Description of Orion 8 f/8 Ritchey-Chretien Astrograph Telescope
The Orion 8" Ritchey-Chretien Astrograph's outstanding optical design lets you capture spectacular, detailed images of deep-sky objects like never before. Unlike conventional Newtonian reflector and Schmidt-Cassegrain designs that are susceptible to coma away from the center of the field, the Ritchey-Chretien utilizes hyperbolic primary and secondary mirrors, made of BK-7 optical glass, to achieve wonderfully flat-field images that are virtually coma-free. Images are also free from chromatic aberration, since there are no lenses. The Orion 8? Ritchey-Chretien Astrograph is ideal for use with small CCD-chip cameras such as our StarShoot line, as well as medium-format CCD and DSLR cameras. The telescope?TMs wide, fully illuminated flat field produces pinpoint star clarity all the way to the edge of the camera?TMs sensor. The Orion 8? Ritchey-Chretien Astrograph features a machined, dual-speed (10:1) Crayford-style focuser with an engraved millimeter scale on the drawtube. The secondary mirror is precisely center-marked to facilitate collimation. The 21-inch enameled steel optical tube weighs only 15.8 lbs. and features a Vixen-style dovetail mounting bar underneath, for trouble-free setup on medium or large-sized equatorial mounts. The inside of the optical tube is fortified with eight computer-positioned light baffles, and the primary mirror baffle tube and secondary mirror light shield are also highly baffled to ensure maximum image contrast.
