Traveling with your EclipSmart scope is a breeze; all the components fit comfortably inside the backpack. Upcoming Eclipses 2023 - On October 14, 2023, the famed “Ring of Fire” will encircle a darkened Moon during a spectacular annular eclipse.  This phenomenon occurs when the Moon is too far from Earth to cover the Sun completely. The Sun's corona is not visible during an annular eclipse. 2024 - On April 8, 2024, the Moon will completely cover the Sun during an awe-inspiring Total Solar Eclipse. Observers within the path of totality will witness the sun’s dazzling corona, the “diamond ring” effect, and day turn to night.

Celestron - Starsense Explorer DX 130AZ Smartphone App-Enabled Newtonian Reflector Telescope - Silver/Black

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.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. Smartphone Compatibility, StarSense Explorer works with most modern smartphones; it is compatible with Android 12 and later, as well as iOS 18 and newer, including iPhone XR and newer models. Users with older phones can still use this app, but will not be able to reinstall the app if they uninstall it. 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. High Quality Altazimuth Mount with Slow Motion Control - An ultra-stable altazimuth mount provides a sturdy foundation for StarSense Explorer DX. Slip clutches and geared slow motion controls in both axes help you move the telescope smoothly and zero in your target. As celestial objects appear to drift across the night sky, you’ll be able to follow them with just a few turns of the knobs. It’s all anchored by an adjustable, full-height tripod. Dazzling Views with High Quality Optics. With a large 130mm (5”) objective lens, this telescope has enough light gathering ability to bring out impressive 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 Pleiades Open Star Cluster. Highly reflective coatings on both the primary and secondary mirror enhance the views even more. 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 18 pounds, so it’s perfectly portable and easy to bring on your next camping trip or to a remote observing site. Everything You Need to Observe Immediately. When you unbox your new StarSense Explorer DX, you’ll find: 130mm Newtonian reflector optical tube, StarSense dock for your smartphone, Low powered (25mm) and high powered (10mm) eyepiece, StarPointer red dot finderscope, perfect for using the telescope during the day or without the StarSense Explorer app, Altazimuth mount with slow motion controls, Full-height tripod with an accessory tray to keep you organized.

    Must for star gazing for hikers

    I live in western NC. I go up on the blue ridge parkway allot. I love to star gaze. This is a must have.

    Good Entry Level Telescope

    I bought this for my grandson as a gift. It is solidly built except for the tripod. Tripod is nothing special, but it does work. Great for looking at the moon. Excellent backpack that is great for storage and convenient to take with you on a trip. It's worth it as an entry level telescope.

    Better than expected!

    I gave this a 5 not because it's the best scope of the earth, but because it's a whole lot better than I thought it would be. The paperwork says it's better for viewing terrain (yes, even though it's listed as a telescope) but I think it does a fair job at space viewing as well. Once again, not the best but really good. The 45 degree eyepiece makes it easier. Also, if you are a total amateur like me, it comes with downloads and software for your computer to help you and give you ideas. Perfect little scope.
