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.
