Description

Designed for beginners or as a simple grab-and-go option, Celestron‘s NexStar 90 GT 90mm f/10.1 GoTo Refractor Telescope features a utilitarian 90mmm aperture with a long 910mm focal length. This complete observation rig includes the optical tube assembly, the NexStar computer controller, a motorized mount, an aluminum tripod, two eyepieces, a 90° diagonal, and a red-dot finder. The rack-and-pinion focuser accepts the star diagonal that corrects images vertically for terrestrial use. The two eyepieces produce 46x and 228x magnifications to offer users a range of options for observing the Moon, planets, and bright deep sky objects.

The OTA is mounted on a single-arm motorized alt-az mount. Guiding the mount is the NexStar computer hand controller. Packed with over 40,000 objects and flash updateable via the Internet, the NexStar is loaded with features to help users align and find objects in the night sky, including guided tours, automatic tracking rates for near and deep-sky objects, and multiple slew speeds. Supporting the OTA and mount is an aluminum adjustable height tripod. The entire rig assembles and breaks down without the need for tools, letting you set up faster and start observing sooner.
