Celestron Starsense Explorer 150 mm Dobsonian star telescope

Dock, Launch, Explore
Leave convoluted star charts, imprecise planetarium apps and computer-based fixations behind. With StarSense Explorer, locating objects has never been easier, faster or more accurate. Within minutes of mounting the telescope, you can navigate the sky with confidence. Simply place your phone in the unique StarSense dock and launch the StarSense Explorer app.

When the phone is aligned with the telescope's optics (a quick and easy operation), StarSense Explorer generates a list of the celestial bodies currently visible. Make your selection and arrows will appear on the screen to guide you as you move the telescope. When the target is ready to be viewed in the eyepiece, the reticle indicator will turn green. As you observe, listen to hundreds of audio descriptions and view detailed information on thousands of objects in the app's robust database.

High-quality altazimuth stock

The stable Tabletop Dobsonian base provides a solid foundation for the StarSense Explorer. The table stand is compact, light and easy to transport, making it ideal for traveling. The base's low profile makes it easier for some observers (especially children) to access the eyepiece. You can also place the tripod on a stable surface, such as a table or the hood of a car, and raise it to a comfortable viewing height. Consider adding an optional stand for even more viewing options.

Teflon bearings guarantee smooth movement in both height and azimuth. With the help of the integrated height brake system, you can adjust the tension of the height axis so that the movement is as smooth as possible even in small imbalance situations. The panning knob on the telescope tube provides an ergonomic grip, so you can aim the telescope precisely without your hands getting warm to the optical system. When the celestial bodies seem to drift across the night sky, you can follow them easily.

The optical tube is connected to the base using tube rings. The position of the tube in the rings is easy to adjust so that the focuser is in the best viewing position. The stand has an eyepiece holder so that extra eyepieces are always within reach.

Amazing views with excellent optics

Thanks to the large 150 mm (5.9") aperture parabolic primary mirror, this telescope collects enough light to bring out details in celestial bodies. You can expect sharp and clear views of Jupiter's four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the trapezoid of the Orion Nebula and the beautiful Pleiades from an open star cluster.You can make out fine details when looking at the moon and planets, as well as faint galaxies and nebulae.

This telescope features a 1.25" rack focuser that accommodates 1.25" eyepieces and dust covers for the front of the tube and focuser.

**Perfect for city or dark sky locations**

Even if you live in a light-polluted urban location, the Celestron StarSense Explorer 150mm Tabletop Dobsonian is advanced enough to easily pick up Jupiter, Saturn, open star clusters like the Pleiades, double stars like Alberio, the Orion Nebula, the Andromeda Galaxy and many more of the best and brightest celestial bodies.

But if you can move the telescope to even a slightly darker place, more objects will come into view. With this 150mm Dobsonian and a relatively dark sky, hundreds of fascinating subjects are well within your reach.

The StarSense Explorer Tabletop Dobsonian is equipped with carrying handles, so it is easy to transport to the observation site.

Smartphone compatibility

Celestron's StarSense Explorer works with most modern smartphones, including iPhone 6 and newer, and most Android 7.1.2 or newer devices manufactured since 2016.

Patented StarSense sky detection technology

StarSense Explorer uses patented technology and your smartphone to determine exactly where the telescope is pointed in the night sky. The LISA algorithm (Lost in Space Algorithm), the kind used by satellites in orbit to orient themselves correctly, helps the application match the constellations it observes above with its internal database.

While other astronomy apps claim to help you find objects, they rely solely on your phone's gyroscopes and accelerometers, which aren't as accurate as LISA technology. No other application can accurately tell when an object appears in the eyepiece.
