Re: [ATM] it's finished

It looks very nice! What is the total correction if you zero on the center zone and then measure the distance to where the edge zone zero's out? That distance should be the one that will tell you if you are finished or not. OR... you can mount it ina  tube and test on a star to see if it is fully corrected. My guess is that it will give you very nice views but now that you know how to do it, you will eventually make it better!

Hello all,

After my mirror had back to sphere I started
parabolizing. 

At first I worked one session (15 min.) normal W MOT
maybe a little bit wider 1/3 - 1/2 the end of this
session result of test picure as;

It seems there is tde on the edge.

Then I worked two sessions mixing strokes;
5 minutes short stroke COC 1/4D - 1/5D MOT,
5 minutes normal W 1/3 MOT
5 minutes narrow W 1/4 MOT

I think my mirror is finished. Here is ronchi;

Well, I think surface of mirror is a little bit rough.
At the end of working I tried red rouge for 10 minutes
but it didn't change anything of surface. I don't like
rouge.

At first Jerry and all of you, thanks a lot for your
helping and comments.

Best regards,

Lutfu
