Good for the price
02 February 2023  | 

Have only tried this eyepiece for one evening but have been pleased with the quality for the price. This purchase was a bit of a gamble, as I have paired it with my Celestron StarSense Explorer 10" Dob and I was concerned that I would be pushing the useable limit of the scope (particularly using it in an urban area) at a 400x magnification and f/4.7. But I have been able to just about make it work with a careful touch on the focuser. But you do need calm and dark skies to get a clear image, though, with that sort of set up.

Overall, a very happy purchase and the service from FLO was great as always.
