Celestron StarSense Explorer 8 Dobsonian Telescope
Celestron has reinvented the Dobsonian telescope with the StarSense Explorer —the first Dobsonian that uses your smartphone to analyse the night sky and calculate its position in real-time.
This large-aperture Celestron StarSense Explorer is ideal for serious astronomy beginners, thanks to the app's user-friendly interface and detailed tutorials. It's like having your own personal tour guide of the night sky as you pursue your astronomical adventures. This telescope is great for fans of stargazing to make the most of the starry night sky. View planets, brighter nebulae and galaxies, star clusters, and double stars. Connect your smartphone and take a guided tour of the universe.
Leave complicated star charts, imprecise planetarium apps, and computerised mounts behind. With StarSense Explorer, locating objects has never been easier, faster, or more accurate. Within minutes of setting up the telescope, you'll be navigating the sky with confidence. Simply place your phone in the unique StarSense dock and launch the StarSense Explorer app.
After aligning your phone to the telescope's optics, StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear on-screen, guiding you as you move the telescope. When the object is ready to view in the eyepiece, the bullseye turns green. As you observe, listen to hundreds of audio descriptions and view detailed information about thousands of objects within the app’s robust database.
Features:
• 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.
