Included Technology

All-Star Polar Alignment

Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.

Nexremote

This telescope control software replaces the hand control and allows the user to remotely control their Celestron computerized telescope from their personal PC or laptop.

SkyAlign

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

LiFePO4

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

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.

Plenty of power in a handy size

Definitely needs external power; 8 AA batteries are the bare minimum and alignment with just those is problematical. With Celestron's power tank, though, it works great! I bought it for use on the Moon, planets and bright double stars from my light polluted front yard and it's just the ticket for carrying out to the driveway for an hour or two's viewing before bed. Two trips gets everything: scope and tripod, power tank, eyepiece case and a chair. Computer drive is very accurate and with careful alignment almost everything ends up in the field of view of a wide field eyepiece. This scope is a lot of fun and very easy at showing the moon and planets to neighbors.
