The Cassini C-1100102MD Catadioptric telescope is among Cassini's most popular telescopes, and for good reason. No where can you find a telescope that is so easy to use, and has so many features with so much quality for the price. Take your Cassini C-1100102MD outside at night, point it north, set the deluxe latitude adjuster to your latitude, turn on the fully motorized mount, and point the telescope at any object in the sky. Congratulations, your Cassini C-1100102MD is now tracking that object through the sky, and will continue to do so all night long!

The Cassini C-1100102MD is mounted on Cassini's fully motorized German Equatorial Mount. The mount is electronically driven in both axis; right ascension and declination. At rest the mount will automatically track to the west at 1x sidereal speed. The included hand box controller controls the scope in all 4 directions and features 4 speeds: 2x sidereal, 8x sidereal, 64x sidereal, and Slew (Slewing moves the scope 3° per second). The electronic mount can be run on battery power (8 AA batteries) or with the included AC adapter. It also features a deluxe latitude adjuster for proper polar alignment. The Mount is attached to a very sturdy, fully adjustable, pre-assembled metal tripod with retractable rubber feet. The tripod also features an accessory tray with slots to place 4 1¼″ eyepieces or lenses. The optical tube assembly attaches to the mount by an adjustable tube clamp which in combination with the adjustable counter balance weights ensures easy fluid movement of the telescope at all times. The telescope features heavy-duty primary and secondary mirror cells and the telescope tube assembly is finished out with a 1¼″ format focus tube.

The Cassini C-1100102MD optical tube assembly features an 1100mm focal length. The Primary mirror is 102mm's in diameter and features a heavy duty mirror cell with push / pull collimation screws. The primary mirror is fully aluminized with 92% reflectivity and has a Silicon Monoxide Quartz overcoat which protects the coating. The 102mm diameter mirror provides a resolving power of 1.14 arc seconds. The secondary mirror has an obstruction of approximately 25% linear (approximately 6% of the total area). The optical tube assembly is diffraction limited at λ4 (¼ wave in Sodium light). 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 Cassini C-1100102MD are a 1¼″ 25mm Astroscopic eyepiece, a 1¼″ 10mm Plössl eyepiece and a 3x 2-element Barlow lens. The 25mm is a 3 element, fully color corrected, modified Rank Kasspheric eyepiece with an apparent field of view of 52°. The 10mm Plössl eyepiece is a 4 element fully color corrected eyepiece with an apparent field of view of 52°.
