The Orion 180mm Maksutov-Cassegrain (7.1") Maksutov-Cassegrain Telescope optical system has 2,700mm focal length (f/15). With 44% greater light grasp than a 150mm Mak, you'll get brighter images and better resolution. No other optical design can deliver such potent optical specifications in a package that measures just 22" long and weighs in at less than 16 lbs. The meniscus lens is fully multicoated for maximum light transmission, further enhancing image brightness. The visual back accepts 1.25" telescope eyepieces and accessories, and a dovetail bracket on the rear cell accepts any Orion finder telescope or EZ Finder. The dovetail rail on the underside of the tube attaches to your Orion SkyView Pro, Sirius, or Atlas mount.
Our biggest Mak offers the amazing image definition Maks are known for, but with a hefty 7" of aperture for brighter images.
