      Another amazing product I actually bought for our children/ but I seem to use it more whenever possible. This telescope just amazingly shows everything in our atmosphere, in the sky. We just cannot "get enough" star gazing. It shows beautiful things that our naked eye is simply not able to see. Hours go by watching through my telescope eyes; it truly feels like minutes, seriously. I've seen unknown drones, things flying through the unknown skies, falling stars ( amazing ) , saucers with unexplainable lights.. At this price ( Thank you Overstock )you're getting educated and having fun doing it! Have fun my friends. krissy

      This was well worth the price. I have it to my son for his birthday and he has had a great time with it. I would recommend it for anyone interested in using telescope as a beginner. It is simple to use but would probably meet all the needs of an amateur astronomer, like my son.

      I bought this as a gift for someone and he loved it. It works great and is also nice to look at so he kept it out in the corner of the room.

    • Great product for beginners - us!
      Verified Purchase

      We are just beginners and wanted a telescope that was easy to use to view wildlife as well as do some watching of the night skies. This was very easy to put together with clear instructions. Appears quite sturdy too, yet light enough to easily transport.We haven't had many chances to use it yet as we have been snowed in and it has been very cold but from what we have been able to do we are most pleased with our purchase.We did a lot of research before purchasing and this product met all our needs.very easy to use for beginners and images and power of magnificationare perfect for us. The online guide to buying/selecting a telescope provided by Overstock was very useful in helping us select. Great value for money.
