All about the Celestron STARSENSE EXPLORER ™ DX 114AZ telescope
Celestron has reinvented the handheld telescope with StarSense Explorer, the first telescope to use your smartphone to analyze the night sky and calculate its position in real time. StarSense Explorer is ideal for beginners thanks to the easy-to-use interface and detailed tutorials in the application. It's like having your own personal night sky tour guide.
Dock, launch, explore
Leave behind complicated star maps, imprecise planetarium applications, and computerized mounts. With StarSense Explorer, locating objects has never been easier, faster or more accurate. Within minutes of setting up the telescope, you will be navigating the sky with confidence. Simply place your phone on the exclusive StarSense base and launch the StarSense Explorer app. After aligning your phone with the telescope's optics (a quick 2-minute procedure), StarSense Explorer generates a list of currently visible celestial objects. Make your selection and arrows appear on the screen, guiding you as you move the telescope. When the object is ready to be seen, the target turns green.
StarSense Explorer works with most modern smartphones, including iPhone 6 and higher and most devices with 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 pointing in the night sky. A Lost in Space (LISA) algorithm, such as those used by orbiting satellites to properly reorient itself, helps the application match the star patterns it detects in its internal database.
While other astronomy apps may claim they can help you find objects, they rely solely on the phone's gyros and accelerometers, which are not as accurate as LISA technology. No other app can accurately tell you when your target is visible in the eyepiece.
High quality altazimuth mount with slow motion control
An ultra-stable altazimuth mount provides a solid foundation for the StarSense Explorer DX. Slip clutches and geared slow-motion controls on both axes help you move the telescope smoothly and zero on your target. When celestial objects appear to move across the night sky, you can follow them just by turning the buttons. Everything is anchored by a full height adjustable tripod.
Dazzling views with high-quality optics
With a large 114mm (4.5”) objective lens, this telescope has enough light gathering ability to bring out detail in celestial objects. You can expect sharp, bright views of Jupiter’s four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the trapezium in the Orion Nebula, and beautiful Pleaides Open Star Cluster.
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 4.5” Newtonian and relatively dark skies, the Andromeda Galaxy, Hercules Open Star Cluster, and so many more are easily within your reach.
The entire telescope kit weighs just 10.4 pounds, so it’s perfectly portable and easy to bring on your next camping trip or to a remote observing site.
