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.

• Unleash the power of your smartphone to take you on a guided tour of the night sky - no telescope experience required.
• Award-winning and Patent-pending StarSense sky recognition technology uses your smartphone to analyze star patterns overhead and calculate its position in real time. (Check phone compatibility).
• 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.
• 130mm (5”) Newtonian reflector with highly reflective coatings and enough light gathering ability to view all the best celestial objects.
• Includes 25mm and 10mm eyepieces, StarSense smartphone dock, a red dot finderscope (in case you want to use the telescope without your phone), and a sturdy, full-height tripod.

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 to move the telescope.

When the object is ready to view, the bullseye turns green.

Smartphone Compatibility

StarSense Explorer works with most modern smartphones, including iPhone 6 and up and most devices running Android 7.1.2 or later manufactured since 2016.

Patent-Pending StarSense Sky Recognition Technology

StarSense Explorer uses patent-pending technology and your smartphone to determine exactly where the telescope is pointed in the night sky.

A Lost in Space Algorithm (LISA), like the ones satellites use in orbit to correctly reorient themselves, helps the app match star patterns it detects overhead to its internal database.

While other astronomy apps may claim that they can help you find objects, they rely exclusively on the phone’s gyros and accelerometers, which aren’t as accurate as LISA technology.

No other app can accurately tell you when your target is visible in the eyepiece.
