Why we love the Celestron Starsense Explorer 8" Smartphone App Enabled Dobsonian Telescope (22470)
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 and easy procedure), StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear on-screen, guiding you as you move the telescope. When the object is ready to view in the eyepiece, the bullseye turns green. As you observe, listen to hundreds of audio descriptions and view detailed information about thousands of objects within the app's robust database.
High-Quality Altazimuth Base
An ultra-stable Dobsonian base provides a sturdy foundation for StarSense Explorer. It features large diameter altitude bearings with variable tensioning, Teflon azimuth bearings, and braces on the side panels for extra stability (unlike most 8" Dobsonian bases). The altitude bearings provide a smooth up-and-down motion while the integrated altitude "brake" system allows you to adjust the tension along the altitude axis for smoothest motion even with slight imbalances. The panning knob on the telescope tube provides an ergonomic grip so you can precisely point the telescope without introducing heat from your hands into the optical system. As celestial objects appear to drift across the night sky, you'll be able to easily follow them with minor adjustments to the telescope's position.
Dazzling Views with High-Quality Optics
With a large 8" Newtonian reflector optical tube, this telescope has enough light-gathering ability to bring out impressive detail in celestial objects while remaining remarkably portable. You can expect sharp, bright views of Jupiter's four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the gaseous glow of the Orion Nebula, dust lanes in the Lagoon Nebula, and our neighbor galaxy, Andromeda. Compared to the StarSense Explorer DX 130 AZ, the 8" Dobsonian has 240+% more light gathering area, providing better views of faint objects.
All mirror surfaces are coated with our XLT optical coatings to visibly increase contrast and light throughput for brighter views. With XLT, you'll be able to discern subtle details while viewing the Moon and planets, as well as faint galaxies and nebulae. The mirrors are made of low-expansion optical glass, which helps ensure the best images under changing environmental conditions.
This telescope also comes with a high-quality 2" Crayford focuser. The Crayford design provides precise and smooth movements without focus shifting. It also includes a 2" to 1.25" adapter and a 2" extension tube, so you can use virtually any 1.25" or 2" telescope eyepiece with your StarSense Explorer Dobsonian. The focuser also features a thumbscrew so you can lock in the sharpest focus.
Perfect for the City or Dark Sky Sites
Even if you live in a light-polluted city location, the Celestron StarSense Explorer 8" Dobsonian is advanced enough to easily pick out Jupiter, Saturn, open star clusters like the Pleiades, double stars like Alberio, the Orion Nebula, Andromeda Galaxy, and more of the best and brightest celestial objects.
But if you can take the telescope to an even slightly darker location, more objects will become visible. With this 8" Dobsonian and relatively dark skies, hundreds of fascinating objects are well within your reach.
Transporting your StarSense Explorer Dobsonian is easy thanks to the ergonomic carry handles located at the balance point of the tube and base. Dust covers are also included for the front of the tube and the focuser.
Smartphone Compatibility
Celestron 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. For a complete compatibility list, click here.
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.
Enhance Your Setup
Keep your phone charged all night while exploring with your StarSense Explorer by adding the PowerTank Glow 5000 to your must-have accessories (sold separately). This 2-in-1 accessory was made with the StarSense Explorer Dobs in mind, it has a red flashlight PLUS a USB power bank for charging mobile devices in the field. Connect the PowerTank Glow 5000 to the two posts at the front of the StarSense Explorer dock with the included bands so it is held in a convenient location for charging your smartphone while in use.

Customer Reviews
The telescope was delivered in great shape and was fully functional on the first clear sky night. The star-sense ap works well and is a key selling point for the Celestron 8-inch scope. I am impressed at the sharpness of visual images. A Baader 8-24 zoom and 2.25X Barlow work in great combination with the telescope.
Responsive to my questions and concerns regarding the telescope.
Telescope is fine. The app doesn't work on Motorola G7 power phone, even though Celestron had tested it against this model.
Finally got to use it under dark skies at a farm. My brother-in-law had an older go-to-scope. I was be up and running looking at different objects while his was still calibrating/aligning. At one point in the night, his goto feature was completely out of whack and he had to recalibrate again. I just kept searching and looking. The Starsense feature is fantastic. When I look at a star or object, the app shows what I’m looking at. The premade list of things to look at based on my location and time was great. I like the fact that I’m the one (and not a computer/motor) is moving the scope; I feel more involved in the process. I’m seriously considering getting a smaller Starsense scope to take camping with me. I highly recommend this scope.
So happy with my first telescope. Amazing views of the moon and stars. Really enjoying trying out the different eyepieces. The StarSense app makes it so easy for a beginner to start understanding the night sky. Can’t wait to see what else this scope is capable of!
