( 5 / 5 )
I got one for my 130mm Newtonian. It was on sale so for the price I think it's good.
Using it is a bit tricky if you have no experience but I recommend that you start with the simplest guide you can find, and just check for a few times. Only after understanding all reflections should you start adjusting stuff.
If reflections are still a problem then you should use the paper in the tube trick. This helps with aligning the secondary mirror, which in my opinion is the most difficult.
I use it and get great results
