Celestron StarSense Explorer 130mm Smartphone App-Enabled Tabletop Dobsonian
Unleash the power of your smartphone to take you on a guided tour of the night sky—no telescope experience required.
Patented, award-winning StarSense sky recognition technology uses your smartphone to analyze star patterns overhead and calculate the telescope’s position in real-time.
A 130mm parabolic primary mirror helps you make the most of StarSense technology. Locate faint, deep-sky objects in seconds and see them in more detail than ever before.
A sturdy tabletop Dobsonian-style base that makes it easy to follow the on-screen arrows to your desired target. When the bullseye turns green, it's ready to view in the telescope's eyepiece.
StarSense Explorer Powered by SkySafari™ app automatically generates a list of objects currently visible. View planets, brighter nebulae and galaxies, star clusters, and double stars from the city. Or take your telescope to darker skies to see even more.
Includes a 25mm and 10mm Kellner eyepiece, the StarSense smartphone dock, a StarPointer™ red dot finderscope, an eyepiece rack, and a collimation cap.

Solar Warning
Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
