Wow! Got two of 16mm for binoviewing with Baader MaxBright II in a Takahashi FOA-60Q. This scope is perfectly matched in the longer configuration f/15, and excellent also in f/8.8 mode. It does not matter that the field is so wide I can’t see the field stops when in binoviewer; I look through and just see the sky, perfectly clear! They are my new favourite eyepieces in this scope. I await good enough night to use mono and bino in my Celestron SCT 11″ EdgeHD.
Astro Hutech service was excellent too. 🙂
