A Present to me..from me.

by Robert

I am very impressed with this celestron model. I did a ton of research and knew the really expensive ones were not for me. I live near a hillside area that has overlook to new york city and was amazed what I can see in the night sky even with the local light pollution in the area. Easy to use, easy to set up. I love it!

Excellent Telescope

by Eric L.

I have used a few other telescopes in the past and this one gets great images, and is one of the best based on ease of use, durability, and obviously what I get to see. For the price, you simply cannot go wrong.

Great scope, and fun to use. The eyepieces it comes with are standard, but I already went and purchased some better ones (I bought the 94303 kit for about $150).
