This mighty astronomical combination of the CGEM DX Computerized mount with an 11" EdgeHD optical tube assembly (OTA) makes for an amateur astronomer's major upgrade. In a dark sky, a computerized GoTo mount is always a help, especially when intending to do astro-imaging. The CGEM DX is a definite state of the art equatorial mount. New features and adjustments Celestron has implemented in this mount range from tracking performance, a definite win for astro-imagers, to a payload capacity of 50 pounds! But there's even more. There is an advantage for every amateur astronomer. Slewing performance is improved, at 5° per second, meaning the observer can increase the time span and number of objects they can view in a given night. Since, equatorial mounts such as the Celestron CGEM DX are usually ranked at the top for astrophotography performance due to their stability, this makes for a perfect instrument for astro-imaging since this mount doesn't need to be re-aligned subsequently every night due to its "Hibernate function". Aligning can be tricky and sometimes doesn't always result in tremendous or reasonable accuracy, but no worries, Celestron has made sure the CGEM DX Equatorial Mount will be capable of stunning yet easy alignment. The mount is easily adjustable with its altaz knobs to polar align. Aligning the telescope itself is actually very simple with Celestron's AllStar method. All the observer must do is slew the telescope to two stars (avoid Polaris or anything close to the NCP/SCP since they're not good alignment reference points), and let the software calculate. Then, the hand controller will prompt the user to slew to any bright star to analyze its accuracy before their observing session, so the user will know if they need to adjust their altitude and azimuth to align with the celestial pole. The Celestron CGEM DX Mount's hand controller has a database of 40,000 celestial objects as well as information of 200 objects.

Every astronomer knows a good mount is only half the equation to a satisfying observing experience, the optics are another. The 11" OTA that comes in this package features Celestron's own EdgeHD optics, a simple evolution from the traditional Schmidt-Cassegrain design to improve the definition of objects. With an f/10 focal ratio, this OTA is magnificent for planetary and terrestrial observation, and using high power photography in addition with the unbelievable high definition and aberration free effects makes for stunning images all your friends will love! However, deep sky objects are also to die for! With the abnormally large database, the observer can slew to all the Messier and NGC, IC, and Caldwell objects as well as inputting desired coordinates and slewing to them.

  • New aplanatic Schmidt telescope design produces aberration-free images across a wide field of view
  • Mirror tension locks hold the primary mirror in place and reduce image shift
  • Cooling vents allow hot air to be released from behind the primary mirror
  • Fastar compatible for fast f/2 imaging
