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's optical systems internal baffling ensures the highest contrast levels. To maintain the company'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'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'll bring the details of bigger apertures without adding to the weight of your rig.

Orion Dual-Speed Crayford Refractor Focuser 2" Product Info The Orion 2" Dual-Speed Crayford Refractor Focuser provides a simple, yet profound performance upgrade for your favorite Orion refractor telescope. The high-quality design adds fine focus adjustment ability with a ratio of 11:1 to your refractor. Eleven turns of the fine focus knob equals one rotation of the coarse adjustment knobs, allowing you to view even the most complex targets with acute precision. You’ll be amazed at how much detail can be coaxed out of celestial and terrestrial targets with the addition of fine-focus control. Crayford style focusers offer smooth, backlash free focus adjustment by virtue of their gear-free design. Friction applied between the focus adjustment axle and a flat surface on the focus drawtube keep focus adjustments precise and accurate. The Crayford style design virtually eliminates focus errors related to backlash and flexure. Since the amount of applied friction is adjustable, even relatively heavy visual or imaging accessories can be used with the 2" dual-speed Crayford Refractor focuser with optimal results. The focuser features a built-in dovetail finder scope base for use with any Orion reflex sight or finder scope, and includes a 2" to 1.25" adapter for use of 1.25" diagonals, eyepieces, and accessories. Attaching the focuser to your Orion refractor is simple, and thorough installation instructions are included.
