Included Technology


SkyAlign alignment technology makes setting up a computerized telescope simple, fast, and accurate. Just point the telescope at any three bright objects — stars, bright planets, or even the Moon — and your telescope can orient itself with the night sky.

Compatible Technology


The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.

Starsense Technology

Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!


WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.
