about this item
The Cassini CC-872EFS 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 erect image prism 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 inch format focus tube.
The Cassini CC-872EFS features our unique Electronic Wireless Focuser enabling the user to focus the telescope without touching it for improved image viewing. The objective lens is an 72mm two element achromat (color correct crown & flint) air spaced objective lens and the optical tube assembly features a 800mm focal length. 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 Î»4 (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 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 CC-872EFS are an 1¼-inch10mm Plössl eyepiece and an 1¼-inch
25mm Astroscopic Eyepiece, and a 2 element 3x Astroscopic Barlow.
