The advanced EdgeHD optical system uses a dedicated dual-element field flattener lens made from premium Schott optical glass in its central baffle tube to reduce off-axis coma and produce aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography).\u003c\/p\u003e\n\u003cp\u003eIn addition to reduced off-axis coma, the EdgeHD optics deliver an astrograph-quality focal plane more than three times flatter than standard Schmidt-Cassegrains and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see sharp and point-like stars to the very edges of some of the largest CCD and DSLR chips available today.\u003c\/p\u003e\n\u003cp\u003eFor the ultimate in brightness and contrast, the CGEX-L 925HD optical tube has state-of-the-art Starbright XLT multicoatings. Its light grasp is approximately 1125 times that of even the sharpest dark-adapted eye, revealing to your eye and camera star clusters, nebulas, planets, and galaxies in amazing detail. The Fastar-compatible optical tube even allows imaging down to an incredibly-fast f\/2 focal ratio using optional accessories.\u003c\/p\u003e\n\u003cp\u003eThe Celestron CGX-L 925HD's CGX-Lmount can carry payloads of up to 75 pounds, more than three times the weight of the scope's 21 pound 9.25\" optical tube. This makes this mount\/OTA combination rock-steady, no matter how many heavy visual and imaging accessories you add to the system.\u003c\/p\u003e\n\u003cp\u003eThe scope's advanced NexStar computer hand control makes finding over 40,000 of those stars and objects easy and automatic, so you can spend more time looking at those objects, rather than looking for them.\u003c\/p\u003e\n\u003cp\u003eGranted, many people might feel that a 126 pound mount with a 75 pound payload capacity is a case of overkill for a 21 pound optical tube. For those who must travel to a dark sky site to use their scope, that might indeed be the case. That's why Celestron also puts the same 9.25\" EdgeHD optical tube on the lighter CGEMII mount (#CGEMII9HD), to make travel easier. However, for those who have a permanent observatory site and are looking to grow their system in stages, the CGX-L 925HD makes a sensible choice as the heart of a bigger scope array to come. You can add virtually any size or weight optical tube you like later on, without having to upgrade your mount. And while you are waiting for your aperture fever to become affordable, the superb flat-field reduced-coma optics of the 9.25\" CGX-L 925HD are big enough, and good enough, to keep you happily observing and imaging for years to come, and even for years after you get the \"big\" optical tube to put on your CGX-L mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Optical System . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEdgeHD aplanatic Schmidt-Cassegrain optical tube:\u003c\/strong\u003e 9.25\" aperture (2350mm focal length f\/10). Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations (aplanatic design). The 22\" long aluminum optical tube has a large handle on the rear cell and weighs only 21 pounds, making it easy to transport and assemble the scope in the field.

It also increases the contrast on subtle lunar, planetary, and nebula details when compared with a scope with ordinary coatings or multicoatings. For more details, click on the \"Starbright XLT\" icon above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube vents:\u003c\/strong\u003e Two cooling vents on the rear cell allow warm air to be released from behind the primary mirror when the scope is taken out for a night's observing or imaging. This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio. An optional Fastar lens assembly lens replaces the scope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/10 position at the Cassegrain focus at the rear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirror locks:\u003c\/strong\u003e Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (when moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of the optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design, with a wide 5.8 degree field of view, mounted in a spring-loaded easy-adjust quick release bracket..\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStar diagonal:\u003c\/strong\u003e 2\" first-surface mirror type, with 1.25\" adapter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Mount . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe German equatorial mount has long been the favored choice of astronomy buffs and astrophotographers because of its stability and portability. It is more stable because the center of gravity is directly over the center of its base, and more portable because it can be broken down into smaller component parts than a fork-mount telescope for easy storage and transportation.\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\u003eCelestron has looked to update the way that people interact with their equipment. This quest has brought out a new EQ Mount Series, the CGX. This particular model in the series is the CGX-L and boasts a 75 pound payload capacity.\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\u003e\u003cstrong\u003eNew features are everywhere in the mount head:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1. Ergonomic handles help you move the 47 pound head with ease. That's right; the head weighs 47 pounds and will carry 75. It is an incredible load to weight ratio.\u003c\/p\u003e\n\u003cp\u003e2. Additional accessory ports 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\u003e3. The dovetail saddle plate is longer for added stability and will also accept both Vixen\/AVX and Losmandy\/Celestron D Style dovetails.\u003c\/p\u003e\n\u003cp\u003e4. There are built in home and limit sensors. The home sensor will take the scope back to its home position at any time and the limit sensor will prevent the mount from slewing past a certain point.\u003c\/p\u003e\n\u003cp\u003e5. There are also built-in mechanical hard stops to prevent an instrument 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 worm gear that is spring loaded. The significance of this is it 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 12VDC 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.\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 the CGX-L to have the payload capacity of that of much larger (and 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 full loaded mount head a dream 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 takedown times are exceptionally fast, with large hand-tighten knobs holding the optical tube in place.\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. It works in both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eTo accurately polar align your scope, first do a reasonably-accurate mechanical alignment of the mount on the celestial pole by eye. To make this initial alignment quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. Next, use the mount's standard two-star alignment method to align your scope on the sky. Select a suitable bright star from the NexStar hand control's data base and slew your telescope to the star. A star near the meridian and close to the celestial equator will give the most accurate alignment results. Then, press the Align button on the hand control and select Polar Align: Align Mount from the hand control menu. Your telescope will re-slew to the alignment star and ask you to center it in the eyepiece in order to \"Sync\" on the star. After you sync on the star, your telescope will automatically slew to the position that the star should be at if your mount was accurately polar aligned. Use the mount's altitude and azimuth adjustment knobs to place the star in the center of the eyepiece and press the Align button. That's all there is to it! Your CGE Pro mount is now accurately aligned on the celestial pole.\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. Other software features include: database filter limits, a mount hibernate mode, and user-defined slew limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGPS compatible:\u003c\/strong\u003e In addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive CN16 GPS module) for full GPS (Global Positioning System) satellite accuracy. Once the scope is approximately polar aligned, the 16-channel CN16 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. After the CN16 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 CGX-L go-to mount and the CN16, orienting the scope in time and space on earth and aligning your telescope on the sky becomes almost as easy a task as simply turning on your CGX-L mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-year warranty:\u003c\/strong\u003e All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to

(free from coma and corrected for spherical aberration) EdgeHD high definition\/high contrast Schmidt optics. The advanced EdgeHD optical system uses a dedicated dual-element field flattener lens made from premium Schott optical glass in its central baffle tube to reduce off-axis coma and produce aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography). Even better, those EdgeHD optics are mounted on an observatory-grade Celestron CGX-L go-to German equatorial mount.\u003c\/p\u003e\n\u003cp\u003eIn addition to reduced off-axis coma, the EdgeHD optics deliver an astrograph-quality focal plane more than three times flatter than standard Schmidt-Cassegrains and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see sharp point-like stars to the very edges of some of the largest CCD and DSLR chips available today.\u003c\/p\u003e\n\u003cp\u003eFor the ultimate in brightness and contrast, the CGX-L 1100HD optical tube has state-of-the-art Starbright XLT multicoatings. Its light grasp is almost 1600 times that of even the sharpest dark-adapted eye, revealing to your eye and camera star clusters, nebulas, planets, and galaxies in amazing detail. The Fastar-compatible optical tube even allows imaging down to an incredibly-fast f\/2 focal ratio using optional accessories.\u003c\/p\u003e\n\u003cp\u003eThe Celestron CGX-L 1100HD's CGX-L mount can carry payloads of up to 75 pounds, just under three times the weight of the scope's 27.5 pound 11\" optical tube. This makes this mount\/OTA combination rock-steady, no matter how many heavy visual and imaging accessories you add to the system.\u003c\/p\u003e\n\u003cp\u003eThe scope's advanced NexStar computer hand control makes finding over 40,000 of those stars and objects easy and automatic, so you can spend more time looking at those objects, rather than looking for them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Optical System . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEdgeHD aplanatic Schmidt-Cassegrain optical tube:\u003c\/strong\u003e 11\" aperture (2800mm focal length f\/10). Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations (aplanatic design). The 24\" long aluminum optical tube has a large handle on the rear cell and weighs only 27.5 pounds, making it easy to transport and assemble the scope in the field.

It also increases the contrast on subtle lunar, planetary, and nebula details when compared with a scope with ordinary coatings or multicoatings. For more details, click on the \"Starbright XLT\" icon above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube vents\u003c\/strong\u003e: Two cooling vents on the rear cell allow warm air to be released from behind the primary mirror when the scope is taken out for a night's observing or imaging. This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio. An optional Fastar lens assembly lens replaces the scope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/10 position at the Cassegrain focus at the rear.\u003c\/p\u003e\n\u003cp\u003eUsing the Fastar system and a sub-$1500 Orion Star Shoot Deep Space Imager Pro CCD camera, the 11\" CGE Pro 1100HD will record a wide 141 x 94 arc minute field - a long axis almost five times the diameter of the full moon, an immense field for a scope of this size. To assure repeatability when you switch between Fastar and conventional imaging, the scope's optical tube is opto-mechanically aligned on a laser bench during manufacture so that all components are axially symmetric in any configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirror locks:\u003c\/strong\u003e Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (when moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of the optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design, with a wide 5.8 degree field of view, mounted in a spring-loaded easy-adjust quick release bracket..\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStar diagonal:\u003c\/strong\u003e 2\" first-surface mirror type, with 1.25\" adapter.\u003c\/p\u003e\n\u003cp\u003eEyepiece: premium 2\" 23mm 82° field Axiom (122x), a much higher quality eyepiece than those supplied with competitive scopes. The eyepiece field of view is 0.67° wide, over a third larger than the full moon, and an exceptionally wide field for the 122x magnification.\u003cbr\u003eThis Telescope's Mount . . .\u003c\/p\u003e\n\u003cp\u003eThe German equatorial mount has long been the favored choice of astronomy buffs and astrophotographers because of its stability and portability. It is more stable because the center of gravity is directly over the center of its base, and more portable because it can be broken down into smaller component parts than a fork-mount telescope for easy storage and transportation.\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\u003eCelestron has looked to update the way that people interact with their equipment. This quest has brought out a new EQ Mount Series, the CGX. This particular model in the series is the CGX-L and boasts a 75 pound payload capacity.\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\u003e\u003cstrong\u003eNew features are everywhere in the mount head:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1. Ergonomic handles help you move the 47 pound head with ease. That's right; the head weighs 47 pounds and will carry 75. It is an incredible load to weight ratio.\u003c\/p\u003e\n\u003cp\u003e2. Additional accessory ports built into the dovetail saddle plate of the equatorial head. There are two auxillary 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\u003e3. The dovetail saddle plate is longer for added stability and will also accept both Vixen\/AVX and Losmandy\/Celestron D Style dovetails.\u003c\/p\u003e\n\u003cp\u003e4. There are built in home and limit sensors. The home sensor will take the scope back to its home position at any time and the limit sensor will prevent the mount from slewing past a certain point.\u003c\/p\u003e\n\u003cp\u003e5. There are also built-in mechanical hard stops to prevent an instrument 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 worm gear that is spring loaded. The significance of this is it 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 12VDC 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.\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 the CGX-L to have the payload capacity of that of much larger (and 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 full loaded mount head a dream with a simple twist of the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCounterweight:\u003c\/strong\u003e The CGX-L 1100HD comes with two 22 pound counterweights. Each 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 takedown times are exceptionally fast, with large hand-tighten knobs holding the optical tube in place.\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\u003eAlignment on the sky and go-to accuracy: 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. It works in both northern and southern hemispheres.\u003c\/p\u003e\n\u003cp\u003eTo accurately polar align your scope, first do a reasonably-accurate mechanical alignment of the mount on the celestial pole by eye. To make this initial alignment quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. Next, use the mount's standard two-star alignment method to align your scope on the sky. Select a suitable bright star from the NexStar hand control's data base and slew your telescope to the star. A star near the meridian and close to the celestial equator will give the most accurate alignment results. Then, press the Align button on the hand control and select Polar Align: Align Mount from the hand control menu. Your telescope will re-slew to the alignment star and ask you to center it in the eyepiece in order to \"Sync\" on the star. After you sync on the star, your telescope will automatically slew to the position that the star should be at if your mount was accurately polar aligned. Use the mount's altitude and azimuth adjustment knobs to place the star in the center of the eyepiece and press the Align button. That's all there is to it! Your CGX-L mount is now accurately aligned on the celestial pole.\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. Other software features include: database filter limits, a mount hibernate mode, and user-defined slew limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGPS compatible:\u003c\/strong\u003e In addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive CN16 GPS module) for full GPS (Global Positioning System) satellite accuracy. Once the scope is approximately polar aligned, the 16-channel CN16 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. After the CN16 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 CGX-L go-to mount and the CN16, orienting the scope in time and space on earth and aligning your telescope on the sky becomes almost as easy a task as simply turning on your CGX-L mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-year warranty:\u003c\/strong\u003e All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to

from coma and corrected for spherical aberration) EdgeHD high definition\/high contrast Schmidt optics. The advanced Fastar-compatible EdgeHD optical system uses a dedicated dual-element field flattener lens made from premium Schott optical glass in its central baffle tube to reduce off-axis coma and produce aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography). Even better, those EdgeHD optics are mounted on a rock-solid Celestron CGX-L go-to German equatorial mount.\u003c\/p\u003e\n\u003cp\u003eIn addition to reduced off-axis coma, the EdgeHD optics deliver an astrograph-quality focal plane more than three times flatter than standard Schmidt-Cassegrains and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see sharp point-like stars to the very edges of some of the largest CCD and DSLR chips available today.\u003c\/p\u003e\n\u003cp\u003eFor the ultimate in brightness and contrast, the CGX-L 1400HD optical tube has state-of-the-art Starbright XLT multicoatings. Its 14\" aperture has a light grasp that's nearly 2600 times that of even the sharpest dark-adapted eye (36% greater than a 12\" telescope and almost twice that of a 10\" scope). With an effective light-gathering power equal to that many eyes, the EdgeHD optics of the CGX-L 1400HD can reveal to you faint deep space objects in amazing and subtle detail. The unique Fastar-compatible EdgeHD optics allow very short exposure CCD imaging at a phenomenally-fast f\/2 focal ratio by adding an optional accessory lens, making quick work of recording wide-field images of faint deep space objects. Simply adding an optional accessory lens to the unique Fastar-compatible EdgeHD optics lets you make quick work of recording wide-field images of faint deep space objects by cutting the scope's focal ratio to a phenomenally-fast f\/2. Combine that immense light-gathering power and super-fast focal ratio with the newly-designed Celestron CGX-L go-to German equatorial mount and you have a mount\/OTA combination that is ideal for very serious imaging and visual observing.\u003c\/p\u003e\n\u003cp\u003eThe scope's advanced NexStar computer hand control makes finding over 40,000 of those stars and objects easy and automatic, so you can spend more time looking at those objects, rather than looking for them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Optical System . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEdgeHD aplanatic Schmidt-Cassegrain optical tube:\u003c\/strong\u003e 14\" aperture (3910mm focal length f\/11). Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations (aplanatic design). The optical design is a Sky \u0026amp; Telescope Hot Product for 2010. The 31\" long aluminum optical tube has a large handle on the rear cell and weighs 45 pounds, making it a reasonable task to transport and assemble the scope in the field.

This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio. An optional Fastar lens assembly lens replaces the scope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/11 position at the Cassegrain focus at the rear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirror locks:\u003c\/strong\u003e Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (when moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of the optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design, with a wide 5.8 degree field of view, mounted in a spring-loaded easy-adjust quick release bracket..\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStar diagonal:\u003c\/strong\u003e 2\" first-surface mirror type, with 1.25\" adapter.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eThis Telescope's Mount . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe German equatorial mount has long been the favored choice of astronomy buffs and astrophotographers because of its stability and portability. It is more stable because the center of gravity is directly over the center of its base, and more portable because it can be broken down into smaller component parts than a fork-mount telescope for easy storage and transportation.\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\u003eCelestron has looked to update the way that people interact with their equipment. This quest has brought out a new EQ Mount Series, the CGX. This particular model in the series is the CGX-L and boasts a 75 pound payload capacity.\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\u003e\u003cstrong\u003eNew features are everywhere in the mount head:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1.

Additional accessory ports built into the dovetail saddle plate of the equatorial head. There are two auxillary 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\u003e3. The dovetail saddle plate is longer for added stability and will also accept both Vixen\/AVX and Losmandy\/Celestron D Style dovetails.\u003c\/p\u003e\n\u003cp\u003e4. There are built in home and limit sensors. The home sensor will take the scope back to its home position at any time and the limit sensor will prevent the mount from slewing past a certain point.\u003c\/p\u003e\n\u003cp\u003e5. There are also built-in mechanical hard stops to prevent an instrument 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 worm gear that is spring loaded. The significance of this is it 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 12VDC 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.\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 the CGX-L to have the payload capacity of that of much larger (and 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 full loaded mount head a dream 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 takedown times are exceptionally fast, with large hand-tighten knobs holding the optical tube in place.\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  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. It works in both northern and southern hemispheres.  You can however purchase the optional polar axis finder if you wish.\u003c\/p\u003e\n\u003cp\u003eTo accurately polar align your scope, first do a reasonably-accurate mechanical alignment of the mount on the celestial pole by eye. To make this initial alignment quick and easy, there's a latitude scale and fine adjustment controls in both altitude and azimuth. Next, use the mount's standard two-star alignment method to align your scope on the sky. Select a suitable bright star from the NexStar hand control's data base and slew your telescope to the star. A star near the meridian and close to the celestial equator will give the most accurate alignment results. Then, press the Align button on the hand control and select Polar Align: Align Mount from the hand control menu. Your telescope will re-slew to the alignment star and ask you to center it in the eyepiece in order to \"Sync\" on the star. After you sync on the star, your telescope will automatically slew to the position that the star should be at if your mount was accurately polar aligned. Use the mount's altitude and azimuth adjustment knobs to place the star in the center of the eyepiece and press the Align button. That's all there is to it! Your CGE Pro mount is now accurately aligned on the celestial pole.\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. Other software features include: database filter limits, a mount hibernate mode, and user-defined slew limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGPS compatible:\u003c\/strong\u003e In addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive CN16 GPS module) for full GPS (Global Positioning System) satellite accuracy. Once the scope is approximately polar aligned, the 16-channel CN16 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. After the CN16 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 CGX-L go-to mount and the CN16, orienting the scope in time and space on earth and aligning your telescope on the sky becomes almost as easy a task as simply turning on your CGX-L mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTwo-year warranty:\u003c\/strong\u003e All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to scopes.\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\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e14\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e3910mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e55 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e650x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eComputer GoTo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e243 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eStarBright XLT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.32 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e23mm Luminos\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eEdgeHD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e9x50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e15.3\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\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSupplied Accessories: \u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStarbright XLT fully multicoated Fastar-compatible EdgeHD high definition 14\" f\/11 optics\u003c\/li\u003e\n\u003cli\u003eGo-to fully computerized CGE Pro German equatorial mount with three 22 lb. counterweights\u003c\/li\u003e\n\u003cli\u003eHeavy duty adjustable height metal tripod\u003c\/li\u003e\n\u003cli\u003e40,000+ object computer hand control\u003c\/li\u003e\n\u003cli\u003ePPEC (Permanent Periodic Error Compensation)\u003c\/li\u003e\n\u003cli\u003eRS-232 port for connection to a PC\u003c\/li\u003e\n\u003cli\u003eNexRemote remote telescope control software with RS-232 cable\u003c\/li\u003e\n\u003cli\u003eCCD autoguider port\u003c\/li\u003e\n\u003cli\u003e9 x 50mm finderscope\u003c\/li\u003e\n\u003cli\u003e2\" star diagonal with 1.25\" adapter\u003c\/li\u003e\n\u003cli\u003e2\" 23mm Axiom 82° field eyepiece (170x)\u003c\/li\u003e\n\u003cli\u003e12V DC car battery cord\u003c\/li\u003e\n\u003cli\u003eDust covers.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":40221668278345,"sku":"CGXL14HD","price":8999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/17731.jpg?v=1662967845"},{"product_id":"celestron-11-edgehd-optical-tube-cge-losmandy-dovetail","title":"Celestron 11\" EdgeHD Optical Tube, CGE\/Losmandy Dovetail","description":"\u003cp\u003eThe \u003cem\u003eEdgeHD \u003c\/em\u003ehigh definition flat field optics of this Celestron 11\" EdgeHD optical tube give you a true astrographic-quality big aperture 11\" optical tube at a surprisingly affordable price . . .\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-family: arial, helvetica, sans-serif;

The mount of course supports the SkyPortal WiFi (for your smart devices) as well as the StarSense AutoAlign putting cutting edge control and setup at your disposal.\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.\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. This technology basically gets rid of the need for a polar alignment scope.\u003c\/p\u003e\n\u003cp\u003eThe two supplied 11 pound counterweights lock 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\u003e\u003cstrong\u003eThere are nine motor drive speeds:\u003c\/strong\u003e 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 goto modeling, focusing, and plate solving. You 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 computer control of the smooth and precise CGX 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\u003eAll of the database and mount operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the NexStar computer without affecting your dark-adapted vision. 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.\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 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 a Celestron CGE-style or Losmandy D-plate dovetail slide bar as well as 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. A second lock knob prevents the tube from sliding off the mount should the hand-tighten knob loosen.\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\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2032\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e44 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e480x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eComputerized Go-To\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e105 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eStarBright XLT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.57 arc seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e40mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eEdgeHD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e9x50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e14\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":40481980645449,"sku":"CGX8HD","price":3499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/12055_cgx_8_edgehd_kit_1.jpg?v=1675379349"},{"product_id":"celestron-cgx-equatorial-925-hd-computerized-telescope-12056","title":"Celestron CGX Equatorial 925 EdgeHD Computerized Telescope 12056","description":"\u003cp\u003eThe Celestron CGX925HD telescope puts unique new 9.25\" aperture aplanatic (free from coma and corrected for spherical aberration) EdgeHD high definition\/high contrast Schmidt optics on a precision Celestron CGX go-to German equatorial mount.\u003c\/p\u003e\n\u003cp\u003eThe Celestron CGX Equatorial 925 HD telescope puts unique 9.25\" aperture aplanatic (free from coma and corrected for spherical aberration) EdgeHD high definition\/high contrast Schmidt optics on a precision Celestron CGX go-to German equatorial mount. The advanced EdgeHD optical design - a Sky \u0026amp; Telescope Hot Product for 2010 - has a dual-element field flattener lens made from premium Schott optical glass in its central baffle tube that reduces off-axis coma and produces aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography). And those images will look superb through the supplied ultra-premium 82° field 23mm 2\" Celestron Axiom eyepiece.\u003c\/p\u003e\n\u003cp\u003eIn addition to reduced off-axis coma, the EdgeHD optical system delivers an astrograph-quality focal plane more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see visibly sharp and point-like stars to the very edges of some of the largest CCD and DSLR chips available today.\u003c\/p\u003e\n\u003cp\u003eCelestron's renowned Starbright XLT multicoatings on every optical surface give you maximum light throughput across the widest possible visual and photographic spectrum. The high-contrast CGX925HD's light grasp, more than 1100 times that of even the sharpest dark-adapted eye, reveals star clusters, nebulas, planets, and galaxies in amazing visual and photographic detail. The Fastar-compatible optical tube allows imaging down to an incredibly-fast f\/2 focal ratio using optional accessories.\u003c\/p\u003e\n\u003cp\u003eThe smooth and precise Celestron CGX go-to mount makes finding over 40,000 of those stars and objects easy and automatic.

This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak optical performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio, although without the benefits of the dual-element field flattener built into the scope's baffle tube. An optional Fastar lens assembly lens replaces the telescope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/10 position at the Cassegrain focus at the rear of the scope.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirror locks:\u003c\/strong\u003e Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (while moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of the optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design, with a wide 5.8 degree field of view, mounted in a spring-loaded easy-adjust quick release bracket..\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStar diagonal:\u003c\/strong\u003e 2\" first-surface mirror type, with 1.25\" adapter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEyepiece:\u003c\/strong\u003e premium 2\" 23mm 82° field Axiom (102x), a much higher quality eyepiece than those supplied with competitive scopes.

The CGX isn't just a pretty 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 CGX looks like a cross between the CGEM II and the CGE Pro mount from Celestron. The ergonomically-designed CGX has a fresh, attractive, bold appearance and easier set-up of than earlier EQ mounts. It has been uprated with mechanical and electronic changes to a 55 pound payload capacity. The new design allows for 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\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 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.\u003cbr\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 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 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 a Celestron CGE-style or Losmandy D-plate dovetail slide bar as well as 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. A second lock knob prevents the tube from sliding off the mount should the hand-tighten knob loosen.\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\u003eAperture\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e9.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e2350mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio\u003c\/th\u003e\n\u003ctd class=\"data\"\u003ef\/10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeaviest Single Component\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e44\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHighest Useful Magnification\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e555x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMotorized Controls\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eComputerized Go-To\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e111 lbs.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Coatings\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eStarBright XLT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e0.49 Arc Seconds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplied Eyepiece\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e23mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Type\u003c\/th\u003e\n\u003ctd class=\"data\"\u003eEdgeHD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eView Finder\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e9x50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVisual Limiting Magnitude\u003c\/th\u003e\n\u003ctd class=\"data\"\u003e14.4\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":40481980678217,"sku":"CGX9HD","price":4499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/7974\/9961\/products\/12056_cgx_9.25__edgehd_kit_1.jpg?v=1675379351"},{"product_id":"celestron-cgx-equatorial-1100-hd-f-10-telescope-12057","title":"Celestron CGX Equatorial 1100 EdgeHD F\/10 Telescope 12057","description":"\u003cp\u003eThis Celestron CGX Equatorial 1100 HD Telescope is a large, yet portable, astronomer's dream. The EdgeHD optics excel at astro-photography giving you the edge you have been looking for.\u003c\/p\u003e\n\u003cp\u003eThe Celestron CGX Equatorial 1100 HD telescope puts unique new large aperture 11\" aplanatic (free from coma and corrected for spherical aberration) EdgeHD high definition Schmidt optics on a precision Celestron CGX go-to German equatorial mount. The advanced EdgeHD optical design - a Sky \u0026amp; Telescope Hot Product for 2010 - has a dual-element field flattener lens made from premium Schott optical glass mounted in its central baffle tube. The field flattener reduces off-axis coma and produces aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography). And those images will look superb through the supplied ultra-premium 82° field 23mm 2\" Celestron Axiom eyepiece.\u003c\/p\u003e\n\u003cp\u003eIn addition to reduced off-axis coma, the EdgeHD optical system delivers an astrograph-quality focal plane more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see visibly sharp and point-like stars to the very edges of some of the largest CCD and DSLR chips available today.\u003c\/p\u003e\n\u003cp\u003eCelestron's renowned Starbright XLT multicoatings on every optical surface give you maximum light throughput across the widest possible visual and photographic spectrum. The big aperture CGEM 1100HD's immense light grasp, almost 1600 times that of even the sharpest dark-adapted eye, reveals star clusters, nebulas, planets, and galaxies in amazing visual and photographic detail. The Fastar-compatible optical tube allows imaging down to an incredibly-fast f\/2 focal ratio using optional accessories.\u003c\/p\u003e\n\u003cp\u003eThe smooth and precise Celestron CGX go-to mount, itself a Sky \u0026amp; Telescope Hot Product for 2010, makes finding over 40,000 of those stars and objects easy and automatic. You spend more time looking at celestial objects, and less time looking for them. The CGEM mount combines portability and premium-level performance with a payload capacity of 40 pounds. This makes for very steady imaging and visual observing with the 28 pound 11\" Celestron EdgeHD optical tube.\u003c\/p\u003e\n\u003cp\u003eWith a heaviest single component of only 44 pounds, the CGX11HD makes large-aperture astrographic-quality imaging and visual astronomy not only affordable, but highly portable. Its light weight individual components and easily assembled mount make it easy to set up and enjoy - either in your back yard or at a distant dark sky site. Its superb flat-field reduced-coma optical quality and reasonable price for a really big full-featured computerized go-to mount make this Celestron CGX11HD a telescope that will provide years of affordable use and enjoyment for both the serious observer and the dedicated imager alike.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope's Optical System . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEdgeHD Schmidt-Cassegrain optical tube:\u003c\/strong\u003e 11\" aperture (2800mm focal length f\/10). Built-in dual-element field flattener in the central baffle tube. Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations (aplanatic design). The optical design is a Sky \u0026amp; Telescope Hot Product for 2010. The 24\" long aluminum optical tube has a large handle on the rear cell and weighs only 28 pounds, making it easy to transport and assemble the scope in the field.

Starbright XLT coatings give you visibly higher light transmission for visually brighter deep space images and shorter exposure times during imaging. They also increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with ordinary coatings or multicoatings. For more details, click on the \"Starbright XLT\" icon above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube vents:\u003c\/strong\u003e Two cooling vents located on the rear cell allow warm air to be released from behind the primary mirror when the scope is taken out for a night's observing or imaging. This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak optical performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio, although without the benefits of the dual-element field flattener built into the scope's baffle tube. An optional Fastar lens assembly lens replaces the telescope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/10 position at the Cassegrain focus at the rear of the scope. \u003cbr\u003eUsing the Fastar system and a sub-$1500 Orion Star Shoot Deep Space Imager Pro CCD camera, the 11\" CGEM 1100HD will record a wide 141 x 94 arc minute field - a long axis almost five times the diameter of the full moon, an immense field for a scope of this size. To assure repeatability when you switch between Fastar and conventional imaging, the scope's optical tube is opto-mechanically aligned on a laser bench during manufacture so that all components are axially symmetric in any configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirror locks:\u003c\/strong\u003e Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (while moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of the optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design, with a wide 5.8 degree field of view, mounted in a spring-loaded easy-adjust quick release bracket.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStar diagonal:\u003c\/strong\u003e 2\" first-surface mirror type, with 1.25\" adapter\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEyepiece:\u003c\/strong\u003e premium 2\" 23mm 82° field Axiom (122x), a much higher quality eyepiece than those supplied with competitive scopes.

The CGX isn't just a pretty 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 CGX looks like a cross between the CGEM II and the CGE Pro mount from Celestron. The ergonomically-designed CGX has a fresh, attractive, bold appearance and easier set-up of than earlier EQ mounts. It has been uprated with mechanical and electronic changes to a 55 pound payload capacity. The new design allows for 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\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 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.\u003cbr\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. The mount of course supports the SkyPortal WiFi (for your smart devices) as well as the StarSense AutoAlign putting cutting edge control and setup at your disposal.\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.\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. This technology basically gets rid of the need for a polar alignment scope.\u003c\/p\u003e\n\u003cp\u003eThe three supplied 11 pound counterweights lock 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 goto modeling, focusing, and plate solving. You 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 computer control of the smooth and precise CGX 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\u003eAll of the database and mount operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the NexStar computer without affecting your dark-adapted vision. 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.\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.

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 shortens the amount of time needed for the optics to cool down to ambient air temperature for peak optical performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio. An optional Fastar lens assembly lens replaces the telescope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/10 position at the Cassegrain focus at the rear of the scope.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirror locks:\u003c\/strong\u003e Flexible tension clutches hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (while moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of the optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design, with a wide 5.8° field of view, mounted in a spring-loaded easy-adjust quick release bracket.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVisual back:\u003c\/strong\u003e Removable 1.25\" visual back holds visual accessories such as star diagonal, tele-extender, etc.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStar diagonal:\u003c\/strong\u003e 1.25\" prism type.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEyepiece:\u003c\/strong\u003e 1.25\" 40mm Plössl (51x).

Built-in dual-element field flattener in the central baffle tube. Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations(aplanatic design). The optical design is a Sky \u0026amp; Telescope Hot Product for 2010. The 22\" long aluminum optical tube has a large handle on the rear cell and weighs only 20 pounds, making it easy to transport and assemble the scope in the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStarbright XLT fully-multicoated optics:\u003c\/strong\u003e This high transmission\/high reflectivity optical multicoatings package is applied to all optical surfaces. Starbright XLT coatings give you visibly higher light transmission for visually brighter deep space images and shorter exposure times during imaging. They also increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with ordinary coatings or multicoatings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube vents:\u003c\/strong\u003e Two cooling vents located on the rear cell allow warm air to be released from behind the primary mirror when the scope is taken out for a night's observing or imaging. This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak optical performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio, although without the benefits of the dual-element field flattener built into the scope's baffle tube. An optional Fastar lens assembly lens replaces the telescope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camerais attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/10 position at the Cassegrain focus at the rear of the scope. To assure repeatability when you switch between Fastar and conventional imaging, the scope's optical tube is opto-mechanically aligned on a laser bench during manufacture so that all components are axially symmetric in any configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirror locks:\u003c\/strong\u003e Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (while moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell,these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of theoptical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design,with a wide 5.8 degree field of view, mounted in a spring-loaded easy-adjust quick release bracket.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStardiagonal:\u003c\/strong\u003e 2\" first-surface mirror type, with 1.25\" adapter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEyepiece:\u003c\/strong\u003e A premium 2\" 23mm 82° field Axiom (102x), a much higher quality eyepiece than those supplied with competitive scopes.

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. Set-up 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\u003e\u003cstrong\u003eBalancing the scope:\u003c\/strong\u003e The two sliding 17pound counterweights are locked in place on the counterweight shaft with a single large hand-tighten knob each.

There are 19 fiberoptic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. The NexStar hand control provides a constant and easily-visible illuminated right ascension and declination readout of the scopes position on the sky. This provides much greater accuracy than conventional (and hard to see at night) 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\u003e\u003cstrong\u003eSome NexStar features:\u003c\/strong\u003e New for the CGEMII 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 field flattener reduces off-axis coma and produces aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography). And those images will look superb through the supplied ultra-premium 82° field 23mm 2\" Celestron Axiom eyepiece. \u003c\/p\u003e\n\u003cp\u003eIn addition to reduced off-axis coma, the EdgeHD optical system delivers an astrograph-quality focal plane more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see visibly sharp and point-like stars to the very edges of some of the largest CCD and DSLR chips available today.\u003c\/p\u003e\n\u003cp\u003eCelestron's renowned Starbright XLT multi-coatings on every optical surface give you maximum light throughput across the widest possible visual and photographic spectrum. The big aperture CGEM II 1100HD's immense light grasp, almost 1600 times that of even the sharpest dark-adapted eye, reveals star clusters, nebulas, planets, and galaxies in amazing visual and photographic detail. The Fastar-compatible optical tube allows imaging down to an incredibly-fast f\/2 focal ratio using optional accessories.\u003c\/p\u003e\n\u003cp\u003eThe smooth and precise Celestron CGEM II go-to mount makes finding over 40,000 of those stars and objects easy and automatic. You spend more time looking at celestial objects, and less time looking for them. The CGEM II mount combines portability and premium-level performance with a payload capacity of 40 pounds. This makes for very steady imaging and visual observing with the 28 pound 11\" Celestron EdgeHD optical tube.\u003c\/p\u003e\n\u003cp\u003eWith a heaviest single component of only 44 pounds, the CGEM II 1100HD makes large-aperture astrograph-quality imaging and visual astronomy not only affordable, but highly portable. Its light weight individual components and easily assembled mount make it easy to set up and enjoy - either in your backyard or at a distant dark sky site. Its superb flat-field reduced-coma optical quality and reasonable price for a really big full-featured computerized go-to mount make Celestron CGEM II 1100HD a telescope that will provide years of affordable use and enjoyment for both the serious observer and the dedicated imager alike.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis Telescope'sOptical System . . .\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEdgeHD Schmidt-Cassegrain optical tube:\u003c\/strong\u003e 11\" aperture (2800mm focal length f\/10). Built-in dual-element field flattener in the central baffle tube. Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations(aplanatic design). The optical design is a Sky \u0026amp; Telescope Hot Product for 2010. The 24\" long aluminum optical tube has a large handle on the  rear cell and weighs only 28 pounds, making it easy to transport and assemble the scope in the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStarbright XLT fully-multicoated optics:\u003c\/strong\u003e This high transmission\/high reflectivity optical multi-coatings package is applied to all optical surfaces. Starbright XLT coatings give you visibly higher light transmission for visually brighter deep space images and shorter exposure times during imaging. They also increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with ordinary coatings or multi-coatings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube vents:\u003c\/strong\u003e Two cooling vents located on the rear cell allow warm air to be released from behind the primary mirror when the scope is taken out for a night's observing or imaging. This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak optical performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFastar compatible:\u003c\/strong\u003e For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f\/2 focal ratio, although without the benefits of the dual-element field flattener built into the scope's baffle tube. An optional Fastar lens assembly lens replaces the telescope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f\/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f\/10 position at the Cassegrain focus at the rear of the scope.  \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFocusing:\u003c\/strong\u003e Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the \"mirror flop\" typical of bushing focus mechanisms that causes image shift during critical focusing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMirrorlocks:\u003c\/strong\u003e Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (while moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or chip) no matter what the orientation of the optical tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinderscope:\u003c\/strong\u003e 9 x 50mm straight-through achromatic design, with a wide 5.8 degree field of view, mounted in a spring-loaded easy-adjust quick release bracket..\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStar diagonal:\u003c\/strong\u003e 2\" first-surface mirror type, with 1.25\" adapter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEyepiece:\u003c\/strong\u003e premium 2\" 23mm 82° field Axiom (122x), a much higher quality eyepiece than those supplied with competitive scopes.

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 take down 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.
