The Celestron AstroMaster 90AZ is a 90mm refractor on a manual alt-azimuth mount with a pan handle and clutch. It sets up without tools and includes two eyepieces, an erect image diagonal, a StarPointer finderscope, a smartphone adapter, and a Bluetooth shutter release. It suits beginners and casual observers who want a simple, portable scope for the Moon, planets, and bright deep-sky objects. Compared with smaller 70mm refractors, it gathers more light and shows more detail, but it lacks the tracking or goto of motorized mounts.
