The Celestron Advanced C11-SGT is a fully loaded scope with an automated GoTo system all ready for your disposal. It has the CG-5 EQ mount for supreme imagery free of jitters that would make even the best of resolving power irrelevant. This combination of aperture, automation and price is terribly impressive.
After a quick alignment procedure, you'll have an impressive database of 40,000 objects at your disposal: just tell the computerized hand control what you want to observe and the scope will do the rest. There's an optional accessory that aligns the scope with GPS information for the utmost in accuracy; even tiny stars invisible in the finderscope will be nailed the first time!
The StarBright XLT coatings are all that distinguish this offering from the ordinary Advanced C11-SGT. These coatings dramatically decrease the total percentage of light loss incurred by the scope'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 that diminishes this effect and brings the faintest things your scope can resolve into greater detail. They'll bring the details of bigger apertures without adding to the weight of your rig.
