A gift for my young grand niece

She was very excited to receive it, and a bit overwhelmed! I’m sure her parents will help her use it and she will be very happy, since she has a new interest in looking at the stars.

Wonderful first experience

This was a perfect gift for my grandson (4) and his father. Together they have been exploring,, and took some — to us — perfectly wonderful picture of the moon. They are both enthusiastic. The telescope is simple enough that my grandson can really take part, although of course he still benefits from his father’s guidance. First steps are so important, and this telescope is truly accessible for the first timer. I’d like to thank OPT for their extra efforts to get it here for Christmas.

Christmas gift

The telescope was on order, and I was concerned it wouldn’t be delivered in time for Christmas. I did get it before Christmas. My grandson was excited and told his mom he rated it five stars.

Celestron beginners telescope

I bought this for my grandson for his birthday which is not for several weeks from now. He loves science and I expect he will love exploring the sky. Item came well packed and sooner than I expected with the pandemic I pleased with the service. I am awaiting a telescope for myself and my grandson and I can share some new adventures together across the miles
