Product Overview
Upgraded Moonlite focuser is included. Original focuser is not included.
Upgraded ADM D-Style dovetail installed.
The AT6RC is designed for coma-free imaging using Deep Sky Imager-type cameras, and DSLRs. The December 2009 issue of Sky & Telescope said the Astro-Tech AT6RC is "a superb match" for the APS-C chips used in many DSLR cameras, "yielding a field almost 1° wide with very good star images in all but the corners of the frame."
Featuring a true Ritchey-Chrétien optical system, this very economical 6" Astro-Tech R-C makes you wonder just what those multi-thousand dollar R-Cs have that makes them cost so much.
This Astro-Tech AT6RC Ritchey-Chrétien astrograph has:
• 6" f/9 true Ritchey-Chrétien hyperbolic mirror optical design
• diffraction-limited or better BK-7 mirrors
• enhanced aluminum optical coatings, overcoated with quartz
• UPGRADED Moonlight dual-speed 2" focuser (original focuser not included)
• 1" and 2" extension rings for fine-tuning the back focus
• Upgraded ADM D-style dovetail rail (Losmandy style)
