Celestron StarSense Explorer LT 127AZ Smartphone App-Enabled Telescope

Celestron StarSense Explorer LT 127AZ Smartphone App-Enabled Telescope Description

Celestron has reinvented the manual telescope with StarSense Explorer, 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 apps user-friendly interface and detailed tutorials. Its like having your own personal tour guide of the night sky.

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, youll 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 telescopes 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.

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.

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 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 phones gyros and accelerometers, which arent as accurate as LISA technology. No other app can accurately tell you when your target is visible in the eyepiece.

StarSense Explorer LTs 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 telescopes pointing position and follow targets as they appear to drift across the night sky. Its all anchored by an adjustable, full-height tripod.

With a large 127mm (5) objective lens, this telescope has enough light gathering ability to bring out detail in celestial objects. You can expect sharp, bright views of Jupiters 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.

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 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 its perfectly portable and easy to bring on your next camping trip or to a remote observing site.

Features
- Unleash the power of your smartphone to take you on a guided tour of the night sky, no telescope experience required.
