Celestron CGEM II Telescope 

Explore the Celestron CGEM II 1100 EdgeHD Telescope with 11" aperture & Starbright XLT coatings. High magnification, stable mount. Shop now for superior views!

CGEM II 925 HD combines Celestron's newly redesigned CGEM II computerized equatorial mount with its acclaimed EdgeHD optical system. With over 9 inches of aperture and our premium StarBright XLT coatings, the CGEM II 925 HD gives you over 1000 times the light gathering power than the unaided eye. Designed to give diffraction limited performance and offer more resolution than the 800 with less weight than the 1100, the CGEM II 925 HD is a premier astroimaging telescope.  OPTICAL TUBE INFO:  SEE THE UNIVERSE IN HD  EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view.  TRUE ASTROGRAPH QUALITY  Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.  IMPROVED PERFORMANCE  Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron's StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.  MECHANICAL FEATURES  In addition to EdgeHD's optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.  MIRROR CLUTCHES  - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).  TUBE VENTS -  Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.  FASTAR VERSATILITY -  EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens custom-designed for your size EdgeHD tube and you can increase your field of view without sacrificing optical performance. A Barlow lens gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.  INDIVIDUALLY TESTED  Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This "final acceptance test" confirms the EdgeHD will perform in the field and deliver high-quality astroimages.  MOUNT INFO:  A fresh update to the venerable CGEM mount, the CGEM II has a fresh, attractive, bold appearance and is capable of carrying Celestron's higher-end SCT optical tubes (up to 11") securely and vibration free, which is ideal for both imaging and visual observing. Capable of holding 40 lbs. of payload and slewing at 5&#189; per second, you will be able to instantly point to any of the celestial objects in the database.  ERGONOMIC DESIGN  CGEM II was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up.  INNOVATION  The CGEM II series features Celestron's innovative Polar alignment procedure called All-Star All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM II sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings.  PERFORMANCE  For objects near the Meridian (imaginary line passing from North to South), the CGEM II will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM II mount has a robust database with over 40,000 objects, 100 user defined programmable objects and enhanced information on over 200 objects. Celestron's CGEM II mount is the perfect fit between the Advanced Series and CGE Series. Offering the portability of the Advanced Series and the precision of the CGE.

Adorama's service was excellent.  They shipped it within a few days of ordering and it was received in good shape.  The telescope is well designed and well made.  I have been amazed at what this scope can do and I have been able to view and photograph deep sky nebulae  and galaxies I have never been able to capture before.  The tripod and equatorial mount are a bit heavy but very manageable when separately handled.
 It helps to have some basic knowledge of astronomy and telescopes to get the most out of this telescope as there is a learning curve. I would recommend this telescope for anyone who has a 'starter scope' and wishes to upgrade.

Very impressive telescope, good value, good service.

Well built piece of equipment. Looks exactly like in the picture. Upgrades available for the firmware (See Celestron website). The combined weight of this equipment is HEAVY!
