Review: Happy with it - I managed to see a little Jupiter, it was an incredible experience, and of course you can see the moon, but I recommend to buy a lent for 4mm

### ⭐⭐⭐⭐⭐ Good beginner telescope
*by J***S on 5 February 2026*

This telescope has allowed me to get a good view of the moon and Jupiter with its Galilean moons (although it just looks like a bright dot) Pros Easy to build ✅ Good quality ✅ Good value for money ✅ Cons: It is a beginner scope so its usage is going to be limited by its aperture. Overall, I would deffo buy this as a beginner who wants to learn and start exploring the sky without breaking the bank. The dobsonian makes it easy to look through and position without having to worry about a tripod.
