Product Description

Celestron - 8" SCT Telescope with CGEM II Equatorial Mount

As the larger cousin to the C6-A XLT, the Celestron C8-A XLT has 843x the light gathering power of the human eye which dwarfs smaller telescopes of this scale. As a Schmidt-Cassegrain optical tube assembly, the corrector plate and primary mirrors render a focal ratio of f/10 which makes these type of catadioptric designs excellent for both visual and imaging as well as being compatible with many optical accessories to adjust its field of view and focal length. With the addition of Celestron's own StarBright XLT coatings light transmission has been enhanced as well, making the C8-A XLT great for planetary and terrestrial observing and wide field observing of deep sky objects. One accessory suggested is the Focal Reducer by Celestron (NOT INCLUDED, SOLD SEPARATELY!) will reduce the focal ratio of this optical tube to an f/6.3 which is much faster for observing and imaging deep sky objects, especially when using large pixels on larger CCD chips. For the visual astronomer, they'll be pleased to know this optical tube comes packaged with some accessories including a 25mm eyepieces (for a magnification of 81x), star diagonal, 1.25" visual back, and 6x30 finderscope.

Celestron - CGEM II Equatorial Mount

Celestron has updated the ever popular CGEM mount.  The Celestron CGEM II equatorial mount includes new ergonomic design features, the All Star alignment procedure, and legendary Celestron mount performance.  An instrument capacity of up to 40 pounds allows this mount to carry an 11" optical tube with ease.  

The CGEM II includes extra large Altitude and Azimuth adjustment knobs so you can polar align easily, even in cold weather while wearing gloves. A dual saddle plate will accept both V and D series dovetails. Internal mount wiring keeps the exterior of your mount free from cables and prevents cable tangling or wrapping. Celestron's AllStar polar alignment procedure allows you to use any star in the night sky whether the celestial pole can be seen or not.  The results are accurate polar alignment, tracking, and pointing.  The Celestron CGEM II will track far beyond the meridian for uninterrupted tracking.  Permanent Periodic Error Correction (PEC) will train the mount's worm gears over time to remove natural errors that occur during tracking.  

Included with the Celestron CGEMII is a USB hand controller with over 40,000 objects and 100 user-defined objects plus enhanced information on over 200 objects.  The mount's tripod include height marked adjustable legs so you can quickly setup.   If you were considering a Celestron AVX mount but worried it would be too lightweight, the CGEM II is a perfect fit providing a stable base for larger optical tubes and heavier imaging systems.
