StarSense Explorer DX 130AZ Newtonian Telescope 

StarSense Explorer DX 130AZ Newtonian Telescope 

Use your smartphone to explore the night sky with your telescope - you don't need any experience using a telescope

Patent-pending StarSense technology uses your smartphone to analyze star patterns in the sky. It calculates where the telescope is pointing in real time - so it knows which observing object you're targeting at any given time. Check your phone's compatibility here.

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

The manual, azimuthal mount with fine adjustment in two axes makes it easy to follow the arrows on the screen to your desired target. When the crosshairs turn green, the target is already visible in the telescope's eyepiece.

5" (130mm) Newtonian reflector with highly reflective coating and enough light gathering power to spot the best celestial objects.

Includes one each of 25mm and 10mm eyepieces, the StarSense smartphone dock, a finder scope (in case you want to use the telescope without your phone), and a sturdy height-adjustable tripod.


StarSense Explorer Dx 130AZ
Celestron has reinvented the manual telescope with the StarSense Explorer - it's the first telescope that uses your smartphone to analyze the night sky and calculate its position in real time. The StarSense Explorer is ideal for beginners thanks to its user-friendly interface and detailed tutorials. It's like having your own personal guide to the night sky.

Dock, launch, explore
Leave complicated star charts, imprecise planetarium programs, and computer-controlled mounts behind. With StarSense Explorer, finding objects has never been easier, faster, or more accurate. Within minutes of setting up the telescope, you'll be able to navigate the sky with confidence. Simply place your phone in the unique StarSense Dock and launch the StarSense Explorer app. After aligning your phone with the telescope's optics (which is done in two minutes), StarSense Explorer generates a list of currently visible celestial objects. Make your selection, and arrows will appear on the screen to help you move the telescope. When the object is visible in the eyepiece, the crosshairs turn green.

Smartphone Compatibility
StarSense Explorer works with most current smartphones, including iPhone 6 and newer and most devices running Android 7.1.2 or later manufactured since 2016.

 Patent Pending StarSense Sky 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 that used by satellites in orbit to correctly reorient themselves, helps the app match the star patterns it detects with its internal database.

While other astronomy apps claim to be able to help you find objects, they rely solely on the phone's compass, gyroscopes, and accelerometers, which are not as accurate as the LISA technology. No other app can tell you exactly when your target is visible in the eyepiece.

High-quality azimuthal mount with fine adjustment drive
The StarSense Explorer DX's sturdy azimuthal mount offers a robust base. Slip clutches and fine drives in both axes help you fine-tune the telescope to the object and track targets as the Earth rotates away under the night sky. Everything sits on a large, height-adjustable tripod.

Perfect views with high quality optics
With its large 130mm (5") objective, this telescope has enough light-gathering power to see impressive detail in celestial objects. You can expect sharp, bright views of Jupiter's four Galilean moons, its cloud bands, and its Great Red Spot, as well as Saturn's rings or the Trapezoidal stars in the Orion Nebula. Don't miss the beautiful open star cluster of the Pleiades! Highly reflective coating on both the primary and secondary mirrors enhance the view.

Perfect for urban as well as dark locations.
Even if you live in a location with slightly brighter skies with moderate light pollution, the StarSense Explorer is powerful enough to spot Jupiter, Saturn, Venus, the Orion Nebula, double stars, and some more of the most famous celestial objects.

However, if you can move the telescope to a slightly darker location, even more objects will become visible. With this 5-inch Newtonian reflector and relatively dark skies, the Andromeda Galaxy, the globular cluster M13 in Hercules, and many others are easy to spot.

The entire telescope weighs only 8.16 kg, making it perfectly portable and easy to take along on your next camping trip or to a remote observing location.
