    Orion 180mm Maksutov Cassegrain OTA

    Orion 180mm Maksutov Cassegrain OTA

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

    The Orion 180mm (7.1 inch) Maksutov-Cassegrain 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 inch long and weighs in at less than 16 lbs. The meniscus lens of the Orion 180mm Maksutov Cassegrain OTA is fully multicoated for maximum light transmission, further enhancing image brightness. The visual back accepts 1.25" eyepieces and accessories, and a dovetail bracket on the rear cell accepts any Orion finder scope or EZ Finder. The dovetail rail on the underside of the tube attaches to your Orion SkyView Pro, Sirius, or Atlas mount.

    The Orion 180 "Big" Mak OTA offers the amazing image definition Maks are known for, but with a hefty 7 inch of aperture for brighter images. One-year limited warranty.
