Harness the power of your smartphone and join a guided tour of the night sky. No telescope experience is required. The patented, award-winning StarSense sky recognition technology uses your smartphone to analyze star patterns above you and calculate the telescope's position in real-time. A 150mm parabolic primary mirror helps you make the most of the StarSense technology. Locate faint deep-sky objects in seconds and observe them in greater detail than ever before. A stable Dobsonian-style tabletop base allows you to easily guide the arrows on the screen to your desired target. When the target turns green, it can be seen through the telescope's eyepiece. The StarSense Explorer powered by SkySafari app automatically generates a list of currently visible objects. Observe brighter planets, nebulae and galaxies, star clusters, and double stars from the city. Or take your telescope to a darker sky for even more to see. Includes a 25mm and 10mm eyepiece, StarSense smartphone docking station, StarPointer red dot finder, focuser, and collimation cap.
