Celestron Starsense Explorer 150mm Dobsonian Smartphone App-Enabled Telescope

Celestron has reinvented the Dobsonian telescope with StarSense Explorer—the first Dobsonian that uses your smartphone to analyze the night sky and calculate its position in real-time. This large-aperture Celestron StarSense Explorer is ideal for serious 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. The large aperture will ensure that you won’t outgrow the telescope as you continue on in your astronomical adventures.

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 and easy procedure), StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear on-screen, guiding you as you move the telescope. When the object is ready to view in the eyepiece, the bullseye turns green. As you observe, listen to hundreds of audio descriptions and view detailed information about thousands of objects within the app’s robust database.

Smartphone Compatibility

Celestron 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.

Patented StarSense Sky Recognition Technology

StarSense Explorer uses patented 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 orient 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.

Note for Reflectors:

Reflectors have 2 mirrors. The alignment between the 2 mirrors (collimation) is of utmost importance! The new telescopes come collimated form the factory, however, if you make any changes or adjustments in any of the screws around/ behind the primary mirror and and those behind the secondary mirror or those holding the spider, the mirrors will go out of alignment with each other and the telescope will require collimation again. Note that collimation is a DIY process, no other persons or dealers will do it. Although it is part and parcel of using a reflector telescope, it can be quite a tedious process. If you are a beginner/ first time telescope user, please refrain from turning/ opening/ adjusting any screws on the telescope other than those controlling the mount and the focuser. Note that sometimes opening up parts of the telescope may also lead to voiding the warranty of the product!
