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.

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.
