    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.


    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 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.

    Great First Telescope

    Got this telescope for my son and I to use. It's perfect for what we need. Got a great deal on it from OPT and their team explained to me how to use it including set up as well. Definitely would recommend this to anyone getting into the hobby.

    Plastic parts

    I have this scope. Funny thing , though. The last time I went to use it i noticed that the plastic housing around the secondary on the back of the corrector plate had slightly melted causing the inside of the corrector plate to be totally hazed over with a white coating. Now you may think there is a quite simple explanation to this, but exclude having the scope out to ever view the sun and exclude having the scope out until the sun has almost set. Go figure!

    Good first telescope

    I have wanted a telescope for years and finally decided on this Nexstar telescope. The go-to was pretty easy to use, the telescope is light and easy to move around and everything was able to be set up in just a few minutes. The view through the telescope was very nice and I also use it to look at boats and other daytime targets. I am happy with the telescope.
