Celestron StarSense Explorer 114mm Tabletop Dobsonian Telescope (#22480)
Smartphone-guided stargazing in a lightweight, go-anywhere package.
The Celestron StarSense Explorer 114mm Tabletop Dobsonian is your perfect first telescope—compact, powerful, and refreshingly easy to use. This modern twist on the classic Dobsonian introduces Celestron’s award-winning StarSense Explorer technology to an ultra-portable 4.5" reflector. With real-time sky recognition powered by your smartphone, finding celestial objects is no longer a guessing game. It’s guided, intuitive, and remarkably fun.
Big Sky Adventures Start Here
The 114mm StarSense Explorer isn’t just a telescope—it’s a guided tour of the universe waiting to happen. With a simple setup and no experience necessary, you’ll be observing Saturn’s rings, the Orion Nebula, and even the Andromeda Galaxy within minutes of stepping outside.
Using patented StarSense technology and the SkySafari-powered app, your smartphone becomes a celestial navigator. Place your phone in the included StarSense dock and launch the app. The system scans the sky overhead and calculates the telescope’s real-time position using the same LISA (Lost in Space Algorithm) tech used by orbiting satellites. Follow the on-screen arrows, and when the bullseye turns green, your object is ready to view.
No motors, no alignment stars, and no need to memorize constellations—just dock, launch, and explore.
Sharp, Wide-Field Optics in a Portable Package
Despite its travel-friendly size, the StarSense Explorer 114mm delivers impressive optical performance. The 114mm (4.5") parabolic primary mirror gathers enough light to reveal brilliant lunar details, Saturn’s rings, Jupiter’s moons, the bright core of the Orion Nebula, and more. With a fast f/4 focal ratio, the scope excels at wide-field views, making it easier to locate and frame extended objects like the Pleiades or the Milky Way's star clouds.
You’ll receive two 1.25" Kellner eyepieces: a 17mm for 26x magnification and a 10mm for 45x. The 1.25" rack-and-pinion focuser accepts a wide range of standard eyepieces if you decide to expand your accessory kit later.
Sturdy, Smooth Tabletop Mount
The tabletop Dobsonian base is compact but thoughtfully engineered. Built with Teflon bearings and an altitude brake system, it provides smooth manual tracking and allows you to adjust tension for a balanced feel. Whether you’re following a planet across the sky or nudging toward a faint galaxy, motion remains fluid and intuitive.
The tube sits in a cradle mount, allowing you to reposition the tube’s angle for optimal eyepiece comfort. A built-in eyepiece rack and carry handles make it practical for backyard use or mobile setups—perfect for kids, classrooms, or campouts.
Weighing just 12.6 lbs total, it’s one of the lightest complete telescopes in its class, making it an ideal grab-and-go scope for anyone with limited storage or transportation space.
Your App-Powered Observatory
The StarSense Explorer app doesn’t just point the way—it teaches. Choose from curated observing lists based on visibility, difficulty, or object type. The app includes audio tours, celestial lore, and deep dives into object data for a richer experience. You’ll spend more time looking up and less time looking things up.
Observing Tip:
For best results, use the scope on a low, stable surface like a camp table or tailgate. If you’re sharing the scope with kids or seated observers, its low eyepiece height is ideal. For taller adults, placing the base on a short crate or stackable platform will bring the view to a more comfortable height.
Final Thoughts
The Celestron StarSense Explorer 114mm Tabletop Dobsonian is a delightful combination of quality optics, compact design, and game-changing guidance. It removes the intimidation factor for beginners while delivering real views of the night sky. If you want an affordable, portable telescope that’s smart enough to teach you the sky and powerful enough to keep you coming back for more—this one’s a winner.
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.
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.
