The Celestron StarSense Explorer 150mm is a tabletop Dobsonian telescope that uses a smartphone to find objects in the night sky. The phone sits in the StarSense dock on the telescope. The app uses patented StarSense Sky Recognition technology to work out where the telescope is pointed.
After a quick alignment of the phone to the telescope's optics, the app lists the celestial objects currently visible. Once you pick one, on-screen arrows guide you as you move the telescope. The bullseye turns green when the object is ready to view in the eyepiece. The app includes hundreds of audio descriptions and detailed information on thousands of objects.
The telescope has a 150mm (5.9") parabolic primary mirror. Its compact, lightweight tabletop base has Teflon bearings for smooth motion in altitude and azimuth, and an altitude brake that adjusts tension. The base has an eyepiece rack and carry handles. It can sit on a stable platform such as a table to raise it to a comfortable height, and an optional tripod can be added.
