Orion Sirius EQ-G GoTo 180mm Maksutov-Cassegrain Telescope

The Orion 180mm Sirius Maksutov-Cassegrain Telescope is designed for the serious big Mak fan. With its massive 7.1" aperture, EQ-G mount with GoTo capabilities, and steel construction tripod, this scope is built to work for you. The Sirius EQ-G also includes a1.25" star diagonal, 9x50 finderscope, two counterweights, and a 25mm Plossl eyepieces to get you started.

The Maksutov-Cassegrain optical design provides high-power performance with a 2,700mm focal length and f/15 focal ratio. The 7.1" (180mm) aperture boasts 44% more light gathering power than the 150mm Mak, resulting in brighter astro 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. The meniscus lens is fully multicoated for maximum light transmission, further enhancing the bright, well-defined images. No other optical design can deliver such potent optical specifications in a package that measures just 22" long and weighs in just under 16 lbs.

The EQ-G mount makes this system effortless to control. This GoTo enhanced equatorial mount is a simple yet reliable (and very high-tech) way to control your telescope. Two stepper motors on the Sirius mount power the telescope to the object you select at a brisk 3.4° per second, putting it right in your 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 you're ready to go!

The legendary Sirius EQ-G mount provides a steady base no matter how rugged your viewing conditions are. This substantial mount features internal dual-axis stepper motors that slew the telescope at up to 3.4° per second. Includes an illuminated polar-axis scope, 8.3" dovetail mounting bar, and an 11 lb. counterweight. The tripod is remarkably sturdy with 1.75"- diameter stainless steel legs and metal spreader plate. And, of course, the computerized GoTo controller makes harnessing all that power a snap! Requires an external 12-volt power source or an AC-to-DC adapter.

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 makes it easy to remove the telescope or attach it to the mount for easier setup. Attach an Orion StarShoot Solar System and you'll capture gorgeous high-resolution color images on your PC!
