    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.

    Celestron NexStar 4SE

    With minimal use, I am very satisfied. I only have minor issues with the owner's manual. These were resolved by a call to OPT.

    Great service

    The celestron 4 se is awesome, easy to use. This is my first telescope and i was able to align it with no issues.

    4se review

    First scope was bad. When I unpacked the scope/ mount, I noticed the badge laying in the box (glue didn't hold). No biggie (or so I thought) as I would just reglue it. So moving on, I set it all up and when I went to look through it, just black Yes, the cap was off :O. When I tried to move the flip mirror (thinking it was in the wrong position), the selector knob had troubles moving. After a few attempts, I heard the flip mirror fall into the OTA. So I called OPT the next day and told them the problem. After they consulted with Celestron, they called me back the next day (now 2 days after I bought it) and told me to bring it back for a replacement (or I could mail it back as I was a 2 hr. drive away), I drove down to save a couple weeks waiting and didn't want the scope broken further or my replacement broken either. I made it back down there a week later and they gave me another scope, which I tried out before making the 2 hr. drive back home. So it seems Celestron had a bad batch of glue when my first scope was made. Second scope seems much better, hope this glue holds up :O . Haven't had time to use it as it has been cloudy most nights (marine layer). I had 1 night that I tried it out and it seemed ok, but not enough time to really evaluate it's optics. That will be another time.

    So far so good

    I was able to put together the Telescope and install the software on my laptop. Because of the season we have not been able to test it yet. The Telescope came with a RS 232 Cable I had to buy a cable from RS 232 to a USB to link to my laptop. I think there should have been a USB instead of RS 232. I am a total novice when it comes to Telescopes since this is my first. I expect to start using it when the warmer weather comes. It is January in North Carolina. Right now I would give it 4 stars. If it does everything it is supposed to do when I get it set up outside I will give it 5 stars. I also purchased the Celestron camera to plan do some astro photography. I am very computer literate since I am a retired Software Engineer. I have always had an interest in Astronomy and want to share this new hobby with my wife.

    NexStar 4SE - 4

    NexStar 4SE

    Just unboxed the scope this evening and tried it out. Purchased for my nine year old son. Very simple to set up and use. Much easier than my Meade LXD55 w/8 SCT. But then it certainly does not show the dim stuff as well. So far, though, I'm quite impressed.
