About the Orion SkyView Pro 180mm GoTo 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 GoTo Mak-Cass Telescope sets the standard for high-power performance and compact design. With 7 inces of aperture and that long focal length Mak aficionados love, you'''ll get tack-sharp views and clearly defined astrophotography results with subtle detail and high contrast. And with GoTo motorized computer guidance you can automatically point the Orion Telescope to any of 42,900 celestial objects in the controller'''s database. Just select an object to view from the user-friendly menus on the hand controller and let GoTo do the rest!
The reason for the outstanding high-power performance of the Orion SkyView Pro 180mm GoTo Mak-Cass Telescope is the 180mm (7.1") optical system with its 2,700mm focal length (f/15). With 44% more light grasp than the 150mm Mak Orion Telescope, you'''ll get brighter images and better resolution. And the Maksutov-Cassegrain optical design produces larger images with less 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.
And all that power is so easy to control! The Orion SkyView Pro 180mm GoTo Mak-Cass Telescope GoTo is a simple yet reliable (and very high-tech) way to control your Orion Telescope. Two stepper motors on the SkyView Pro Orion Telescope Mount power the telescope to the object you select at a brisk 3.4 degrees per second, putting it right in your telescope eyepiece''s field of view. You will enjoy more productive viewing sessions, seeing way more wonders in a single evening than you ever thought possible. The GoTo system will even take you on a guided sky tour of the best sights each month! Just do an easy initial alignment, and then you'''re ready to go!
The visual back incorporated into the Orion SkyView Pro 180mm GoTo 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 Maksutov fan then the Orion SkyView Pro 180mm GoTo Mak-Cass Telescope is the one is for you! Requires external 12-volt power or an AC adapter.
For owners of the SkyView Pro EQ GoTo Orion Telescope Mount whose version of the GoTo hand controller is 3.0 or greater, the GoTo hand controller'''s firmware can be updated over the internet.
