Celestron StarSense Explorer 8" Dobsonian Telescope – App
Discover celestial objects more easily with the Celestron StarSense Explorer 8" Dobsonian Telescope. Its large 203mm parabolic primary mirror and XLT reflective coatings provide detailed views of the Moon, planets and brighter deep-sky objects. Using a compatible smartphone, the StarSense Explorer app analyses the night sky and provides guidance as you manually position the telescope. Combining substantial light-gathering capability with intuitive navigation, it is ideal for beginners and astronomy enthusiasts.
Key Features
- 203mm Parabolic Mirror: The large Newtonian reflector gathers light for detailed views of the Moon, planets, star clusters and brighter deep-sky objects.
- XLT Mirror Coatings: Reflective coatings on the primary and secondary mirrors improve light throughput and contrast, supporting clearer observations under suitable skies.
- StarSense Sky Recognition: The app uses a compatible smartphone camera to analyse star patterns and determine telescope positioning, guiding users towards celestial targets.
- Tonight's Best Object List: The app suggests observable celestial targets for your location and provides onscreen arrows for manually locating them.
- Manual Dobsonian Base: Large bearings and adjustable altitude tension provide smooth hand-controlled movement, with no motorised tracking system required.
- 25mm Plössl Eyepiece: The included eyepiece provides 48x magnification through the telescope's 1200mm focal length, suitable for initial observations and finding targets.
- 2" Crayford Focuser: Includes a 2" extension tube and 2"-to-1.25" adapter for compatibility with suitable eyepieces and convenient manual focusing.
- StarPointer Finderscope: The included red-dot finder assists with initial alignment and locating targets without using the app. An eyepiece rack and collimation cap are also supplied.
- App Access and Software: Supplied with the StarSense smartphone dock, unlock code and Starry Night Basic software, enabling guided exploration with a compatible phone.
Ideal For
- Beginners wanting smartphone-guided astronomy.

| 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. |
