Description
The Celestron Starsense Explorer Dobsonian Telescope - 203mm will 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 analyse star patterns overhead and calculate the telescope's position in real-time.
A large 8" parabolic primary mirror with XLT coatings 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, Dobsonian-style base with large diameter bearings and variable altitude tensioning 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 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 Plssl eyepiece, a 2" Crayford focuser, the StarSense smartphone dock, a StarPointer red dot finderscope, an eyepiece rack, and a collimation tool.
