003c\/td\u003e\n\u003ctd\u003e75 lbs (34 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight adjustment range (includes mount and tripod):\u003c\/td\u003e\n\u003ctd\u003e1524mm - 1955.8mm (60\" - 77\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTripod adjustment range (tripod only):\u003c\/td\u003e\n\u003ctd\u003e838.2mm - 1397mm (33\" - 55\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEquatorial height alone:\u003c\/td\u003e\n\u003ctd\u003e609.6mm (24\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTripod Leg Diameter:\u003c\/td\u003e\n\u003ctd\u003e69.85mm (2.75\") Steel tripod with graduated markings on lower section\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLatitude adjustment range:\u003c\/td\u003e\n\u003ctd\u003e3° - 65°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMount Head Weight:\u003c\/td\u003e\n\u003ctd\u003e52.6 lbs (23.8 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccessory Tray:\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTripod Weight:\u003c\/td\u003e\n\u003ctd\u003e46.2 lbs (21 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight of Counterweights:\u003c\/td\u003e\n\u003ctd\u003e1 x 22 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSlew Speeds:\u003c\/td\u003e\n\u003ctd\u003e9 slew speeds - max speed 3°\/second\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTracking Rates:\u003c\/td\u003e\n\u003ctd\u003eSidereal, Solar and Lunar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTracking Modes:\u003c\/td\u003e\n\u003ctd\u003eEQ North and EQ South\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGPS:\u003c\/td\u003e\n\u003ctd\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDovetail Compatibility:\u003c\/td\u003e\n\u003ctd\u003eDual saddle plates (CG-5 and CGE saddle)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Auxiliary Ports:\u003c\/td\u003e\n\u003ctd\u003e4 AUX Ports (Hand Control can use any AUX Port, 2 are located near the dovetail saddle for optional accessories)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutoguide Port:\u003c\/td\u003e\n\u003ctd\u003eYes, 2 Ports (one is located near the dovetail saddle)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUSB Port:\u003c\/td\u003e\n\u003ctd\u003eYes, input for Mount and Hand Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Requirements:\u003c\/td\u003e\n\u003ctd\u003e12V DC, 3 amps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Drive:\u003c\/td\u003e\n\u003ctd\u003eDC servo motors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlignment Procedures:\u003c\/td\u003e\n\u003ctd\u003e2-Star Align, 1-Star Align, Solar System Align, Last Alignment, Quick Align\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePeriodic Error Correction:\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComputerized Hand Control:\u003c\/td\u003e\n\u003ctd\u003e2 line x 18 character backlit Liquid Crystal Display, 19 LED backlit buttons, USB 2.0 Port for PC connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNexStar+ Database:\u003c\/td\u003e\n\u003ctd\u003e40,000+ objects, 100 user defined programmable objects.

It may well be the only go-to German equatorial mount you'll ever need for visual observing and critical astrophotography.\u003c\/p\u003e\n\u003cp\u003eThe industry-standard Losmandy G-11 is a rock solid visual and photographic tracking equatorial mount that can hold an instrument payload of up to 60 pounds. While not the most portable mount in the world, weighing in at 102 pounds with its 21 lb counterweight, it can generally be taken down and set up rather easily by one person, as the heaviest single component (the folding tripod) weighs only 45 lbs. This mount has excellent drive smoothness and accuracy, plus programmable periodic error correction, and is well-suited for astrophotography.\u003c\/p\u003e\n\u003cp\u003eThe inclusion of the Losmandy Gemini II go-to hand-held high torque servo-based computer system turns the G11 into a full go-to computerized mount.

The control electronics have the typical Losmandy hallmarks of being fully machined, anodized and brushed, with beautifully radiused edges that look like part of a Losmandy system, rather than a third party bolt-on. The new full-color graphic touch screen on the hand control clearly displays all functions. It has the classic four-button Gemini pattern for guiding, centering, moving, and slewing on both the touch screen and on a tactile four-button membrane on the rear of the hand control.\u003c\/p\u003e\n\u003cp\u003eThe Gemini II feature set is comprehensive, making the system ideal for both casual observing and serious research. The system has been thoroughly tested in both Northern and Southern Hemispheres, and has been designed for precise and dependable use.\u003c\/p\u003e\n\u003cp\u003eThe heavy duty folding tripod allows the tripod head and legs to be stored and carried as a single unit, rather than the tripod head and three separate legs of the standard G-11 tripod, which must be assembled each time the mount is set up. This folding tripod version of the G-11 makes regular transport of the mount to a dark sky site and set-up easier than the standard non-folding tripod version, which may be more suited to a permanent observatory location.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEQUATORIAL HEAD SPECIFICATIONS \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMade of machined aluminum and stainless steel, black anodized.\u003c\/li\u003e\n\u003cli\u003eAll stainless steel hardware.\u003c\/li\u003e\n\u003cli\u003eOne 3.750\" diameter needle thrust bearing.\u003c\/li\u003e\n\u003cli\u003eOne 2.000\" diameter needle thrust bearing.\u003c\/li\u003e\n\u003cli\u003eTwo 1.500\" diameter needle bearings.\u003c\/li\u003e\n\u003cli\u003e5.625\" diameter, 360 tooth, 7075 aluminum worm gear.\u003c\/li\u003e\n\u003cli\u003eDual supported, ball bearing housed, stainless steel worm that has been heat treated and ground for precision and accuracy.\u003c\/li\u003e\n\u003cli\u003eVariable slip clutch, both axes.

These include scopes ranging in size from a 4\" f\/10 refractor up to a 6\" f\/5 refractor and a 6\" f\/5 Newtonian reflector (up to a maximum payload of 20 lbs).\u003c\/p\u003e\n\u003cp\u003eThe Celestron CG-4 mount does not come with a motor drive as standard equipment, but its manual worm gear drive slow motion controls will let you smoothly track celestial objects for visual observing with only an occasional twist of the wrist. Adding optional dual axis motor drive #MDCG4D will keep objects centered in the eyepiece continuously. If family viewing is planned, a motor drive means you don't have to worry about the object being observed drifting out of view while changing observers. This is especially handy when observing with small children or groups of people (at star parties or scout meetings, for example). If astrophotography is in the cards, the #MDCG4D motor drive\/drive corrector is essential.\u003c\/p\u003e\n\u003cp\u003eThe Celestron CG-4 mount uses precision ball-bearings in both the right ascension and declination axes to assure smooth and hitch-free motion of your scope across the skies. Built-in non-powered setting circles are provided to help you find objects by using their right ascension (hour) and declination (degree) coordinates as shown in a star chart or atlas. The right ascension hour circle is equipped with a vernier scale that lets you adjust the telescope position in right ascension to an accuracy of one arc minute.\u003c\/p\u003e\n\u003cp\u003eThe standard manual right ascension and declination slow motion controls have easy-grip knobs that make manual tracking and small position adjustments a cinch. The extra-large control knobs are positioned so that they fall easily to hand when observing, so you don't have to grope blindly for the knobs when you need to make adjustments to the scope's position.\u003c\/p\u003e\n\u003cp\u003eTo make a casual polar alignment for visual use quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. The mount can be used over a latitude range of approximately 20° to 60°. If astrophotography is in your plans, an optional polar finder #3912 is available to increase the accuracy of your alignment.\u003c\/p\u003e\n\u003cp\u003eThe mount's adjustable height tripod has 1.75\" diameter stainless steel legs for strength and rigidity. There's a center leg brace that locks the tripod legs firmly in place for excellent vibration-damping. The center brace is drilled with several holes that will hold your 1.25\" and 2\" eyepieces conveniently at hand and up and out of the dew-soaked grass. The no-tool locking knobs that adjust the height of the tripod are located on the inside of the tripod legs. This keeps them from snagging clothing in the dark, a thoughtful touch sure to be appreciated. The tripod adjusts over a height range of 33\" to 47\". As with all tripods, it is at its most rigid and stable when at its lowest height.\u003c\/p\u003e\n\u003cp\u003eTwo counterweights totaling 11 pounds (one 7 lb. and one 4 lb.) are supplied to balance the optical tube. The sliding counterweights are locked in place with a single hand-tighten thumbscrew each, making it easy to rebalance the scope as you add and remove accessories.\u003c\/p\u003e\n\u003cp\u003eA Vixen-style dovetail slot in the CG-4 head allows an optical tube using an optional Vixen-style dovetail to be quickly and precisely balanced fore and aft on the mount, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and takedown times are exceptionally fast, as no tools are required to assemble the mount and tripod and only a single large hand-tighten knob holds an optical tube in place. A second smaller lock knob prevents the tube from sliding off the mount should the hand-tighten knob loosen.\u003c\/p\u003e\n\u003cp\u003eThe CG-4 equatorial head weighs 10 lbs (4.5 kg). The 7 lb (3.2 kg) and 4 lb (1.8 kg) counterweights total 11 lbs (5 kg). The tripod weighs 12.5 lbs (5.7 kg). Total weight of the complete mount set up to receive an optical tube is 33.5 lbs (15.2 kg).\u003c\/p\u003e\n\u003cp\u003eThe CG-4 mount is protected by Celestron's two-year warranty.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e33.5 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":40221671325769,"sku":"CG-4","price":419.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/19034.jpg?v=1662967933"},{"product_id":"software-bisque-paramount-mx-heavy-duty-robotic-german-equatorial-mount-90-lb-payload","title":"Software Bisque Paramount MX Series 6 Heavy Duty Robotic German Equatorial Mount, 90 Lb Payload","description":"\u003cp\u003eThis Software Bisque Paramount MX Series 6 heavy duty robotic German equatorial mount has 90 pound payload capacity and a broad range of advanced features and capabilities that will keep you focused on the Universe and not your equipment.\u003c\/p\u003e\n\u003cdiv class=\"heading\"\u003eThis Software Bisque Paramount MX Series 6 robotic German equatorial mount has . . .\u003c\/div\u003e\n\u003cdiv class=\"heading\"\u003e\n\u003cul\u003e\n\u003cli\u003e125 lb.

The mount head, less counterweights, weighs only 50 pounds, making the Paramount MX Series 6 truly field portable. The 7.5\" 375 tooth aluminum right ascension and declination gears combine with precision brass worms to provide a maximum periodic error of a mere seven arc seconds peak-to-peak - even before periodic error correction is used. When periodic error correction is applied, the resulting peak-to-peak error can be reduced to approximately one arc second or less.\u003c\/p\u003e\n\u003cp\u003eBoth the right ascension and declination axes have a simple three position mechanical \"switch\" to engage the worm during normal operation, disengage the worm from the gear when balancing the payload, or lock the axis during transit. The right ascension and declination axes are supported by 6-inch contact ball bearings. All cables and motors are inside the body of the mount, and through-the-mount access holes allow you to add your own internal cables. A 45 arc minute bubble level is built into the mount for accurate leveling in the field.\u003c\/p\u003e\n\u003cp\u003eA Paramount MX-style Versa-Plate for attaching optical tube assemblies is standard equipment, as is a 16-in. (41 cm) counterweight shaft and two 20 lb (9 kg) counterweights. The Paramount MX can be used over a 10 to 65 degree latitude range. The azimuth adjustment range is +\/- 3.5 degrees. The altitude and azimuth polar alignment knobs are calibrated, so that making adjustments using the supplied TPoint Polar Alignment Report software is simple and very accurate.\u003c\/p\u003e\n\u003cp\u003eA universal AC power supply included. It can be used with any 100-240VAC source, from 47 to 63 Hz, and draws a maximum 1.9A. The DC output to the mount is 48V, with a 1.66A maximum draw. The instrument panel has one 12V and one 5V power port on the mount's instrument panel to supply power to your observing equipment. There is a built-in autoguider port and focuser port on the instrument panel.\u003c\/p\u003e\n\u003cp\u003eTwo brushless DC servomotors are used to drive the scope. If your mount is used for survey astronomy all night, every clear night, no other type of motor is sufficient. Other commercial mounts use \"brushed motors\" that don't have nearly the life expectancy of brushless DC servomotors and are not designed to be operated for long periods at the (relatively slow) sidereal rate. The Paramount MX uses single-reduced belt-driven worms to assure backlash so small (typically less than two arc seconds in both axes) that it is difficult to measure. Autoguiding calibration is always a snap with this \"no-slop\" system. Spur gears and other components that may introduce backlash are not used.\u003c\/p\u003e\n\u003cp\u003eThe DC servomotors provide fast slew speeds and consistent torque at all slew rates. The maximum slew and tracking rate is six degrees per second in both right ascension axis and declination (the default slew rate is 5.4 degrees per second). A temperature-compensated internal oscillator with better than 10 parts per million accuracy ensures accurate tracking rates over a wide temperature range. There is also a built-in temperature sensor that allows the slew rate to be automatically reduced when the temperature drops.\u003c\/p\u003e\n\u003cp\u003eThe gear-reducer and worm-block design of the Paramount MX are extremely efficient, so that little power is lost between the motor and the telescope drive. Though good balance is always recommended, the Paramount MX has no problem slewing or tracking even when several foot-pounds out of balance. You'll spend less time fiddling with the telescope and more time acquiring data with the Paramount MX Series 6.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdvanced electronics:\u003c\/strong\u003e The Paramount MX Series 6 includes Software Bisque's fourth generation dual axis telescope control system. \u003c\/p\u003e\n\u003cp\u003eThe position of the motors is monitored 3333 times each second to ensure optimal tracking accuracy and smooth, consistent slewing at all rates and all times. Tracking and \"in progress slews\" are immediately stopped in the event the mount's payload encounters a fixed object, such as the side of the pier. Slewing and tracking rates can be configured with 56-bit precision. That means that the right ascension and declination motors can be rotated at 0 to 4000 revolutions per minute and virtually anywhere in between. This provides very precise tracking and slewing, with the ability to track comets, asteroids, and even fast- or slow-moving objects such as low earth orbit satellites or any object that moves above or below the sidereal rate.\u003c\/p\u003e\n\u003cp\u003eThe supplied hand control features an integrated mini-joystick control and configurable rate, a five-position switch that allows single-handed mount control, an integrated bright red LED flashlight, a sturdy \"hang anywhere\" cable loop, and a 15-foot coiled hand control to mount cable.\u003c\/p\u003e\n\u003cp\u003eProgrammable periodic error correction with \"seeing agnostic\" periodic error curve fitting is built into TheSkyX Professional Edition software supplied with the Paramount MX. AutoHome™ homing capability (to better than one arc second resolution with built-in sensor circuitry on each axis) ensures that the mount always knows its orientation (after an initialization process called \"homing\"), even after power failure. There is a configurable park position for operation in a remote location dome. There is a soft \"reboot\" capability. This means that the control system can be restarted through software and does not have to be manually turned off, then on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSupplied software:\u003c\/strong\u003e The Paramount MX Series 6 comes with the world's best and most powerful astronomy suite of astronomy software. \u003cmeta charset=\"utf-8\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eParamount’s unsurpassed pointing and tracking performance is made possible by its integrated\u003cspan\u003e \u003c\/span\u003eTPoint™ modeling and ProTrack™ technologies.

It's an ideal platform for beginning and intermediate DSLR and CCD imagers, as it has the imaging-friendly features of Celestron's larger telescope mounts, but at a fraction of the cost of those larger mounts. For example, it has permanent periodic error correction (PPEC), an autoguider input, and the ability to image across the meridian without doing a meridian flip, so you can seamlessly image the best part of the night sky.\u003c\/p\u003e\n\u003cp\u003eExperienced imagers will love taking this portable Celestron VX mount to a dark sky site (the head weighs only 17 lbs, the tripod only 18, plus an 11 lb counterweight), as it provides all the performance of the larger Celestron observatory mounts in a portable package. If you're new to imaging, the Celestron Advanced VX mount will help you get started with the hobby and keep up with your needs for years to come.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures of the AVX mount:\u003c\/strong\u003e The mount includes dual-axis slewing\/tracking low-cog DC servo motors with positioning encoders on each axis for go-to computer control. The new motors provide improved tracking performance and more power to handle an unbalanced load than previous Advanced Series drives. Built-in adjustable backlash compensation and permanent user-programmed periodic error correction (PPEC) permits precise corrections during astrophotography and when observing visually at high powers. There are nine slewing speeds, with a fast maximum slewing rate of 4° per second. Tracking rates include sidereal, solar, and lunar.\u003c\/p\u003e\n\u003cp\u003eThe scope is supplied with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12V battery pack. The mount requires a 12VDC 3.5A power source, so the Celestron 17 amp hour capacity Power Tank #4517V is recommended for extended use in the field. The Power Tank can be recharged hundreds of times and will operate the scope all night long without danger of running out of power. Celestron AC adapter #2338PRO is also available to operate the scope from household AC in your back yard.\u003c\/p\u003e\n\u003cp\u003eA sliding 11 pound counterweight is locked in place a single hand-tighten thumbscrew. Additional optional counterweights are available, making it easy to rebalance the scope if you add heavy photographic accessories. The mount is easily capable of handling the scope and any reasonable combination of photographic accessories you might want to use. Snap-on covers keep the motor drives free from dust and debris. A set of optional vibration suppression pads #4525 under the tripod feet will improve the telescope damping time for steadier high power observing.\u003c\/p\u003e\n\u003cp\u003eTo make a casual polar alignment for visual use quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. The scope can be used over a wide 7° to 77° latitude range in both the northern and southern hemispheres.

The NexStar+ hand control offers multiple language programming (English, French, Italian, German, Spanish). There are 19 fiber optic back-lit LED buttons to make it easy for you to control the computer without affecting your dark adapted vision. There are two AUX ports, an autoguider port, and an RS-232 communication port on the hand control that allows you to operate the telescope via a personal computer. The computer hand control software can be upgraded over the Internet from Celestron's website, assuring that you always have the most current software version at your command.\u003c\/p\u003e\n\u003cp\u003eSeveral different alignment methods are built into the NexStar+ computer, allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. You can choose two-star align, quick align, one-star align, last alignment, or solar system align. Each of these computer-guided alignment methods is easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take your scope outdoors, including telescope assembly time.\u003c\/p\u003e\n\u003cp\u003eIn addition, the NexStar+ computer hand control is GPS-compatible (using an optional inexpensive SkySync GPS module) for full GPS (Global Positioning System) satellite accuracy.

The mount head, less counterweights, weighs 85 pounds, but will support an instrument payload of 240 lbs (480 lbs with counterweights), compared with the 150 lb capacity of the original Paramount ME. The 11.4\" diameter right ascension and 9.5\" diameter declination gears (on 3\" r.a. and dec shafts) combine with precision 1\" brass worms to provide a maximum periodic error of a mere seven arc seconds peak-to-peak - even before periodic error correction is used.

(The previous and highly acclaimed 150 lb payload Paramount ME used only 11 in-oz torque motors.) If your mount is used for survey astronomy all night, every clear night, no other type of motor is sufficient. Other commercial mounts use \"brushed motors\" that don't have nearly the life expectancy of brushless DC servomotors and are not designed to be operated for long periods at the (relatively slow) sidereal rate. A 200 watt AC power supply is standard equipment (compared with the 80 watt supply of the original Paramount ME).\u003c\/p\u003e\n\u003cp\u003eThe DC servomotors provide fast slew speeds and consistent torque at all slew rates.

Tracking and \"in progress slews\" are immediately stopped in the event the mount's payload encounters a fixed object, such as the side of the pier. Slewing and tracking rates can be configured with 56-bit precision. That means that the right ascension and declination motors can be rotated at 0 to 4000 revolutions per minute and virtually anywhere in between. This provides very precise tracking and slewing, with the ability to track comets, asteroids, and even fast- or slow-moving objects such as low earth orbit satellites or any object that moves above or below the sidereal rate.\u003c\/p\u003e\n\u003cp\u003eThe supplied hand control features an integrated mini-joystick control and configurable rate, a five-position switch that allows single-handed mount control, an integrated bright red LED flashlight, a sturdy \"hang anywhere\" cable loop, and a 15-foot coiled hand control to mount cable.\u003c\/p\u003e\n\u003cp\u003eThere is a configurable park position for operation in a remote location dome.

A large SCT or Ritchey-Chrétien, heavy camera, filter wheel, off-axis guider, rotator, focuser, and perhaps a second telescope can put more demand on the mount than everything else in the observatory combined.\u003c\/p\u003e\n\n\u003cp\u003eThe iOptron CEM120 is built for that kind of system. It carries up to 115 lb (52 kg) of payload, not including counterweights, on a 57 lb (26 kg) mount head. More importantly, it is designed around the things that matter once a mount becomes a permanent part of an observatory: low periodic error, large conventional worm gears, permanent periodic error correction, through-mount cabling, LAN and Wi-Fi control, automatic zero-position sensing, and enough saddle and bearing structure for large optical tubes and complex imaging trains.\u003c\/p\u003e\n\n\u003cp\u003eThis is the standard CEM120 rather than the encoder-equipped CEM120EC or EC2. It uses precision worm gearing and iOptron's Permanent Periodic Error Correction rather than high-resolution tracking encoders. For long-focal-length deep-sky work you will normally guide it, but you start with a published periodic error of less than ±3.5 arcseconds and a 240-second worm period that can be characterized and corrected very effectively.\u003c\/p\u003e\n\n\u003cp\u003eIf you are building around a C14, large RC, 6-inch-class refractor, dual-telescope system, or another imaging payload that has outgrown a mid-sized mount, the CEM120 is meant to become part of the observatory rather than something you carry outside every clear night.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e115 lb payload capacity.\u003c\/strong\u003e iOptron rates the CEM120 for 52 kg (115 lb) of telescope and imaging equipment, excluding counterweights.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e57 lb mount head.\u003c\/strong\u003e A payload-to-mount-weight ratio of roughly 2:1 for a mount intended to carry substantial observatory-class systems.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eCenter-balanced equatorial design.\u003c\/strong\u003e The CEM architecture places the system's mass closer to the center of the support structure rather than cantilevering the entire mount head to one side.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003ePeriodic error under ±3.5 arcseconds.\u003c\/strong\u003e iOptron specifies PE below ±3.5 arcseconds for the standard CEM120, measured with an encoder on the bench over its 240-second worm period.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003ePermanent Periodic Error Correction.\u003c\/strong\u003e The mount can record a PEC curve and store it in the RA motor controller for repeated playback.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e216mm worm wheels on both axes.\u003c\/strong\u003e Each axis uses a 360-tooth worm wheel driven by a 26mm worm.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eLarge steel axles and bearings.\u003c\/strong\u003e Both axes use 80mm steel shafts riding in 125mm bearings.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e0.07-arcsecond motor resolution.\u003c\/strong\u003e Precision stepper motors with 128 micro-steps provide fine commanded motion for GoTo and tracking.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e17.2-inch Losmandy-D saddle.\u003c\/strong\u003e The long saddle gives large optical tubes and long dovetail plates plenty of clamping area.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in LAN and Wi-Fi.\u003c\/strong\u003e The mount can connect directly to an observatory network without requiring a separate wireless adapter.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eUSB and RS-232 control.\u003c\/strong\u003e Direct computer connections are also available for conventional local control.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAdvanced through-mount cable management.\u003c\/strong\u003e USB, power, guide, and auxiliary connections can be routed through the mount rather than draped across moving axes.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e32-channel GPS.\u003c\/strong\u003e Supplies location and UTC information to the mount.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAutomatic zero-position search.\u003c\/strong\u003e The CEM120 can electronically locate its reference position for repeatable remote startup.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eMultiple park positions.\u003c\/strong\u003e Park horizontally, vertically, at the current position, or at user-entered altitude and azimuth coordinates.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eConfigurable meridian behavior.\u003c\/strong\u003e The mount can stop or perform an automatic meridian flip, with up to 14° of past-meridian travel available.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eST-4 autoguider port.\u003c\/strong\u003e Traditional guider input is provided in addition to software-based pulse guiding.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eOptional internal iPolar.\u003c\/strong\u003e iOptron's #3339A-120 electronic polar scope can be installed internally if you want a dedicated polar-alignment camera.\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\u003eWhy Center-Balanced?\u003c\/h3\u003e\n\n\u003cp\u003eTraditional German equatorial mounts place the right-ascension axis to one side of the tripod or pier, with the telescope on one side of that axis and the counterweights on the other.\u003c\/p\u003e\n\n\u003cp\u003eiOptron's CEM layout rearranges that geometry so the RA assembly and combined load sit more directly over the center of the support. The idea is not to eliminate counterweights — the CEM120 still uses them — but to place the total mass in a more naturally centered relationship with the pier.\u003c\/p\u003e\n\n\u003cp\u003eThat becomes increasingly useful as payloads get larger. A C14 with a full imaging train or a large RC does not just add weight; it adds leverage. Keeping as much of the system's mass as practical over the center of the pier helps the entire structure behave like one integrated observatory system instead of a large weight hanging beside it.\u003c\/p\u003e\n\n\u003ch3\u003eConventional Gearing Done on a Large Scale\u003c\/h3\u003e\n\n\u003cp\u003eThe CEM120 is not a strain-wave mount and it is not an encoder mount. It is a large precision worm-driven equatorial mount.\u003c\/p\u003e\n\n\u003cp\u003eBoth axes use 216mm diameter, 360-tooth worm wheels driven by 26mm worms. The RA worm completes one rotation every 240 seconds, giving the mount a relatively short and predictable periodic-error cycle.\u003c\/p\u003e\n\n\u003cp\u003eiOptron specifies periodic error below ±3.5 arcseconds for the standard CEM120. That figure is measured on the bench with an encoder; the production mount itself does not contain the high-resolution tracking encoders found in the CEM120EC and EC2.\u003c\/p\u003e\n\n\u003cp\u003eFor imaging, that distinction matters. The CEM120 does not internally correct its position in real time with a high-resolution RA encoder. Instead, you use its low native periodic error, Permanent Periodic Error Correction, and an autoguider as part of a conventional high-precision imaging system.\u003c\/p\u003e\n\n\u003cp\u003eFor many observatory installations, that is a very sensible arrangement. Guiding software already has access to the imaging system, the mount's periodic behavior is slow and repeatable, and PPEC can remove much of the predictable worm error before the guider has to respond.\u003c\/p\u003e\n\n\u003ch3\u003ePermanent Periodic Error Correction\u003c\/h3\u003e\n\n\u003cp\u003eThe standard CEM120 supports Permanent Periodic Error Correction rather than the real-time encoder correction used by the EC versions.\u003c\/p\u003e\n\n\u003cp\u003eDuring PEC training, the mount records corrections over one complete 240-second RA worm cycle. That correction data is then stored in the RA motor controller and remains available until you replace it with a new recording.\u003c\/p\u003e\n\n\u003cp\u003eiOptron recommends recording PEC with a guiding camera. Once a good curve has been stored, PEC playback can reduce the repeatable part of the RA tracking error while the autoguider handles the remaining slower and non-periodic errors.\u003c\/p\u003e\n\n\u003cp\u003eThat division of labor is particularly useful at longer focal lengths. PEC deals with the predictable mechanical pattern of the worm while guiding corrects what is actually happening in the sky and optical system at that moment.\u003c\/p\u003e\n\n\u003ch3\u003eMade to Stay Wired\u003c\/h3\u003e\n\n\u003cp\u003eOne of the CEM120's strongest features has nothing to do with payload capacity.\u003c\/p\u003e\n\n\u003cp\u003eLarge observatory systems accumulate cables quickly: main camera, guide camera, filter wheel, focuser, rotator, dew control, flat panel, and sometimes a second complete imaging train. If those cables hang from the telescope to a computer or power distribution box outside the mount, they eventually have to cross a moving axis.\u003c\/p\u003e\n\n\u003cp\u003eThe CEM120 was designed around permanent cable management.\u003c\/p\u003e\n\n\u003cp\u003eAt the mount you have dedicated power, USB, guide, and auxiliary paths that pass through the structure and emerge near the telescope. The system includes two USB 2.0 connections, three USB 3.0 connections, two 12V outputs rated to 1A, and two higher-current DC outputs rated to 5A, along with ST-4, auxiliary, and iPolar connections.\u003c\/p\u003e\n\n\u003cp\u003eThat lets cameras and accessories connect near the saddle while their computer and power connections remain below the moving axes. In a permanent observatory, fewer external loops mean fewer cables waiting to snag during a slew or meridian flip.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for Remote Operation\u003c\/h3\u003e\n\n\u003cp\u003eThe CEM120 includes Ethernet, Wi-Fi, USB, and RS-232 connectivity directly in the mount.\u003c\/p\u003e\n\n\u003cp\u003eFor a backyard observatory, Ethernet is often the most important of those.

At those focal lengths, a small tracking error that would disappear inside a wide-field pixel scale becomes a visibly elongated star.\u003c\/p\u003e\n\n\u003cp\u003eThat is where low periodic error, careful polar alignment, PPEC, and consistent guiding begin to matter more than flashy GoTo numbers.\u003c\/p\u003e\n\n\u003cp\u003eA C14 can work small galaxies and planetary nebulae at an image scale that reveals structure a short refractor simply cannot resolve. A large RC can spend a season working through galaxy groups and small emission regions. A 6-inch refractor can carry a large-format camera and still leave the mount with generous mechanical margin.\u003c\/p\u003e\n\n\u003cp\u003eThe CEM120 is also large enough for side-by-side systems. One telescope might cover a broad nebula while another works a smaller region at longer focal length, or a dedicated solar or photometric instrument can share the pier with a primary imaging telescope.\u003c\/p\u003e\n\n\u003cp\u003eThat is really what observatory capacity buys: not simply the ability to put one very heavy telescope on the mount, but the freedom to build the imaging system around the science or targets rather than around what the mount can barely carry.\u003c\/p\u003e\n\n\u003ch3\u003eCEM120, CEM120EC, or CEM120EC2?\u003c\/h3\u003e\n\n\u003cp\u003eAll three CEM120 models share the same basic mechanical platform and 115 lb payload rating.

Payload Mount Head With Precision Encoders And Wifi","description":"\u003cp\u003eOnce an imaging system gets large enough, mount capacity is only part of the problem. A C14, large Ritchey-Chrétien, CDK, or substantial refractor may also carry a camera, filter wheel, rotator, focuser, off-axis guider, dew equipment, and perhaps a second telescope. At that point, the mount has to do more than hold the weight. It has to track predictably at a fine image scale, manage a growing collection of cables, and become something you can operate night after night without rebuilding the system around it.\u003c\/p\u003e\n\n\u003cp\u003eThe iOptron CEM120EC is built for that kind of observatory. It carries up to 115 lb (52 kg) of payload, excluding counterweights, on a 57 lb (26 kg) center-balanced mount head. Mechanically, it shares the large worm wheels, bearings, axles, cable-management system, networking, and observatory features of the standard CEM120.\u003c\/p\u003e\n\n\u003cp\u003eThe important difference is on the right-ascension axis. The CEM120EC adds a high-resolution encoder with a published resolution of 0.035 arcsecond. Working with iOptron's Real-Time Periodic Error Correction, that encoder continuously measures RA motion and corrects the periodic component of the worm drive internally. iOptron specifies encoder-corrected periodic error of less than 0.15 arcsecond RMS over the mount's 240-second worm period.\u003c\/p\u003e\n\n\u003cp\u003eThat does not make every other tracking error disappear, and it does not make guiding automatically obsolete. Polar-alignment error, atmospheric refraction, flexure, seeing, and movement elsewhere in the imaging system still exist. What the encoder does is remove most of the repetitive RA gear error before an external guider has to deal with it. At the long focal lengths this mount is designed to carry, that is a meaningful advantage.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-resolution RA encoder.\u003c\/strong\u003e Encoder resolution is 0.035 arcsecond, providing direct measurement of right-ascension motion.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eReal-Time Periodic Error Correction.\u003c\/strong\u003e The encoder continuously corrects the periodic component of RA tracking rather than relying on a previously recorded PEC curve.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eLess than 0.15 arcsecond RMS periodic error.\u003c\/strong\u003e iOptron specifies encoder-corrected PE below 0.15 arcsecond RMS, measured on the bench over one complete 240-second worm cycle.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e115 lb payload capacity.\u003c\/strong\u003e Carries up to 52 kg (115 lb) of telescope and imaging equipment, excluding counterweights.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e57 lb mount head.\u003c\/strong\u003e Approximately a 2:1 payload-to-mount-weight ratio.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eCenter-balanced equatorial design.\u003c\/strong\u003e The CEM architecture keeps the combined system mass centered more directly over the pier or tripod.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e216mm worm wheels on both axes.\u003c\/strong\u003e RA and DEC each use a 360-tooth worm wheel driven by a 26mm worm.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eLarge steel axles and bearings.\u003c\/strong\u003e Both axes use 80mm steel shafts and 125mm bearings.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003ePrecision stepper motors.\u003c\/strong\u003e 128 micro-steps provide a motor resolution of 0.07 arcsecond.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e17.2-inch Losmandy-D saddle.\u003c\/strong\u003e Provides substantial clamping length for large OTAs, long dovetails, and side-by-side systems.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Ethernet and Wi-Fi.\u003c\/strong\u003e Designed for observatory networking and remote control.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eUSB and RS-232 control.\u003c\/strong\u003e Direct wired control is also available for conventional computer connections.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAdvanced through-mount cable management.\u003c\/strong\u003e Multiple USB, power, guide, and auxiliary connections pass through the mount to the telescope side.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003e32-channel GPS.\u003c\/strong\u003e Supplies UTC time and location information to the mount.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eAutomatic zero-position search.\u003c\/strong\u003e The mount can electronically find its reference position for repeatable startup.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eProgrammable parking.\u003c\/strong\u003e Horizontal, vertical, current-position, and user-defined Alt\/Az parking options are available.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eConfigurable meridian treatment.\u003c\/strong\u003e The mount can stop or automatically flip, with settings allowing up to 14° of travel past the meridian.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eST-4 guide port.\u003c\/strong\u003e Traditional autoguiding is supported along with software-based pulse guiding.\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cstrong\u003eOptional internal iPolar.\u003c\/strong\u003e iOptron's CEM120-specific electronic polar scope can be installed for dedicated camera-based polar alignment.\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\u003eWhat the RA Encoder Changes\u003c\/h3\u003e\n\n\u003cp\u003eA conventional worm-driven equatorial mount has periodic error because the worm and worm wheel are physical mechanical parts. Tiny imperfections repeat as the worm rotates, producing a predictable change in RA tracking rate.\u003c\/p\u003e\n\n\u003cp\u003eThe standard CEM120 addresses that with low native periodic error and Permanent Periodic Error Correction. You can measure the recurring error, record a correction curve, and have the mount replay that correction on later nights.\u003c\/p\u003e\n\n\u003cp\u003eThe CEM120EC approaches the same problem differently.\u003c\/p\u003e\n\n\u003cp\u003eIts high-resolution encoder measures the RA axis directly while the mount is tracking. Instead of assuming the worm will repeat a previously measured pattern, Real-Time PEC compares the actual RA motion against where the axis should be and corrects the periodic component as it occurs.\u003c\/p\u003e\n\n\u003cp\u003eThat is why there is no conventional PEC-training routine to perform on the EC version. The encoder is already doing the measurement and correction continuously.\u003c\/p\u003e\n\n\u003cp\u003eiOptron specifies the resulting periodic error at less than 0.15 arcsecond RMS. That number describes the encoder-corrected periodic component measured under controlled bench conditions. It should not be interpreted as a promise that every image taken under the sky will have 0.15-arcsecond total tracking error.\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Encoder Does Not Correct\u003c\/h3\u003e\n\n\u003cp\u003eThe CEM120EC has one high-resolution encoder, and it is on the RA axis.\u003c\/p\u003e\n\n\u003cp\u003eIt can correct the periodic error produced by the RA drive, but it cannot fix an incorrectly aligned polar axis. It does not remove atmospheric refraction. It cannot compensate for differential flexure between a guide scope and the imaging telescope, movement in the optical train, wind, or poor seeing.\u003c\/p\u003e\n\n\u003cp\u003eThat distinction becomes particularly important when discussing unguided imaging.\u003c\/p\u003e\n\n\u003cp\u003eAt forgiving image scales, a carefully polar-aligned CEM120EC may be capable of useful unguided exposures because one of the largest repeating RA errors has already been reduced dramatically. As focal length and exposure time increase, however, slower errors that have nothing to do with the RA worm become increasingly important.\u003c\/p\u003e\n\n\u003cp\u003eVery long unguided imaging at fine image scales generally requires more than an encoder. A sophisticated pointing and tracking model may be needed to account for polar misalignment, atmospheric refraction, mechanical flexure, and other position-dependent effects across the sky.\u003c\/p\u003e\n\n\u003cp\u003eFor most long-focal-length imagers, the practical advantage of the CEM120EC is therefore not that guiding disappears. It is that the guider begins with far less repetitive RA error to correct.\u003c\/p\u003e\n\n\u003ch3\u003eGuiding an Encoder Mount\u003c\/h3\u003e\n\n\u003cp\u003eThere is nothing wrong with guiding the CEM120EC. In fact, with the kinds of telescopes this mount normally carries, guiding remains the most straightforward way to account for errors the RA encoder cannot see.\u003c\/p\u003e\n\n\u003cp\u003eThe difference is how the work is divided.\u003c\/p\u003e\n\n\u003cp\u003eThe encoder handles the fast, repeating periodic component of the RA drive internally. The guider can then respond to the slower residual effects that show up in the actual star position: polar-alignment drift, refraction, flexure, and other changes in the complete imaging system.\u003c\/p\u003e\n\n\u003cp\u003eThat can make an off-axis guider particularly attractive. At long focal lengths, an OAG measures motion through the same optical system as the imaging camera and removes differential guide-scope flexure from the equation.\u003c\/p\u003e\n\n\u003cp\u003eGuide cadence and aggressiveness should still be tuned to the individual telescope, camera, seeing conditions, and guiding software rather than set to one universal number simply because the mount has an encoder.\u003c\/p\u003e\n\n\u003ch3\u003eThe Same CEM120 Mechanical Platform\u003c\/h3\u003e\n\n\u003cp\u003eThe encoder is the defining difference between the CEM120 and CEM120EC, but underneath it is the same substantial mechanical platform.\u003c\/p\u003e\n\n\u003cp\u003eBoth axes use 216mm diameter worm wheels with 360 teeth, driven by 26mm worms. The RA worm period is 240 seconds. The RA and DEC axes use 80mm steel shafts supported by 125mm bearings, and both axes use precision stepper motors with 128 micro-steps.\u003c\/p\u003e\n\n\u003cp\u003eThat scale matters when the payload stops looking like a portable telescope and starts looking like an observatory instrument.\u003c\/p\u003e\n\n\u003cp\u003eA C14 with a full imaging train, large RC or CDK, substantial refractor, or side-by-side arrangement can impose significant bending moments even before the published weight limit is reached. Large shafts, bearings, and saddle surfaces give the optical system a mechanical foundation appropriate to the image scales those telescopes are capable of producing.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Center-Balanced?\u003c\/h3\u003e\n\n\u003cp\u003eTraditional German equatorial mounts position the RA axis to one side of the pier, with the telescope on one side of that axis and the counterweights on the other.\u003c\/p\u003e\n\n\u003cp\u003eiOptron's CEM layout reorganizes that geometry so more of the combined mass of the mount, payload, and counterweights sits directly over the center of the support.\u003c\/p\u003e\n\n\u003cp\u003eThe CEM120EC still uses counterweights and still needs to be balanced. The center-balanced design is not an alternative to that. Its purpose is to keep the overall mass concentrated more naturally over the pier rather than cantilevering the mount structure farther to one side.\u003c\/p\u003e\n\n\u003cp\u003eThat becomes increasingly useful as telescope size and total installed weight increase.\u003c\/p\u003e\n\n\u003ch3\u003e115 Pounds Means Room to Build the System Properly\u003c\/h3\u003e\n\n\u003cp\u003eThe CEM120EC is rated for 115 lb (52 kg) of payload, excluding counterweights.\u003c\/p\u003e\n\n\u003cp\u003eThat does not mean every 115 lb optical system is equally appropriate. A compact telescope and a very long telescope at the same weight create different loads, and iOptron specifically notes that payload capacity depends on OTA size and length.\u003c\/p\u003e\n\n\u003cp\u003eThe real advantage of having this much capacity is often the margin it leaves after the optical tube is mounted.\u003c\/p\u003e\n\n\u003cp\u003eA C14 OTA, for example, still leaves room for the focuser, reducer, filter wheel, rotator, camera, off-axis guider, dew-control equipment, dovetails, and other hardware that turn an optical tube into an imaging system.\u003c\/p\u003e\n\n\u003cp\u003eThe same is true for a large RC or CDK. Instead of choosing accessories based on the few remaining pounds available on the mount, you can design the imaging train around the job it needs to do.\u003c\/p\u003e\n\n\u003cp\u003eCapacity can also be used for side-by-side systems, where two optical tubes share the same mount and clear night.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for the Observatory\u003c\/h3\u003e\n\n\u003cp\u003eOnce a mount becomes permanent, seemingly minor convenience features become some of the most important parts of the system.\u003c\/p\u003e\n\n\u003cp\u003eThe CEM120EC includes Ethernet, Wi-Fi, USB, and RS-232 connections directly on the mount. A hard-wired LAN connection is particularly useful in a permanent installation because the mount can become a stable device on the observatory network rather than relying solely on a local USB connection.\u003c\/p\u003e\n\n\u003cp\u003eAutomatic zero-position search gives the control system a repeatable mechanical reference at startup.

Running those cables externally creates loops that can change tension as the mount moves and can eventually snag during a long slew or meridian flip.\u003c\/p\u003e\n\n\u003cp\u003eThe CEM120EC provides a pre-wired cable-management system through the mount.\u003c\/p\u003e\n\n\u003cp\u003eAvailable connections include two USB 2.0 ports, three USB 3.0 ports, two 12V outputs rated to 1A, two high-current DC outputs rated to 5A, an ST-4 guide connection, AUX, 6P6C, and a dedicated USB path for the optional iPolar.\u003c\/p\u003e\n\n\u003cp\u003eThe result is that much of the imaging equipment can connect near the saddle instead of sending a bundle of loose cables across the RA and DEC axes.\u003c\/p\u003e\n\n\u003cp\u003eFor a permanent observatory, that may be one of the most valuable features on the entire mount.\u003c\/p\u003e\n\n\u003ch3\u003eUnder the Night Sky\u003c\/h3\u003e\n\n\u003cp\u003eThe CEM120EC belongs with telescopes where fine image scale exposes errors that would be nearly invisible in a small wide-field system.\u003c\/p\u003e\n\n\u003cp\u003ePut a large SCT, RC, or CDK on it and smaller targets become the reason for all that focal length. Spiral structure in M51, dust lanes in edge-on galaxies such as NGC 891, compact galaxy groups, small planetary nebulae, and detailed regions inside larger emission nebulae begin to occupy enough pixels to show structure rather than simply appear as small objects in a wide field.\u003c\/p\u003e\n\n\u003cp\u003eAt those image scales, tracking quality becomes part of image resolution. A few arcseconds of repetitive RA error that might disappear inside a short-focal-length system can become visibly elongated stars through a long telescope.\u003c\/p\u003e\n\n\u003cp\u003eThat is where the EC version earns its place. The high-resolution encoder is not adding payload or changing the optical system. It is removing most of the periodic RA error before that error has a chance to become part of the image.\u003c\/p\u003e\n\n\u003cp\u003eThe 115 lb capacity also leaves room for a second telescope. A wide-field refractor can image a complete nebula while a longer-focal-length instrument works a smaller structure within it, or two different cameras can make use of the same clear hours from the same pier.\u003c\/p\u003e\n\n\u003ch3\u003eCEM120, CEM120EC, or CEM120EC2?\u003c\/h3\u003e\n\n\u003cp\u003eAll three models share the same basic 115 lb CEM120 mechanical platform.

The CGX isn't just a prettier face, the mechanics and ergonomics are upgraded as well. Celestron has taken their equatorial mounts to a higher level than ever before.\u003c\/p\u003e\n\u003cp\u003eThe new Celestron CGX go-to equatorial mount looks like a cross between Celestron's CGEM II and the CGE Pro mount, combining the best features from both. The ergonomically-designed CGX has a fresh, attractive, bold appearance and easier set-up than earlier EQ mounts. Mechanical and electronic changes increase the peyload capacity to a solid 55 pounds. The new design provides a lower profile EQ head with a better balance point. Celestron has also added a integrated handles to assist with setup and transportation.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/fmnNr_H9ZQI\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"autoplay; encrypted-media\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eThe CGX mount head contains dual-axis slewing\/tracking motors on each axis for go-to computer control. This is where the real upgrades start.The mount uses spring-loaded worm gears with belt drives. The belt drives offer smooth, quiet operation, with precision slewing and tracking. The motor armatures are skewed to minimize cogging for precise jitter-free low speed tracking. The motor drives and their wiring are all internal, keeping them snag-free and free from dust and debris.\u003c\/p\u003e\n\u003cp\u003eRedesigned electronics deliver constant regulated power to the motors, making them capable of driving the telescope even when the mount is not perfectly balanced. This allows the CGX to have the payload capacity of much larger mounts without sacrificing smooth tracking motion and pointing accuracy across the entire sky. For cutting edge mount control, the CGX supports Celestron's optional SkyPortal WiFi that lets you control the CGX from your smart devices. For automatic sky alignment, you can add Celestron's optional StarSense AutoAlign.\u003c\/p\u003e\n\u003cp\u003eThe mount requires a minimum 3.5 amp 12 VDC power supply to operate. The maximum 3.5 amp power draw happens only briefly when accelerating to the high speed slewing mode from a standing start, or decelerating from the high speed mode when approaching a computer-chosen object. Normal power draw with a well-balanced payload is generally less than half the maximum draw.\u003c\/p\u003e\n\u003cp\u003eThe mount comes with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12V battery pack. The 17 amp hour capacity Celestron Power Tank #4517V is recommended and will operate the mount all night long without danger of running out of power. An optional Celestron #2338PRO 5 amp AC adapter will let you power the CGX all night long from household AC.\u003c\/p\u003e\n\u003cp\u003eTo make a casual polar alignment for visual use quick and easy, there's a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. No polar alignment finderscope is available to aid in the precise polar alignment required for long exposure astrophotography, nor is any needed.\u003c\/p\u003e\n\u003cp\u003eA unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise computerized polar alignment in mere minutes, using any bright star, even when Polaris is hidden by trees or buildings. It works in both northern and southern hemispheres. This technology basically gets rid of the need for a polar alignment scope.\u003c\/p\u003e\n\u003cp\u003eThe supplied 17 pound counterweight is locked in place with a single hand-tighten knob, making it easy to rebalance a scope if you add heavy photographic accessories. If needed, optional counterweights are available to balance very heavy loads.\u003c\/p\u003e\n\u003cp\u003eFor observing or imaging objects near the meridian (the imaginary line passing directly overhead from North to South), the CGX is designed to track 20° past the meridian for uninterrupted imaging through the most ideal part of the sky.\u003c\/p\u003e\n\u003cp\u003eThere are nine motor drive speeds: 0.5x and 1x sidereal for guiding; 4x, 8x, 16x, and 64x for centering; and 1°, 2°, and a fast 5° per second for slewing. Preset tracking rates include sidereal, solar, and lunar. Equatorial tracking modes are available for both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eNew for the CGX mount is a telescope control software that has been developed in conjunction with Planewave Instruments. Planewave Instruments produces some of the most sophisticated imaging systems on the planet. The features of the included software are extremely robust. They include multi-point go-to modeling, focusing, and plate solving. ou will no longer need a third party advanced PC control software as this has it all.\u003c\/p\u003e\n\u003cp\u003eThe supplied NexStar computer hand control has a built-in database of more than 40,000 stars and objects. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; selected variable stars; non-planetary solar system objects; and asterisms.\u003c\/p\u003e\n\u003cp\u003eYou can also store and edit the right ascension and declination of 100 additional user-defined objects of your own choosing, such as the comet and asteroid coordinates published monthly in Astronomy and Sky \u0026amp; Telescope magazines. The computer control can find any of those objects with only a few keystrokes, and track them with high accuracy for visual or photographic applications. There is enhanced information on over 200 of the most note-worthy objects.\u003c\/p\u003e\n\u003cp\u003eThe NexStar hand control provides a constant digital r. a. and dec readout of the scope's position on the sky. This provides much greater accuracy than conventional manual setting circles for star-hopping or locating objects by their celestial coordinates alone, should you want to observe the old-fashioned way without using the computer to find objects for you.\u003c\/p\u003e\n\u003cp\u003eThe software built into the NexStar hand control includes mount calibration, database filter limits, hibernate, five alignment procedures, user-defined slew limits, a new \"All-Star\" polar alignment routine that uses any bright star for a quick and accurate polar alignment, and more. Built-in adjustable backlash compensation permits precise corrections during astrophotography and when observing visually at high powers. A high precision pointing subroutine in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope.\u003c\/p\u003e\n\u003cp\u003eThe software includes permanent programmable periodic error correction (PEC) to correct for the minor periodic tracking errors inherent to all worm drives that might otherwise mar your long exposure photographs. The CGX mount retains the PEC recordings when it is powered down. The hand control and motor control software is flash-upgradeable to allow you to download the latest product updates over the Internet to keep your CGX mount always at the cutting edge of technology.\u003c\/p\u003e\n\u003cp\u003eAn autoguider port is located on the electronic pier for long exposure astrophotography. The autoguider port can use a six-pin RJ-12 modular jack ST-4 compatible CCD autoguider to automatically control the drive motors during long exposure astrophotography.\u003c\/p\u003e\n\u003cp\u003eFive different alignment methods are built into the Celestron mount's NexStar computer: 2-star align, quick align, 1-star align, last alignment, and solar system align. This allows you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. Alignment is easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take your CGX-mounted scope outdoors.\u003c\/p\u003e\n\u003cp\u003eIn addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive SkySync GPS module) for full GPS (Global Positioning System) accuracy. Adding GPS to the computer is something no competitively-priced mount can do. Once the scope is approximately polar aligned, the 16-channel SkySync GPS system uses signals from government satellites to calculate the scope's location on earth with an accuracy measured in meters. The system also calculates the current time based on the split second accuracy of the GPS time signals.\u003c\/p\u003e\n\u003cp\u003eAfter the SkySync quickly completes these calculations, and enters the information into the computer control for you automatically, the computer then orients the scope with the sky, slews to a pair of guide stars, asks you to confirm that the stars are in the center of the field (and center them if they're not precisely aligned), and then starts finding and tracking over 40,000 objects for you at your command. With the Celestron CGX go-to mount and the SkySync, orienting your scope in time and space on earth and aligning it on the sky becomes almost as easy a task as simply turning the mount on.\u003c\/p\u003e\n\u003cp\u003eThe new, 2\" diameter adjustable height tripod has graduated markings on the legs to help with quick leveling.The center leg brace is drilled to form a convenient accessory tray that holds 1.25\" and 2\" eyepieces to keep them up out of the dew-soaked grass.\u003c\/p\u003e\n\u003cp\u003eOptical tubes are installed on the CGX mount using a Dual-Slot on the mount head that accepts either a Celestron CGE-style or Losmandy D-plate dovetail slide bar or the narrower Vixen-Style dovetail. This allows the optical tube to be quickly and precisely balanced fore and aft on the mount, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and takedown times are exceptionally fast, as a single large hand-tighten knob holds the optical tube in place.

Stepper motors are quieter than servo motors, providing accuracy up to 1 arc minute without waking your neighbors from buzzing motors.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eYou might get an itch to do some astro-photography with this mount as well.  Have no fear, it was designed with you in mind.  The EQ6-R boasts a number of features to aid astrophotographers. The built in ST-4 Autoguider port turns this mount into an astrophotography powerhouse, allowing you to utilize most of today's best autoguiders. Using the integrated RS232 port, you can control the telescope from your computer and take advantage of today's most advanced astronomy software. With a weight capacity of 44 lbs, the EQ6-R can handily support an optical tube, imaging accessories and camera.  Sky-Watcher includes an illuminated polar finderscope to aid the polar alignment process. The finderscope features a circular grid reticle for the northern hemisphere, consistent with todays popular polar alignment apps. For astronomers in the southern hemisphere, the constellation Octans is built into the reticle as well. Even without a clear view of Polaris, the EQ Pro can be polar aligned using our SynScan hand controller. Simply choose one of the visible stars listed and use the latitude adjustment screws to center it in the eyepiece.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eUsing the proprietary SynScan hand controller, the EQ6-R Pro provides a user-friendly interface with automatic slewing to over 42,000 objects in the night sky.

It is more stable because the center of gravity is directly over the center of its base. It is more portable because it can be broken down into smaller component parts than a fork-mount telescope for easier storage and transportation. As for being universally adaptable, it can be used with physically long refractors and reflectors as well as short-tube catadioptric scopes.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/3Nzf-Ava6OM\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"autoplay; encrypted-media\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eFor astrophotography, the German equatorial mount offers easier balancing; unlimited space at the rear of the telescope tube to mount a long camera equipment train that can't bump into the drive base, as is the case with many fork-mounted scopes; and whole sky access that many fork-mounted scopes can't achieve.\u003c\/p\u003e\n\u003cp\u003eFor German equatorial mount lovers and serious astrophotographers, Celestron has developed this new 75 pound payload capacity CGX-L equatorial mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeavy duty mount head:\u003c\/strong\u003e The Celestron CGX-L is a newly-designed high payload capacity\/high precision go-to German equatorial mount that epitomizes all of these German equatorial mount virtues. With its full 75 pound payload capacity it will carry Celestron SCT\/HD optical tubes up to 14\" in aperture, as well as virtually any other optical tube and accessory payload weighing up to 75 pounds.\u003c\/p\u003e\n\u003cp\u003eNew features are everywhere in the Celestron CGX-L mount head. It has ergonomic handles that help you move the 47 pound head with ease. That's right; the head weighs only 47 pounds, but will carry 75, an incredible load to weight ratio.\u003c\/p\u003e\n\u003cp\u003eIn addition to the standard auxiliary ports in the mount head, additional accessory ports are built into the dovetail saddle plate of the equatorial head. There are two auxiliary ports as well as an autoguider port. The internal cabling of the CGX-L mount works hand in hand with these new ports on the saddle helping the imager in all of us manage our cables.\u003c\/p\u003e\n\u003cp\u003eThe dovetail saddle plate is longer for added stability and accepts both Vixen\/AVX and Losmandy\/Celestron D Style dovetails.\u003c\/p\u003e\n\u003cp\u003eThere are built-in home and limit sensors. The home sensor takes the scope back to its home position at any time and the limit sensor prevents the mount from slewing past a certain point. Built-in mechanical hard stops protect your scope from damage should you forget to lock the mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMount drive system:\u003c\/strong\u003e The CGX-L mount head contains 144mm worm wheels in both right ascension and declination. The improved drive system uses a belt-driven spring-loaded worm gear. This allows the drive to maintain optimum gear mesh for smoother tracking and less backlash.\u003c\/p\u003e\n\u003cp\u003eThe mount requires 2.5 Amp 12 VDC power to operate. The maximum 2.5 amp power draw happens only briefly when accelerating to the high speed slewing mode from a standing start. Normal power draw with a well-balanced payload is generally considerably less than half the maximum draw. The mount comes with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12 VDC battery pack. The 17 amp hour capacity Celestron Power Tank\u003cbr\u003e#4517V is recommended and will operate the mount all night long without danger of running out of power. The Celestron #2338PRO ac adapter will let you operate the mount from household AC power for backyard and observatory use.\u003c\/p\u003e\n\u003cp\u003eSpecially designed power management electronics deliver constant regulated power to the motor so that it is capable of driving the mount even when your scope not perfectly balanced. This allows your CGX-L to have the payload capacity of that of much larger (and more expensive) mounts without sacrificing smooth tracking motion and pointing accuracy across the entire sky.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolar alignment:\u003c\/strong\u003e To make a casual no-tool polar alignment for visual use quick and easy, there's a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. If serious long exposure astrophotography is in your plans, the special All-Star Polar Alignment software described below allows you to choose any bright alignment star for a software-assisted alignment of the mount's polar axis, even if you can't see the North Star. The mount also has upgraded adjustments for latitude and azimuth. Large one hand knobs make moving a fully-loaded mount head easy with a simple twist of the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCounterweight:\u003c\/strong\u003e The CGX-L mount comes with one 22 pound counterweight.The counterweight locks in place on the 5 pound steel counterweight shaft with a single hand-tighten knob, making it easy to rebalance your scope in right ascension if you add heavy photographic accessories. If needed, optional counterweights are available to balance very heavy loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMounting an optical tube:\u003c\/strong\u003e Optical tubes are installed on the CGX-L mount using a slot on the mount head that accepts a Celestron CGE-style\/Losmandy D-plate dovetail or a Celestron AVX\/CG5\/Vixen slide bar. This allows the optical tube to be quickly and precisely balanced fore and aft on the mount in declination, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and take downtimes are exceptionally fast, with large hand-tighten knobs holding the optical tube in place.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMount weight:\u003c\/strong\u003e The equatorial head and thread-in counterweight shaft total 52.6 pounds. The supplied counterweight weighs 22 pounds. The new ergonomic handles on the mount head make it much easier for a single person to move and break down the mount in the field with ease.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNexStar computer hand control:\u003c\/strong\u003e The NexStar computer hand control of the CGX-L mount has a built-in database of more than 40,000 stars, deep space objects, and solar system objects it can locate for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable stars; non-planetary solar system objects; and asterisms. It contains enough fascinating objects to keep you busy observing for the rest of your life.\u003c\/p\u003e\n\u003cp\u003eYou can also store and edit the right ascension and declination of 100 objects of your own choosing, such as the comet and asteroid coordinates published monthly in Astronomy and Sky \u0026amp; Telescope magazines.The computer control can quickly find any of those objects at your command, and track them with high accuracy for visual observing or astrophotography.\u003c\/p\u003e\n\u003cp\u003eAll of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. This display leads you through the steps necessary to line up the scope on the sky, locate objects, control scope functions like the brightness of the hand control display, and much more. It shows you basic information about the object being viewed (such as the object's name, catalog designation, type, magnitude, and so forth). In addition to this basic information, there is enhanced information on over 200 of the most note-worthy objects. The display can also show you the right ascension and declination coordinates at which the scope is aimed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAlignment on the sky and go-to accuracy:\u003c\/strong\u003e No polar alignment finderscope is available for the CGX-L mount, nor is any needed. A unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise polar alignment in mere minutes for long exposure astrophotography, even if the celestial pole is hidden by trees. It works in both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eAlthough the telescope's tracking may be very good after alignment, pointing accuracy may need to be improved (particularly if you are trying to located small objects on a CCD chip), depending on how close your initial mechanical alignment was on the pole, and by much the mount had to be moved during polar alignment. If that's the case, you can easily update your telescope's star alignment in a minute or two if necessary.\u003c\/p\u003e\n\u003cp\u003eOnce polar aligned, several different sky alignment methods are built into the NexStar computer to line up the scope on the celestial sphere, allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. These include 2-Star Align, Solar System Align, Last Alignment, Quick Align, and 1-Star Align,\u003c\/p\u003e\n\u003cp\u003eWith just a standard hand control alignment, the CGX-L computer has the ability to center a star in your telescope's eyepiece or on a CCD chip to within 5 arc minutes. Using the NexStar computer's advanced pointing features (such as Calibration Stars, Sync, and Precise Go-To) further improves the pointing accuracy to as low as 1 arc minute in the desired region of the sky. The high precision pointing subroutine (Precise Go-To) in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope.

compact, travel-ready package. Whether you're a visual observer looking to support a large refractor or a dedicated astrophotographer aiming for sub-arcsecond tracking, the CEM40 gives you the tools to do the job with a minimum of fuss and a maximum of confidence.\u003c\/p\u003e\n\u003cp data-start=\"1008\" data-end=\"1699\"\u003eWeighing just \u003cstrong data-start=\"1022\" data-end=\"1037\"\u003e15.8 pounds\u003c\/strong\u003e, the CNC-machined CEM40 head supports a \u003cstrong data-start=\"1078\" data-end=\"1098\"\u003e40-pound payload\u003c\/strong\u003e, not including counterweights. That’s a 2.5:1 payload-to-weight ratio—one of the best in its class—meaning you can mount everything from an 8\" RC to a fully loaded imaging train without pushing the mechanics to their limit. The secret to its stability lies in iOptron's patented \u003cstrong data-start=\"1378\" data-end=\"1420\"\u003eCenter-Balanced Equatorial Mount (CEM)\u003c\/strong\u003e design. By placing the center of gravity directly over the tripod or pier, the mount minimizes torque, balances more naturally, and reduces stress on the motors and gears. The result is smoother tracking, faster balancing, and a setup that simply feels more stable in the field.\u003c\/p\u003e\n\u003chr data-start=\"1701\" data-end=\"1704\"\u003e\n\u003ch3 data-start=\"1706\" data-end=\"1787\"\u003eBuilt-In iPolar™ for Fast, Accurate Alignment—Even When You Can’t See Polaris\u003c\/h3\u003e\n\u003cp data-start=\"1789\" data-end=\"2426\"\u003eOne of the standout features of the CEM40 is its \u003cstrong data-start=\"1838\" data-end=\"1894\"\u003eintegrated iPolar™ electronic polar alignment system\u003c\/strong\u003e. Permanently mounted in the RA axis and aligned at the factory, iPolar uses plate solving and a built-in camera to calculate your true celestial pole alignment in real time—even when Polaris is blocked by trees, buildings, or heavy light pollution. You no longer need to strain your neck, guess at reticle patterns, or waste time on iterative alignment routines. Just launch the software, follow a simple on-screen guide, and you’ll be polar aligned in minutes with a level of precision that visual polar scopes simply can’t match.\u003c\/p\u003e\n\u003chr data-start=\"2428\" data-end=\"2431\"\u003e\n\u003ch3 data-start=\"2433\" data-end=\"2539\"\u003eEngineered for Performance: Stepper Motors, Zero Backlash Worm Gears, and iOptron’s Proven Electronics\u003c\/h3\u003e\n\u003cp data-start=\"2541\" data-end=\"3085\"\u003eInside the CEM40’s anodized red-and-black housing, iOptron has installed \u003cstrong data-start=\"2614\" data-end=\"2642\"\u003eprecision stepper motors\u003c\/strong\u003e paired with \u003cstrong data-start=\"2655\" data-end=\"2693\"\u003ezero-backlash 216-tooth worm gears\u003c\/strong\u003e on both axes.

Those effects happen outside the worm gears the encoders are monitoring.\u003c\/p\u003e\n\n\u003cp\u003eThat is why guiding can still make sense with the CEM120EC2, particularly at the long focal lengths and fine image scales this mount is capable of supporting.\u003c\/p\u003e\n\n\u003cp\u003eThe difference is that an external guider is not starting with an ordinary uncorrected gear train.

Objects such as NGC 891, Stephan's Quintet, the Cat's Eye Nebula, M51, and the smaller galaxies scattered through spring skies become more than tiny features in a wide field.\u003c\/p\u003e\n\n\u003cp\u003eAt those focal lengths, tracking becomes part of image resolution. A periodic error that would be nearly invisible through a short refractor can spread a star across multiple pixels through a long-focal-length telescope.\u003c\/p\u003e\n\n\u003cp\u003eThe EC2 cannot improve the seeing or make the optical system sharper than physics allows. What it can do is reduce the mount itself as a source of uncertainty, with direct positional feedback on both axes and encoder-corrected periodic error on RA.\u003c\/p\u003e\n\n\u003cp\u003eThere is also enough capacity for dual systems. A wide-field refractor can record an entire nebula while a longer-focal-length instrument works a small structure within it, allowing the same clear hours to serve two very different image scales.\u003c\/p\u003e\n\n\u003ch3\u003eFrom the Cloudy Nights Community\u003c\/h3\u003e\n\n\u003cp\u003eExperienced CEM120EC2 owners tend to make an interesting point about guiding: once the mount is behaving properly, too much guider intervention can become counterproductive.\u003c\/p\u003e\n\n\u003cp\u003eOwners working with large SCTs and other long-focal-length systems have reported excellent guiding after tuning their software to make relatively gentle corrections.

An optional counterweight will be needed to balance heavier loads up to its rated 70 pound capacity. Most astrophotographers will probably want to limit the instrument payload to a maximum of about 40 pounds, to benefit from the increased stability of having a smaller instrument on an over-sized mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDrive system details:\u003c\/strong\u003e The CEM70 has 248-tooth 151mm diameter aluminum drive gears in both right ascension and declination. Brass worms are standard. Periodic error is ~+\/-3.5 arc seconds peak to peak. Permanent perriodic error correction is standard. The drive uses a patent-pending non-contact magnetically loaded gear system. Gear switches in both RA and dec disengage the gears for easier load balancing,\u003c\/p\u003e\n\u003cp\u003eThe standard equipment dual-axis DC stepper motors with encoders use a temperature-compensated quartz crystal oscillator controller to provide 0.06 arc second per step resolution, assuring an imperceptible stepping motion during visual observing and imaging. User-adjustable backlash compensation is standard.\u003c\/p\u003e\n\u003cp\u003eThe DC motors require a 12VDC (9~15VDC) power supply capable of providing a 2A output. The motors draw 0.6A while tracking and 1.1A while slewing. There are nine guiding, centering, and slewing speeds available: sidereal and 2x sidereal for guiding; 8x, 16x, 64x, and 128x sidereal for centering; and 256x (1°\/sec), 512x (2°\/sec) sidereal, and a maximum speed of ~3.75°\/sec for slewing. There are five user-selectable drive speeds: sidereal, solar, lunar, the King rate for imaging near the horizon, and a user-defined speed.\u003c\/p\u003e\n\u003cp\u003eThe iOptron CEM70 comes with an appropriately-sized universal 100V ~ 240VAC to 12VDC adapter.

The instrument panel has two 12VDC outlets for powering your CCD camera or electric focuser. There are four non-powered USB 2.0 ports with Type A connectors for connecting to accessories. A 6P6C port is included to bridge the guiding port or accessories with a 6P6C\/6P4C plug. The input panel next to the polar scope includes a 12VDC power input (5A maximum), a USB 2.0 port with a Type B connector, and a 6P6C port. These USB input and output ports allow you to wire up connections inside the mount head to suit your individual requirements. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMount details:\u003c\/strong\u003e The CEM70's innovative center-balanced design mount puts the weight of the payload at the center of gravity, allowing greater natural stability and lighter weight - a nice benefit when setting up at a remote site. The equatorial head, not counting the standard equipment counterweight or tripod, weighs only 30 pounds (13.6 kg) for the highest payload to mount weight ratio in its category.\u003cbr\u003e\u003cbr\u003eThe mount is designed to operate in both northern and southern hemispheres at latitudes from 0° to 70°. Twin adjustment knobs in the base of the mount let you fine-tune the azimuth alignment on the pole over a +\/-8° arc. When using the CEM70 mount at latitudes below 10°, a few simple adjustments of the unique variable position counterweight shaft lets you change the counterweight bar angle so the counterweight does not bump the tripod during use.\u003c\/p\u003e\n\u003cp\u003eThe standard equipment iPolar finder for quick and accurate polar alignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptical tube mounting method:\u003c\/strong\u003e The spring-loaded mount head has an 8\" dual saddle that accepts both industry-standard Losmandy \"D-Plate\" and Vixen-style dovetails.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNo tripod or pier supplied:\u003c\/strong\u003e Because of the CEM70's ability to be used with a variety of scope types in both observatory and in-the-field situations, no tripod is supplied.

GM-8 Equatorial Head With Gemini II Go-To Computer","description":"\u003cp\u003eThe Losmandy GM-8 head with a Gemini II go-to computer is a well made high-precision go-to mount that is ideal for the serious visual observer\/astrophotographer who needs a highly portable mount with a 30 lb payload capacity.\u003c\/p\u003e\n\u003cp\u003eThe Losmandy GM-8 mount with a Gemini II computer system is a well-made, high-precision German equatorial head that is very portable, but can still hold a respectable payload. It is rated at a 30 pound payload capacity, making it an excellent choice for almost every 4\" refractor, most 6\" Maksutov-Cassegrains and Maksutov-Newtonians, and even some 5\" refractors. It comes standard with a Gemini II computer and dual axis drive system whose built-in drive corrector includes periodic error correction, making it an excellent photographic platform for the serious astrophotographer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Losmandy GM-8 equatorial head:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAll parts are machined from stainless steel or aluminum. All aluminum parts are black anodized. All hardware is stainless steel for rust-free long life.\u003c\/p\u003e\n\u003cp\u003eBearings include one 2.100\" diameter needle thrust bearing, one 2.000\" diameter needle thrust bearing, and two 1.500\" diameter needle bearings. Right ascension and declination shafts are precision-machined of 1.250\" diameter aluminum. The 180 tooth main drive gear is machined of 2.812\" diameter 7075 aluminum. The heat-treated and ground stainless steel worm is in a dual supported ball bearing housing. There is a one-knob design variable slip clutch on each axis. The drive uses a 160 oz\/in stepper motor, with 1.0 arc second steps.\u003c\/p\u003e\n\u003cp\u003eThe unique fully-locking tangent arm design altitude adjustment allows use over a 0-64 degree latitude range. There is a single large adjustment knob for easy alignment. The latitude scale is laser engraved in 2 degree increments. The two-knob azimuth control provides a +\/- 8.5 degree adjustment range and positive locking.\u003cbr\u003e3.500\" diameter laser engraved setting circles are marked in 6 minute increments in right ascension and 2 degree increments in declination. The right ascension circle is engraved for both Northern and Southern Hemisphere use. The r. a. circle is a Porter slip ring design, so that when the mount is moved manually, or driven electronically, the r. a. circle follows the stars with no need to be reset periodically.\u003c\/p\u003e\n\u003cp\u003eA dovetail saddle that can accept both Losmandy D-plate and Vixen-style OTA dovetails allows for the fast interchanging of tube assemblies. Its range of fore and aft adjustment reduces the need for declination weights. The stainless steel counter weight shaft is removable and has a safety knob. The payload capacity is 30 lbs. The equatorial head weighs 21 lbs., exclusive of counterweight(s). The mount comes with one 7 lb. counterweight standard. Additional 11 lb. and 21 lb. counterweights are available to balance heavy payloads.\u003c\/p\u003e\n\u003cp\u003eAn optional illuminated through-the-axis polar alignment scope works in both Northern and Southern Hemispheres.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Losmandy GM-8 Gemini II go-to dual-axis electronics:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Losmandy Gemini 2 system is a DC servo motor-based go-to computerized positioning system. The upgraded Maxon DC servo motors supplied with the Gemini 2 have higher torque through their entire range of tracking and slewing speeds than the motors on standard Losmandy mounts that don’t have a go-to capability. The drive system has a dual 12~18V DC input\/output and draws 3.0A maximum.\u003c\/p\u003e\n\u003cp\u003eThe servo motors used in the Gemini 2 have two main advantages over the stepper motors normally used in scopes. First, servo motors run with a continuous smooth rotation, rather than the discrete short steps taken by stepper motors. This results in less image “jitter” in extremely high magnification planetary observing and stars that are tighter and more point-like in critical astrophotography applications. Second, servo motors have very high torque, even at high slewing speeds. As a result, the Gemini 2 system can deliver a maximum slew rate of approximately 6 degrees per second with the GM-8 mount.\u003c\/p\u003e\n\u003cp\u003eThe Gemini 2 computer is a stand-alone system, with no PC required for operation in the field. A full-color graphic touch screen on the hand control of the Gemini 2 system clearly displays all functions. There is a classic four-button diamond pattern for guiding, centering, moving, and slewing on both the touch screen on the front of the computer and on a tactile four-button membrane on the rear. There is also support for the original Gemini four-button controller.\u003c\/p\u003e\n\u003cp\u003eThe Gemini 2 has 0.5 arc second positioning accuracy during go-to operation. It is GPS-compatible with an optional #LGPSG2 receiver. It has Ethernet 10\/100 with full IP function to permit operation from anywhere using a browser, ASCOM, or an application over the web or serial port. There is also custom mount support using a programmable gear rate function.\u003c\/p\u003e\n\u003cp\u003eThe more than 40,000 object memory of the Gemini 2 is non-volatile and the system contains a real-time clock. You can select from English, French, Spanish, and German language displays. There are two USB ports; one for virtual COM to PC, and one for an ASCOM or planetarium program. There is PEC correction built in and an auto-guider port. The firmware can be upgraded via the internet. There are ports for future high-resolution encoders and a multi-function A\/D I\/O serial port.\u003c\/p\u003e\n\u003cp\u003eThe following databases, comprising about 41,000 stars and objects, are built into the Gemini 2 system, more than enough to keep even the most avid observer busy for some time! You get the Messier catalog (110 objects), the revised NGC catalog (7840 objects), the revised IC catalog (5386 objects), the Sh2 Sharpless 2 catalog (313 objects), a catalog of 167 bright stars, and a 17,635 star catalog of SAO stars.\u003c\/p\u003e\n\u003ch2\u003eTech Details: \u003c\/h2\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e1 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Losmandy","offers":[{"title":"Default Title","offer_id":40481991622729,"sku":"GM8GH","price":2345.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/gm8-1_1.jpg?v=1675380039"},{"product_id":"ioptron-cem26-center-balanced-go-to-german-equatorial-mount-with-hard-case-and-1-75-literoc-tripod","title":"iOptron CEM26 \"Center Balanced\" Go-To German Equatorial Mount With Hard Case Ipolar And 1.75\" Literoc Tripod","description":"\u003ch3 data-start=\"347\" data-end=\"444\"\u003eiOptron CEM26 “Center Balanced” GoTo Mount with iPolar, Hard Case, and 1.75\" LiteRoc Tripod\u003c\/h3\u003e\n\u003cp data-start=\"445\" data-end=\"463\"\u003e\u003cstrong data-start=\"445\" data-end=\"463\"\u003eItem #: C262A3\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"465\" data-end=\"870\"\u003eLightweight, precise, and thoughtfully engineered for the field—the \u003cstrong data-start=\"533\" data-end=\"550\"\u003eiOptron CEM26\u003c\/strong\u003e offers the perfect blend of portability and performance.

CEM26 out under the stars. Whether you’re an astrophotographer looking for precision or a visual observer who appreciates portability, the CEM26 gives you the confidence of high-end features in a compact, travel-ready package. It’s one of the smartest, most efficient mounts in its class—and thanks to its unique center-balanced architecture, it’s also one of the most stable.\u003c\/p\u003e\n\u003cp\u003eThis version of the CEM26 includes iOptron's \u003cstrong\u003eAccuAlign optical polar scope\u003c\/strong\u003e for fast, accurate polar alignment, and it rides on the rugged \u003cstrong\u003e1.75\" LiteRoc stainless steel tripod\u003c\/strong\u003e, combining performance with lightweight portability.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003ePrecision Performance with a Smart \"Z\" Twist\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the CEM26 is iOptron’s patented “Z”-shaped center-balanced design. By placing the payload directly over the tripod’s center of gravity, the CEM26 achieves improved natural stability and a higher effective payload-to-weight ratio. This thoughtful design minimizes flexure and counterweight demand, which means easier setup and smoother tracking—whether you're imaging narrowband nebulae or scanning Messier objects from your driveway.\u003c\/p\u003e\n\u003cp\u003eDespite its strength, the mount head weighs just \u003cstrong\u003e10.4 lbs (4.7 kg)\u003c\/strong\u003e. That’s a welcome relief when you’re hauling gear into a dark-sky site. And thanks to its \u003cstrong\u003eadjustable counterweight bar\u003c\/strong\u003e, you can use the mount at low latitudes without fear of the counterweight hitting the tripod legs. Even better, the polar scope is never blocked by the declination shaft, making it fast and easy to align anytime—even after dark.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eBuilt for Astrophotographers (But Visual Users Will Love It Too)\u003c\/h3\u003e\n\u003cp\u003eWith a \u003cstrong\u003e26 lb (11.8 kg)\u003c\/strong\u003e payload capacity, the CEM26 is ideal for imaging rigs with mid-sized refractors or compact reflectors, especially when paired with a guide scope and camera. Inside, a \u003cstrong\u003espring-loaded gear system\u003c\/strong\u003e with adjustable loading force keeps backlash at bay, while \u003cstrong\u003ebelt-driven stepper motors\u003c\/strong\u003e deliver quiet, precise slewing and tracking with low periodic error—typically less than ±10 arcseconds. Permanent Periodic Error Correction (PEC) is also supported for improved long-exposure guiding.\u003c\/p\u003e\n\u003cp\u003eNeed to balance your scope manually? The gear switches on both the RA and DEC axes let you disengage the worm gears for easy balancing—another thoughtful touch for field use.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eAccurate GoTo Control with Room to Grow\u003c\/h3\u003e\n\u003cp\u003eControlling the mount is iOptron's \u003cstrong\u003eGo2Nova 8409 hand controller\u003c\/strong\u003e, which comes preloaded with one of the largest GoTo databases in the industry—over \u003cstrong\u003e212,000 celestial objects\u003c\/strong\u003e, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eNamed objects\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMessier, NGC, IC, Caldwell catalogs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eUGC, MCG galaxy catalogs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDouble stars, variables, exoplanets, and more\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe four-line LCD screen is easy to read, even with gloves, and the user interface is intuitive for beginners while offering plenty of flexibility for advanced users.

(4.5kg) counterweight, an 8\" x 20mm counterweight shaft, and a 5\" x 20mm counterweight shaft extension. These can be combined to hold the GEM28's maximum payload of 28 pounds (12.7kg). However, most astrophotographers will probably want to limit the instrument payload to a maximum of about 20 pounds, to benefit from the increased stability of having a smaller instrument on an over-sized mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDrive system details:\u003c\/strong\u003e The synchonous belt transmission of the GEM28 has a 144-tooth 88mm diameter drive gear in right ascension and a 144-tooth 88mm diameter drive gear in declination.  Brass worm gears are standard.  Both the right ascension axis and declination shaft are 30mm in diameter.\u003c\/p\u003e\n\u003cp\u003eThe standard equipment dual-axis stepper motors with encoders provide 0.17 arc second per step resolution, assuring an imperceptible stepping motion during visual observing and imaging. Available user-selected tracking rates include sidereal, solar, lunar, King, and a user-defined speed. User-adjustable backlash compensation is standard.\u003cbr\u003e\u003cbr\u003eThere are nine guiding, centering, and slewing speeds available: sidereal and 2x sidereal for guiding; 8x, 16x, 64x, and 128x sidereal for centering; and 256x (1°\/sec), 512x (2°\/sec) sidereal, and a maximum speed of ~4°\/sec for slewing.\u003cbr\u003e\u003cbr\u003eThe iOptron GEM28 comes with an AC adatper.  It also comes with an RS232 cable and port for mount firmware upgrade and ASCOM control using an optional computer.

The equatorial head, not counting the standardequipment 10 pound (4.5kg) counterweight, weighs only 10 pounds (4.5kg) for the highest payload to mount weight ratio in its category (2.80). \u003c\/p\u003e\n\u003cp\u003eThe particular unit comes with a hard carrying case for the head as standard equipment.\u003c\/p\u003e\n\u003cp\u003eThe mount is designed to operate in both northern and southern hemispheres at latitudes from 10° to 70°. A large adjustment control between the vertical side pieces of the mount and an indicator window in one of the side pieces makes it easy to align the mount on the celestial pole in altitude. Twin adjustment knobs in the base of the mount let you fine-tune the azimuth alignment on the pole over a +\/-6° arc.\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe GEM28A mount has an integrated electronic polar finder scope known as the iPolar.
