Royal Observatory Greenwich StarSense DX 100 Celestron Telescope
Celestron has reinvented the manual telescope with StarSense; the first telescope that uses your smartphone to analyse the night sky and calculate its position in real time. Unleash the power of your smartphone to take you on a guided tour of the night sky; no telescope experience required. This edition of Celestron StarSense is ideal for 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.
Celestron StarSense DX 100 is advanced enough to be able to pick out Jupiter, Saturn, Venus, the Orion Nebula, double stars, and a few more of the most famous celestial objects. If you can take the telescope to an even slightly darker location, more objects will become visible.
With this 4” refractor and relatively dark skies, the Andromeda Galaxy, Hercules Open Star Cluster, and so many more are easily within your reach. With a large 100mm (4”) objective lens, this telescope has enough light gathering ability to bring out impressive detail in celestial objects. You can expect sharp, bright views of Jupiter’s four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the trapezium in the Orion Nebula, and beautiful Pleaides Open Star Cluster. Celestron’s XLT optical coatings improve light transmission, enhancing the views even more. The telescope also includes a 90-degree erect image diagonal, so you can use it during the day to view birds, wildlife, landscapes, and more.
The entire telescope kit weighs just 13.5 pounds, so it’s perfectly portable and easy to bring on your next camping trip or to a remote observing site.
- Award-winning and patented StarSense sky recognition technology uses your smartphone to analyse star patterns overhead and calculate its position in real time.
- StarSense Explorer app automatically generates a list of objects currently visible. View planets, brighter nebulae and galaxies, star clusters, and double stars from the city. Or take your telescope to darker skies to view faint, deep sky objects.
- Manual altazimuth mount with smooth, dual-axis slow-motion controls makes it easy to follow the on-screen arrows to your desired target. When the bullseye turns green, it’s ready to view in the telescope’s eyepiece.
- 100mm (4”) refractor with fully coated optics and enough light gathering ability to view all the best celestial objects.
- Includes 25mm and 10mm eyepieces, StarSense smartphone dock, erect image diagonal, a StarPointer™ red dot finderscope (in case you want to use the telescope without your phone), and a sturdy, full-height tripod.
- Celestron in association with the Royal Observatory Greenwich.

- 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.
