Re: [ATM] it's finished

Hello Ken,

Thanks for your comments. My mirror is 8" F/6.55 . For
now I don't know that what is the total correction.
Only compare with pictures that is illustrated by
RonciZ program. I will get star test asap. But, I know
that I should make a foucault tester.

Best regards,

Lutfu
