Celestron - Starsense Explorer LT 114AZ Telescope App-Enabled Newtonian Reflector Telescope - Silver/Black

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; 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. 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. Sturdy Altazimuth Mount, StarSense Explorer LT’s simple altazimuth mount makes it easy to move the telescope to find your target. An altitude slow motion adjustment with a sliding rod 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 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 Pleiades 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.Everything You Need to Observe Immediately. When you unbox your new StarSense Explorer LT, you’ll find:114mm Newtonian reflector optical tube, StarSense dock for your smartphone, Low powered (25mm) and high powered (10mm) Eyepiece, 2x Barlow lens to double the power of each eyepiece, StarPointer red dot finderscope, perfect for using the telescope during the day or without the StarSense Explorer app, Altazimuth mount with slow motion control rod, Full-height tripod with an accessory tray to keep you organized

    Not worth it

    Extremely disappointed. I wasn't hoping for much, but this..ugh. first off, the instructions are horrible. Take it from the person who puts together boxed furniture. Second, i can see the stars better with my phone. Third, the company said put the telescope together wrong. I was mad that the nat geo logo was upside down. Then i was mad the cap didnt fit. Turns out, that how they put it together. I was able to flip it, but i feel like thay could be why i just wasted 100 bucks on a Christmas gift. Just dont bother with this.

    National Gro Telescope.

    We received this after Christmas. A part was broken so I called the company but no answer. I went online to request replacement. Yesterday, I received parts that were not needed or requested. I’m thinking about returning it.
