Designed as a capable and portable starter-scope, the Celestron AstroMaster 90EQ 90mm f/11 Refractor Telescope is a complete observational platform for making detailed observations of the Moon, viewing planets, or comet-hunting. Its manual equatorial mount, when properly polar aligned, can easily track objects using the slow-motion cables with reduced vibrations, and easy-to-read setting circles aid in speeding up celestial navigation to known coordinates. The entire rig assembles and breaks down without the need for tools, so users can set up fast and get observing sooner.

This version of the AstroMaster comes with two eyepieces that yield a range of magnifications, and a 90° diagonal that sports an integrated erecting prism to correct images and allow the scope to be used as a conventional spotting scope for terrestrial use. The diagonal also places the user's head in a more comfortable position especially when the OTA is pointed at or near the zenith. An adjustable-height stainless steel tripod supports the mount and optical tube, and comes with a center tray that conveniently holds accessories while improving stability and reducing vibrations.
