The Astro-Tech 12-inch Ritchey-Chretien astrograph (2432 mm focal length, f/8 focal ratio) was purchased by the club and partially funded by MVAS member James Dulak primarily for astrophotography, but also serves as a fine optical instrument for public stargazing events. It features hyperbolic Cassegrain-type two mirror optics, low thermal expansion quartz mirrors, multi-layer dielectric mirror coatings, three built-in cooling fans, two 2-inch extension rings to accommodate various cameras, an external dual speed 3-inch Feather Touch focuser, and dual split hinged mounting rings with 14" Losmandy-style D-plate dovetail rails bolted to the rings. A 3-inch Meade APO refractor guide scope presently sits on top of the AT12RC.

The AT12RC telescope rides on a Losmandy HGM Titan Equatorial Mount with Gemini 2 GOTO, which was generously donated by MVAS member Stan Lopata. It can be controlled from the warm room via computer.

When not in use, the RC telescope is protected by an Ultrex 3-layered breathable fabric cover (Peaks Fabrics, Alberta, Canada) designed and constructed by MVAS member F. Thompson.
