Designed as a capable and portable starter-scope, the Celestron AstroMaster 90AZ 90mm f/11.1 Refractor Telescope is a complete observational platform for making detailed observations of the Moon, planets, or comet-hunting. Its manual alt-azimuth mount's locking altitude clutch and adjustable pan-axis tension knob allows users to easily track objects using the locking pan handle with reduced vibrations. 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 low and medium 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.
