Product Description

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.

StarSense Explorer app automatically generates a list of objects currently visible. View planets, brighter nebulae and galaxies, star clusters, and double stars from the city. Or take your telescope to darker skies to view faint, deep sky objects.

Manual altazimuth mount with smooth, dual-axis slow-motion controls makes it easy to follow the on-screen arrows to your desired target. When the bullseye turns green, it’s ready to view in the telescope’s eyepiece.

Dazzling Views with High Quality Optics
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 Jupiter’s four Galilean moons, its cloud bands and Great Red Spot, Polar ice caps on Mars, the rings of Saturn, the trapezium in the Orion Nebula, and beautiful Pleaides Open Star Cluster and much more.

Included
25mm and 10mm eyepieces, Barlow lens, StarSense smartphone dock, erect image diagonal, a red dot finderscope (in case you want to use the telescope without your phone), and a sturdy, full-height tripod.

Magnifications with supplied Eyepieces
40x 80x 100x 200x

Further details

Affordale, simple to use telescope that with just your smartphone and the APP finds objects in the night sky fast - 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.

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.

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") 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 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.

Customer Reviews

Excellent beginner telescope I bought this to attempt to start to see some stars and planets with my young kids. With the smartphone app it took me about 1 hour from unboxing to having it aligned. That night we saw some double stars and Mars! Super easy to use. Excellent customer service from Harrison Telescopes! (17/10/2020) Mr Laurie Richards - Surrey

Absolutely brilliant I am an absolute beginner using telescopes and after days of searching for a telescope that would give decent views but be simple to use I’m really happy that I chose this one. Setting up this evening was pretty simple and within minutes I had a great view of the moon. Detail is amazing. (05/05/2020) Lisa - Hertfordshire

Great scope but app issues The scope is great, setup is easy got some awesome views of the moon. The app I had set up issues with though, it struggled to find the location and I had to re install it, nearly gave up with it but it eventually sprung into life. Great addition having the app when it works, updates may fix this (02/05/2020) Craig - West Yorkshire
