Celestron StarSense Explorer 8″ Dobsonian Telescope
This telescope comes with a pre-assembled, adjustable stainless-steel tripod, quick release fork arm, NexStar+ computerized hand control, 127mm Maksutov-Cassegrain optical tube, and lots of bonus accessories.
Celestron has reinvented the Dobsonian telescope with StarSense Explorer—the first Dobsonian that uses your smartphone to analyze the night sky and calculate its position in real-time. This large-aperture Celestron StarSense Explorer is ideal for serious 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. The large aperture will ensure that you won’t outgrow the telescope as you continue on in your astronomical adventures.
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
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.

Solar Warning |
Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
