Dock, Launch, Explore

Leave complicated star charts, imprecise planetarium apps, and computerized 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 (a quick, 2-minute procedure), StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear onscreen, guiding you as you to move the telescope. When the object is ready to view, the bullseye turns green.

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 view faint, deep sky objects.

Manual altazimuth mount with smooth, dual-axis slow-motion controls 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.

Dazzling Views with High Quality Optics

With a large 127mm (5") objective lens, this telescope has enough light gathering ability to bring out detail in celestial objects. You can expect sharp, bright views of Jupiter’s four Galilean moons, its cloud bands and Great Red Spot, Polar ice caps on Mars, the rings of Saturn, the trapezium in the Orion Nebula, and beautiful Pleaides Open Star Cluster and much more.
