The StarSense Explorer LT 127AZ allows you to explore the universe without the need for complicated star charts or imprecise planetarium apps. The LT 127AZ allows you to use your smartphone to analyze the night sky and calculate its position in real-time.
The telescope is easy to set up and use in minutes. Simply place your smartphone into the StarSense dock, launch the StarSense Explorer app and you are ready to go.
This telescope is perfect for beginners looking to start their journey into astronomy.
Celestron StarSense Explorer LT 127AZ Specifications
Key Features:
- Unleash the power of your smartphone to take you on a guided tour of the night sky—no telescope experience required.
- Award-winning and patent-pending StarSense sky recognition technology uses your smartphone to analyze star patterns overhead and calculate its position in real-time.
- 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.
- 127mm (5”) Newtonian reflector with highly reflective coatings and enough light-gathering ability to view all the best celestial objects.
- Includes 25mm and 10mm eyepieces, a 2x Barlow Lens, a StarSense smartphone dock, a red dot finderscope (in case you want to use the telescope without your phone), and a full-height tripod.
Exploring the universe has never been easier!
The LT 127AZ is incredibly easy to set up so that you can start observing the night sky right away. The telescope and adjustable tripod weigh in at just 11.4lbs making it easy to take this with you anywhere.
All you have to do is place your smartphone in the StarSense dock and launch the StarSense Explorer app. It only takes 2 minutes to align your phone to the telescope’s optics and then the StarSense Explorer app will produce a list of celestial objects currently visible.
Then all you have to do is select an object that you wish to view and arrows will appear, on your phone screen, to help guide you towards it. The bullseye will turn green when the object is ready to view.
Let LISA be your guide
The StarSense Explorer app allows your smartphone to determine exactly where the telescope is pointed in the night sky. The app uses the LISA (Lost In Space Algorithm), just like is used for satellites in orbit to correctly orient themselves and to match star patterns.
Other apps that claim they can do this only use the phone’s gyros and accelerometers, which are nowhere near as accurate as LISA technology.
Ultra-stable Altazimuth Mount with Slow Motion Control
The LT 127AZ boasts a sturdy foundation thanks to its ultra-stable altazimuth mount. The telescope is equipped with slip clutches and geared slow-motion controls to allow it to move smoothly while zeroing in on the object you wish to observe.
You will be able to track objects across the night sky with just a turn of a few knobs and it is all anchored by an adjustable, full-height tripod.
Impressive detail
The telescope has a large 5" objective lens that is capable of producing enough light-gathering ability to be able to view impressive detail in celestial objects. It is possible to get 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 the beautiful Pleiades Open Star Cluster. Highly reflective coatings on both the primary and secondary mirrors enhance the views even more.
Can be used anywhere
The LT 127AZ can be used in even light-polluted city locations, thanks to the StarSense Explorer app. It is advanced enough to be able to pick out Jupiter, Saturn, Venus, the Orion Nebula and double stars, as well as other famous celestial objects.
If you have the ability to be able to take the telescope to an even slightly darker location, more objects will become visible, such as the Andromeda Galaxy, Hercules Open Star Cluster, and so many more are easily within your reach.
The entire kit weighs only 11.4lbs, making it portable enough to take with you anywhere.
Smartphone Compatibility
The StarSense Explorer app works with most modern smartphones, including iPhone 6 and up and most devices running Android 7.1.2 or later manufactured since 2016. Celestron Explorer Smartphone Compatibility.

FAQ:
Is the StarSense Explorer app compatible with my smartphone?
The app is compatible with most modern smartphones: Celestron Explorer Smartphone Compatibility.
The phone dock on the StarSense Explorer DX mount does not appear to be installed correctly. What’s wrong?
The phone dock’s saddle on the StarSense Explorer DX mount is rotated 180 degrees for shipping to keep the screw from damaging the box in transit. You just need to rotate the saddle 180 degrees by hand so that the phone bracket is right side up. This will also make the saddle the correct orientation with the screw on top. Take off the bracket and scope for now and use the dovetail screw as a handle in the joint between your thumb and pointer finger. Apply pressure until you can rotate the screw up to the top. Now mount the phone dock and telescope and everything will work as it is supposed to.
Solar Warning
- Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
- Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
- Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
