  • Quality

    I already have a few telescopes and wanted to add another to my collection. This is up to par with the major brands. Overall quality is beautiful and solid. Reminds me of one of my other Celestron telescopes. Great eyepieces, optics and accessories. Pretty quick to assemble and use. This gets an big thumbs up from me. Decent shipping times with Overstock. Will shop here again.

  • Complicated to use
    Verified Purchase

    If we could ever get it to really work, it may have been amazing. We never saw anything. It came with an instructional DVD, which seemed a bit much for a telescope. You had to set coordinates, and do a whole lot of pre work. Definitely not a point and see telescope.

    I bought this for my boyfriend and I must say that he was shocked at the size of the telescope and the quality. I have purchased several items from Overstock and I know I will continue to do so.

  • Star gazing
    Verified Purchase

    Have always wanted to gaze at the stars and now we can. We looked at the recent eclipse of moon and what a beautiful sight! Waiting for some clear night to view the stars. Perfect for a couple of armature star gazers. Easy to set up and operate. Siting in was a little difficult as a 500 yard range was required but other than that it was not too difficult.

    Was look for a telescope that my kids and I could use. This one fits the bill. Not terribly difficult to maneuver although it is a little cumbersome size wise. We still drag it out when the skies are clear! Nice value.

    We live on a beautiful Lake in Tennessee! We watch the stars! We watch the boats on the water! We view the many water fowl that visit! Wonderful Christmas gift for my husband! He views the fisherman on the lake to see what lures they are using! LOL!
