Looking for something to satisfy your appetite for power? Try a big Mak! For the most demanding enthusiast, our Orion 180mm Maksutov-Cassegrain Telescope sets a new standard for superb high-power performance in a remarkably compact design. With 7" of aperture and that long focal length that Maksutov aficionados love, you'll get tack-sharp, high-contrast views and spectacular photographs brimming with subtle detail.

We have upgraded the Orion 180mm Maksutov-Cassegrain with a 2" visual back, so now it accommodates a 2" diagonal and 2" eyepieces (it previously came equipped with just a 1.25" visual back)! What's more, the threads on which the 2" visual back attach are SCT (Schmidt-Cassegrain telescope) threads, which are 2" diameter x 24 TPI male threads. So you can remove the visual back to thread on an optional SCT-specific diagonal or camera adapters designed for SCT threads. Along with the 2" visual back we include a 2" to-1.25" step down adapter to allow use of 1.25" accessories, if desired.

The Orion 180mm Maksutov-Cassegrain (7.1") Maksutov-Cassegrain Telescope optical system has a 2700mm 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. A large rubber-covered focusing knob on the rear sell moves the primary mirror incrementally to enable precise, sharp focus. A dovetail finder base on the rear cell accepts any Orion finder scope or EZ Finder. The Vixen-style aluminum dovetail rail on the underside of the tube provides a solid connection to any compatible mount.

Our biggest Mak offers the amazing image definition Maks are known for, but with a hefty 7" of aperture for brighter images. Whether your passion is visual astronomy or high-power solar system imaging, the newly upgraded Orion 180mm Maksutov-Cassegrain will up your game to the next level of awesomeness!
