Our take on the Royal Observatory Greenwich StarSense DX 100 Celestron Telescope

The StarSense Explorer DX 100 is a 102 mm refractor on an alt-azimuth mount that uses your phone to find objects in the sky. You dock the phone, the StarSense app reads the sky through the scope's field of view and tells you which way to push the tube. It is aimed at beginners who want to learn the sky without motors or a computer handset. Against motorized GoTo scopes it is simpler and quicker to set up, but you push it by hand and tracking a planet at high power takes practice.

What reviewers say

Questions and answers

Do I need telescope experience to use it?
No. The StarSense app walks you through finding objects, and you can also use the scope manually with the included finder.
Does it track objects automatically?
No. The mount is manual, so you nudge the tube to follow objects as the sky moves.
What can I see with a 102 mm refractor?
Craters and mountains on the Moon, Jupiter's moons and Saturn's rings, plus brighter star clusters and nebulae from a dark site.
Does it need batteries?
The scope itself has no motors or electronics. The app runs on your phone, so keep it charged.
Can I use it without a smartphone?
Yes. It works as a standard manual refractor with the optical finder.
Is it good for astrophotography?
It is not built for it. The manual alt-azimuth mount suits visual observing, not long-exposure imaging.
Where is the Royal Observatory Greenwich StarSense DX 100 Celestron Telescope cheapest?
At Royal Museums Greenwich Shop, for $408.00, as of our latest check.
