Celestron StarSense Explorer LT 127AZ For Smartphone
Celestron are innovators and they have reinvented the manual telescope with their new StarSense Explorer range — the first telescope that uses your smartphone to analyse 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 computerised 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, see the compatibility tab.
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.
Sturdy Altazimuth Mount: 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: With a large 127mm (5”) mirror, 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. However, if you can take the telescope to an even slightly darker location, more objects will become visible. With this 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 11.4 pounds, so it’s perfectly portable and easy to bring on your next camping trip or to a remote observing site.
