Not worth it
Extremely disappointed. I wasn't hoping for much, but this..ugh. first off, the instructions are horrible. Take it from the person who puts together boxed furniture. Second, i can see the stars better with my phone. Third, the company said put the telescope together wrong. I was mad that the nat geo logo was upside down. Then i was mad the cap didnt fit. Turns out, that how they put it together. I was able to flip it, but i feel like thay could be why i just wasted 100 bucks on a Christmas gift. Just dont bother with this.

National Gro Telescope.
We received this after Christmas. A part was broken so I called the company but no answer. I went online to request replacement. Yesterday, I received parts that were not needed or requested. I’m thinking about returning it.

Great buy for price.
Really enjoy this telescope. I’ve been looking at the moon with my daughter (6 years old) for the past few days and the view is amazing. We both love it!
