[ATM] Help needed with foucault
Hi all,
after polishing my 10" F5.6 mirror for hours and hours (still heading for a sphere), I'm currently not sure if I see a strong TDE in foucault images, or just reflections of the mirror's
edge. Maybe some of the experienced testers can have a look at the URL below, where I put four images taken at ROC, +2, +4 and +6mm (~100 KB each). What do you think? What should be the
next polishing actions? After making short strokes with little overhang there seems to be a central hill, the edge didn't change much.
