About the Orion SkyView Pro 180mm Maksutov-Cassegrain Telescope...
Looking for something to satisfy your appetite for power? Try a big Mak! For the most demanding enthusiast, the new Orion SkyView Pro 180mm Mak-Cass Telescope sets the standard for high-power performance and compact design. With 7" of aperture and that long focal length Orion Telescope Maksutov aficionados love, you'''ll get tack-sharp views and clearly defined astrophotography results with subtle detail and high contrast.
The reason for the outstanding high-power performance is the Orion Telescope 180mm (7.1") optical system with its 2,700mm focal length (f/15). With 44% more light grasp than the 150mm Mak, you'''ll get brighter images and better resolution. And the Maksutov-Cassegrain optical design of the Orion SkyView Pro 180mm Mak-Cass Telescope produces larger images with less telescope eyepiece magnification than other telescopes. It'''s the perfect combination of brightness, contrast, and definition for planets, close double-stars, clusters, and well-defined deep-sky targets.
The visual back incorporated into the Orion SkyView Pro 180mm Mak-Cass Telescope accepts 1.25" telescope 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 makes it easy to remove the Orion Telescope or attach it to the Orion Telescope Mount for easier setup. Attach an Orion CCD Camera StarShoot Solar System Imager and you'''ll capture gorgeous high-resolution color images on your PC!
Power, versatility, portability... if you'''re a serious big Mak telescope fan then the Orion SkyView Pro 180mm Mak-Cass Telescope is the one is for you! Requires external 12-volt power, like the Orion Dynamo Pro (#2307), or an AC adapter.
