Sky-Watcher 180mm Maksutov-Cassegrain Telescope OTA

This 180 mm (7.08-Inches) Aperture Maksutov-Cassegrain Telescope OTA by Sky-Watcher is a portable scope for its aperture and will impress you with its performance. You could take it along on your next trip to a star party or even on a vacation. Although this telescope is compact in size compared to a Newtonian or refractor, it has the kind of optical quality you expect from a fine Maksutov-Cassegrain OTA. Because it uses the diffraction-limited Maksutov optical system, it produces high-resolution sharp images with high contrast. The optical elements are fully multi-coated to further enhance the image contrast. The aperture of this scope is 180 mm or just over 7-inches for extra light gathering capacity, meaning you will get brighter and sharper images.

With Sky-Watcher's 180 mm Maksutov Cassegrain Telescope focusing is accomplished by turning a knob on the rear housing of the scope, which moves the primary mirror slightly to adjust focus. Focusing is smooth and precise. Your star diagonal and eyepiece never move. Speaking of the star diagonal, this telescope includes a 2-inch 90-degree star diagonal to accept both 2-inch and 1.25-inch eyepieces.

The Sky-Watcher 180 mm Maksutov Cassegrain Telescope comes with a 2-inch 28 mm LET eyepiece. The included 8x50 finder scope makes it easy to find those celestial objects. This 180 mm (7.08-inch) aperture Maksutov-Cassegrain telescope by Sky-Watcher provides a serious aperture for impressive bright images of celestial objects in and out of the solar system, and the long 2700 mm focal length will provide refractor-like contrast. With over 7-inches of aperture and a proven diffraction-limited Maksutov Cassegrain optical system, you will be amazed at the new celestial observations you will accomplish in no time. Begin experiencing the thrill of astronomical discovery now.

You get more than the scope

When you buy from OPT, you get all sorts of helpful info and assistance in the setup, so you don’t get home and find you’re missing some critical element. And in the store you can actually see the item before you get it—unlike some of the online sellers, where you might get an older version or one that’s been kicked around. Hate the drive up to Oceanside, but really glad I live close enough to shop at OPT.
