Great news.
For the OAG, I'm sure you are but please make it robust and free of play. I've had several 'cheapies' and they are terrible. We are dealing with such fine tolerances that even unseen movement is an issue. Also at f/3 it would be good to have a wide opening, though I don't always use telescopes that fast.
I'm up for beta testing if you're short of numbers.
Many thanks
Robert
