Celestron StarSense Explorer 10" Smartphone App-Enabled Dobsonian Telescope (#22471)
The StarSense Explorer 10” Dobsonian is Celestron’s most ambitious reinvention of the classic Dobsonian yet—marrying old-school aperture with cutting-edge app-based navigation. At its core, it’s everything amateur astronomers have always loved about Dobsonian telescopes: generous light-gathering power, rock-solid simplicity, and unbeatable value per inch. But now, it’s wrapped in the intuitive tech of the 21st century. With this telescope, your smartphone becomes a celestial co-pilot—helping you navigate the night sky like a seasoned observer on your very first night out.
Whether you’re brand new to astronomy or returning after a long hiatus, the StarSense Explorer 10” Dobsonian offers a no-fuss, big-view observing experience that’s powerful, approachable, and endlessly rewarding.
Smartphone Meets Telescope: A Seamless Partnership
Celestron’s patented StarSense technology uses your smartphone—not gyroscopes or guesswork—to plate-solve your position in the sky in real time. This is the same algorithmic technology used by orbiting satellites, but now it's available in the palm of your hand. Simply dock your phone, launch the StarSense Explorer app, and follow the arrows on-screen to find the best objects visible from your location. When the bullseye turns green, you're perfectly centered—ready to view.
Unlike traditional GoTo mounts, there are no motors, cords, or clutches to worry about. And unlike old-school star charts, there’s no learning curve. This telescope takes the mystery out of “what’s up” and replaces it with something better: awe.
A Big, Bright 10" Primary Mirror
The heart of the system is a generous 10" (254mm) parabolic primary mirror with a 1200mm focal length, delivering stunning views at a fast f/4.7 focal ratio. With over 1300x the light-gathering power of the human eye, you’ll easily observe the cloud bands and moons of Jupiter, Saturn’s rings, bright emission nebulae like M42, distant galaxies like M31, and more. Under dark skies, this telescope becomes a deep sky powerhouse.
All optical surfaces are treated with Celestron’s StarBright XLT high-reflectivity coatings, which increase contrast and maximize light throughput. The mirrors are crafted from low-expansion optical glass for consistent performance even in varying environmental conditions.
A Mount That’s Built Like a Rock
The Dobsonian base is as solid as it gets—constructed from melamine-coated particle board with reinforcements not often found in this size class. Large altitude bearings provide buttery-smooth movement, and adjustable tension knobs let you fine-tune balance even as you switch between accessories. The Teflon azimuth bearings ensure that sweeping across the sky feels effortless, while the ergonomic front panning knob keeps your hands away from the optical tube (and any unwanted heat currents).
Precision Focus and Versatility
Celestron includes a high-quality 2” Crayford-style focuser with this model. The Crayford design ensures precise, backlash-free focusing for both planetary and deep-sky targets. A 2" extension tube and 2"-to-1.25" adapter are also included, so you can use virtually any eyepiece in your collection.
Perfect for the Backyard or the Backcountry
While the telescope is large enough to deliver truly impressive views, it remains surprisingly portable. The base and optical tube are each outfitted with sturdy carry handles, perfectly balanced for one-person transport. Dust covers for both the primary and focuser openings are also included to keep your optics clean and protected between sessions.
Whether you’re observing from a light-polluted driveway or a dark-sky retreat, the 10” StarSense Explorer Dobsonian opens up a universe of possibilities—and it’s designed to grow with you every step of the way.

Observing Tip
For the best contrast and image quality, allow the primary mirror to thermally equilibrate to outdoor temperatures for 30–45 minutes before observing. A simple aftermarket cooling fan mounted behind the primary mirror can shorten this time dramatically—especially helpful during quick weeknight observing sessions.
