• Use Smartphone for Tour of Night Sky
• See Moon, Planets, Nebulae, Galaxies
• 150mm / 5.9" Parabolic Mirror
• 25mm & 10mm Eyepieces
• Dobsonian-Style Alt-Az Base
• Teflon Bearings & Smooth Altitude Brake
• 1.25" Rack & Pinion Focuser
• Can Be Mounted on Optional Tripod

Pairing the simplicity of a Dobsonian with a comprehensive but user-friendly smartphone app, the StarSense Explorer 150mm f/5 Tabletop Dobsonian Telescope from Celestron makes it easy to observe fascinating objects in the cosmos. No computerized mount is needed—simply place your phone in the dock attached to the optical tube, and after a quick alignment, the app will scan the sky and guide you to Jupiter's Great Red Spot, Saturn's rings, the Orion Nebula, and hundreds of other objects. When the bull's-eye on your phone screen turns green, the object is visible in your eyepiece.

Equipped with a 150mm parabolic primary mirror, the telescope can pick out the brighter objects, even when used in a city. A darker location will provide access to many more. The Tabletop Dobsonian is highly portable and can be used on a table, a car hood, or atop an optional tripod.

·         Navigate the sky within minutes of setting up, even with no telescope experience

·         StarSense Explorer app works with most modern smartphones, including iPhone 6 and up, and most devices running Android 7.1.2 or later manufactured since 2016

·         Rather than phone gyroscopes or accelerometers, the app uses a Lost in Space Algorithm to match star patterns it detects overhead to its internal database

·         Audio descriptions and detailed information about thousands of objects within the app's robust database

·         Alt-azimuth base with Teflon bearings and altitude brake permits smooth movement of optical tube for following objects across the sky

·         Optical tube can be adjusted in its cradle for the most comfortable observing position

·         Rack-and-pinion focuser accepts 1.25" eyepieces; 25mm and 10mm Kellner eyepieces included
