StarSense Smartphone App-Enabled Telescope!
Unleash the power of your smartphone and enjoy a guided tour of the night sky—no prior telescope experience required. With award-winning, patented StarSense sky recognition technology, your phone analyzes overhead star patterns in real time to calculate its exact position and guide you effortlessly to celestial targets. The StarSense Explorer Powered by SkySafari™ app automatically generates a list of objects currently visible, from planets, bright nebulae, galaxies, star clusters, and double stars in the city to fainter deep-sky treasures under darker skies.
A smooth manual altazimuth mount with dual-axis slow-motion controls makes following the on-screen arrows simple and precise—when the bullseye turns green, your target is ready in the eyepiece. The 5" Schmidt-Cassegrain optical tube with StarBright XLT coatings delivers impressive light-gathering power and crisp views of the sky’s most popular objects. Complete with 25mm and 10mm eyepieces, a StarSense smartphone dock, red dot finderscope, erect image diagonal, and a sturdy full-height tripod, this system includes everything you need to start exploring right out of the box.
Smartphone Compatibility
StarSense Explorer works with most modern smartphones; it is compatible with Android 12 and later, as well as iOS 18 and newer, including iPhone XR and newer models. Users with older phones can still use this app, but will not be able to reinstall the app if they uninstall it. For a complete compatibility list, click here.
Dock, Launch, Explore
Skip complicated star charts, confusing apps, and pricey computerized mounts. With StarSense Explorer, finding celestial objects is fast, simple, and incredibly accurate. Just dock your smartphone, launch the app, and complete a quick two-minute alignment. The app generates a list of visible targets and displays on-screen arrows to guide your telescope—when the bullseye turns green, your object is ready to view.
Sky Recognition Technology
StarSense Explorer combines patented technology with your smartphone to determine exactly where your telescope is pointed. Using a Lost in Space Algorithm (LISA)—the same type of pattern-recognition system used by orbiting satellites—the app matches visible star patterns to its internal database for precise alignment. Unlike other astronomy apps that rely only on a phone’s gyros and accelerometers, StarSense Explorer delivers true accuracy and confirms when your target is centered in the eyepiece.
High Quality Alt-Azimuth Mount with Slow Motion Control
An ultra-stable altazimuth mount provides a sturdy foundation for StarSense Explorer DX. Slip clutches and geared slow motion controls in both axes help you move the telescope smoothly and zero in your target. As celestial objects appear to drift across the night sky, you’ll be able to follow them with just a few turns of the knobs. It’s all anchored by an adjustable, full-height tripod.
Dazzling Views with High Quality Optics
Featuring a compact 5" Schmidt-Cassegrain optical tube—Celestron’s trusted design for over 50 years—this telescope delivers impressive light-gathering power in a portable package. Enjoy crisp views of Jupiter’s moons and cloud bands, Saturn’s rings, the Orion Nebula’s Trapezium, and the Pleiades star cluster. Fully multi-coated with StarBright XLT optical coatings, it enhances contrast and light transmission for brighter deep-sky views and sharper detail on the Moon, planets, galaxies, and nebulae.
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. With this 5” Schmidt-Cassegrain and relatively dark skies, the Andromeda Galaxy, Hercules Open Star Cluster, and so many more are easily within your reach.
