Get ready for some high-power observation and imaging with our new CC8 8" Classical Cassegrain! The Classical Cassegrain design hasnt gotten much play among amateur astronomers because they havent been available except in very large sizes at very high prices. But all that is about to change.
Our 8" f/12 Classical Cassegrain excels for high-resolution lunar and planetary viewing and imaging, and will get you in close on tight deep-sky objects such as globular clusters and planetary nebulas. Its a compelling offering for those wanting serious magnifying capability in a compact form factor. With an optional 10mm eyepiece youre already probing at 240x magnification!
The Classical Cassegrain optical design utilizes a parabolic primary mirror and a hyperbolic secondary mirror, which for the CC8 allow a long, "folded" focal length of 2400mm in a tube just 25" long and weighing under 19 lbs. That means the CC8 is easily supported on a modest-size mount like the Orion Atlas Pro.
Both mirrors are made from thermally stable quartz, with enhanced aluminum coating delivering 96% reflectivity. The 200mm primary mirror is fixed in place so you wont get image shift or mirror flop as from a typical Schmidt-Cassegrain or Maksutov. Focusing is done with a 2" dual-speed (10:1) linear bearing Crayford focuser, which is incredibly rigid under heavy loads. Moreover, the CC8 has no glass on the front end to dew up. Its an open tube with 11 baffles inside to ensure maximum contrast.
Sold as optical tube assembly, the CC8 comes with TWO dovetail finder scope bases, a wide D plate mounting bar on the bottom and slotted V-style mounting bar on top, and three extension rings to allow focus with different visual or imaging combos. Backfocus from the 2" accessory collar is 166mm.
