Celestron C8-A XLT (CGE) Optical Tube Assembly Product Info Now you can have your own a la carte assemblage of your preferred optical tube and mount.  All Celestron Schmidt-Cassegrain telescopes utilize the multicoated Starbright coatings group.  Highly reflective coatings are used on the mirrors, with anti-reflective coatings employed on the correcting lens for increases in light transmission. Celestron&#39;s optical systems internal baffling ensures the highest contrast levels.  To maintain the company&#39;s mindset as well as to provide consistently high performance and customer satisfaction, all Celestron Schmidt-Cassegrain optical assemblies utilize the same superior optics regardless of their size or configuration. The StarBright XLT coatings are all that distinguish this offering from the ordinary 8" optical tube assembly.  These coatings dramatically decrease the total percentage of light loss incurred by the scope&#39;s system of lenses & mirrors by a measure of 43%!  Light is invariably lost as it passes through lenses or is reflected from mirrors, and this can have a particularly dramatic effect of deep space objects.  StarBright XLT coatings are a highly intensive process which diminishes this effect and brings the faintest things your scope can resolve into greater detail.  They&#39;ll bring the details of bigger apertures without adding to the weight of your rig. <h4><strong>Features:</strong></h4> <ul> <li>8" Schmidt-Cassegrain Optical Tube Assembly</li> <li>Aluminum Optical Tube</li> <li>Celestron&#39;s premium StarBright XLT coatings</li> <li>2032 mm focal length (f/10)</li> <li>25 mm eyepiece included (81x)</li> <li>Visual back allows for use with 1.25" accessories</li> <li>6x30 finderscope to help accurately find objects</li> <li>Star diagonal provides more comfortable viewing position when observing objects that are high in the sky</li> <li>Includes dovetail rail compatible with CGE mount</li> </ul>   <strong>Specifications: </strong> Optical Design Schmidt-Cassegrain Aperture (mm) 203.2 mm (8 in) Focal Length 2032 mm (80 in) Focal Ratio 10 Focal Length of Eyepiece 1 (mm) 25 mm (0.98 in) Magnification of Eyepiece 1 81 x Finderscope 6x30 Star Diagonal 1.25 Optical Tube Aluminum Highest Useful Magnification 480 x Lowest Useful Magnification 29 x Limiting Stellar Magnitude 14 Resolution (Rayleigh) 0.69 arc seconds Resolution (Dawes) 0.57 arc seconds Light Gathering Power (Compared to human eye) 843 x Secondary Mirror Obstruction 2.5 in (64 mm) Secondary Mirror Obstruction by Diameter 31 % Secondary Mirror Obstruction by Area 9.77 % Optical Coatings StarBright XLT Optical Tube Length 17 in (432 mm) Optical Tube Weight 12.5 lbs (5.67 kg) Dovetail Compatibility CGE Mount   <strong>Package Contents: </strong> <ul> <li>Celestron C8-A XLT (CGE) Optical Tube Assembly</li> </ul>
