The StarSense Explorer 130 is a tabletop Dobsonian reflector with a 130mm f/5 mirror and a phone dock that turns your smartphone into a push-to finder. You align the phone to the scope, the app lists what is visible, and on-screen arrows guide you until a bullseye turns green. It suits beginners and casual observers who want to find objects fast without star charts or a computerized mount. Against motorized GoTo scopes it is simpler and quicker to set up, but it relies on your phone and cannot track objects on its own.

Owners and reviewers treat it as one of the easiest beginner scopes to actually use, with the StarSense app doing the finding. The main complaints are the lack of tracking and the reliance on a phone.
The Celestron StarSense Explorer 130mm is a tabletop Dobsonian telescope that uses your smartphone to find objects in the night sky. Place your phone in the StarSense dock and launch the StarSense Explorer app. After a quick alignment of the phone to the telescope's optics, the app generates a list of celestial objects currently visible.
Select an object and on-screen arrows guide you as you move the telescope. When the object is ready to view in the eyepiece, the bullseye turns green. The app includes hundreds of audio descriptions and detailed information on thousands of objects. It uses patented sky recognition technology, with a Lost in Space Algorithm (LISA) that matches the star patterns it detects overhead to its internal database.
The telescope has a 130mm (5.1") parabolic primary mirror and a 1.25" rack-and-pinion focuser. The compact, lightweight tabletop base has Teflon bearings for smooth motion in altitude and azimuth, an altitude brake to adjust tension, an eyepiece rack, and carry handles. The base can sit on a stable surface such as a table, and an optional tripod can be added.
