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.

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 ( For a complete compatibility list, click here).

Patent-Pending StarSense Sky Recognition Technology

The Celestron STARSENSE EXPLORER™ LT 70AZ 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.

StarSense Explorer LT’s simple altazimuth mount makes it easy to move the telescope to find your target.

A slow-motion altitude adjustment knob 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.

Dazzling Views with High Quality Optics, you can expect sharp, bright views through this 70mm refractor.

Fully coated glass optics provide increased light transmission, enhancing details in celestial objects.

The telescope also includes a 90-degree erect image diagonal, so you can use it during the day to view birds, wildlife, landscapes and more.

Perfect for the City or Dark Sky Sites.

Even if you live in a light polluted city location, StarSense Explorer is advanced enough to be able to pick out Jupiter, Saturn, Venus, the Orion Nebula, double stars and a few more of the most famous celestial objects.

But if you can take the telescope to an even slightly darker location, more objects will become visible.

The entire telescope kit weighs just 7.4 pounds, so it’s perfectly portable and easy to take on your next camping trip or to a remote observing site.
