The Cassini -2 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  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 1&#; format focus tube. The Cassini -2 optical tube assembly features an 0mm focal length. The objective lens is a mm 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 D imaging. The objective is fully multi-coated and has a resolving power of 1. arc seconds. The optical tube assembly is diffraction limited at 4 (1/4 wave in Sodium light). The diagonal consists of a  Schmidt prism that is fully coated in Magnesium Fluoride (refractive index: n = 1.). The finderscope is Cassini&#;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 -2 are a 1&#; 6mm eyepiece ( apparent field of view), a 1&#; mm eyepiece ( apparent field of view), and a 3 element Barlow.
