Hello! I am getting the itch to try another ATM mirror. I'm thinking of something of a challenge - a 10" f3 newtonian.

    Just curious how a Wynne corrector works with newtonians for photometry? I saw that APASS used a Wynne corrector.

    The APM/TS 2.5" Wynne corrector looks like it would do the job for what I have in mind. Best regards.
