| The Cassini CC-872 is mounted on an Altitude Azimuth yoke  mount. It's easy use up and down, left and right movement is great for  beginners and casual star gazers alike. Terrestrial viewing is extremely easy  due to the included 45° diagonal which produces a totally erect image. The  Mount features a slow motion altitude adjustment rod for precision adjustments  and is attached to a very sturdy, fully adjustable, pre-assembled metal tripod  with retractable rubber feet. The telescopes optical tube assembly is finished  out with a large 1¼″ format focus tube. The Cassini CC-872 optical tube assembly features a 800mm  focal length. The objective lens is an 72mm two element achromat (color correct  crown & flint) air spaced objective lens. The tube itself is aluminum,  painted flat black internally, and fully baffled for excellent visual and CCD  imaging. The objective is fully multi-coated and has a resolving power of 1.61  arc seconds. The optical tube assembly is diffraction limited at λ4 (1/4 wave  in Sodium light). The diagonal consists of a 45° Schmidt prism that is fully  coated in Magnesium Fluoride (refractive index: n = 1.38). The finderscope is  Galileo’s Mars’ Eye electronic Finderscope which helps by getting the observer  behind the telescope without losing the surrounding field of view when  targeting objects. Included with the CC-872 are a 1¼″ 6mm eyepiece, a 1¼″ 20mm  eyepiece and a 3 element 3x Barlow.
