Celestron designed the AstroMaster 70AZ 70mm f/13 Alt-Az Refractor Telescope as a multi-function starter-scope that can be used for both astronomical and terrestrial viewing. Its medium aperture and long focal length allow it to draw in a generous amount of light with a high magnification potential to allow observation of the larger planets and the moon. The included 90° diagonal has an integrated erecting prism that corrects the view to enable the scope's use on land. Celestron includes two eyepieces for high and medium magnifications.The AstroMaster is outfitted with a manual alt-azimuth mount and to make finding and tracking objects easy, there is an altitude control handle and an azimuth lock. Supporting the mount and optical tube is a stainless-steel tripod with sturdy 1.25" diameter legs and an adjustable height from 24 to 41-inches. Its center accessory tray pulls double-duty as a convenient place to store eyepieces and smartphones while it locks the legs in place to improve stability and reduce vibrations.
