StarSense Explorer 8" Smartphone App-Enabled Dobsonian Telescope

Product Details

  • 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 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 Plössl eyepiece, a 2” Crayford focuser, the StarSense smartphone dock, a StarPointer™ red dot finderscope, an eyepiece rack, and a collimation tool.

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.
