StarSense Explorer LT 127AZ Smartphone App-Enabled Newtonian Reflector Telescope
Celestron has reinvented the manual telescope with StarSense Explorer the first telescope that uses your smartphone to analyze the night sky and calculate its position in real time. StarSense Explorer is ideal for 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.
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.
Sturdy Altazimuth Mount
StarSense Explorer LT’s simple altazimuth mount makes it easy to move the telescope to find your target. An altitude slow motion adjustment with a sliding rod helps you fine tune the telescope’s pointing position and follow targets as they appear to drift across the night sky. It’s all anchored by an adjustable, full-height tripod.

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.
