[ATM] TDE on a 6f6 mirror
Good morning all,
On my initial try at figuring my 6f6 mirror I managed to dig a pretty
deep hole. So as I've had time, I've been working the surface back to
sphere. On my way back to sphere, I came to a point where all the
zones were actually correct for a parabola. The edge did not look
perfect but I figured I'd take a picture to collect the groups
opinions.
Well, I captured some pictures. In the pictures the edge looks really
bad. So here is the first picture at zone 3.

Some questions:
1) Am I correct in thinking this looks like a badly turned down edge?
2) If yes to 1: It doesn't look that bad when I look without the
camera. Should I believe my eye or the camera?
Lastly, I took a second picture with a little bit of light behind me.
In this second picture you can faintly see through the mirror.

3) Is it possible that the bright left side of the mirror is actually
a faint reflect from the inside side of the mirror blank? hehehe...
it's worth a shot... 8-)
Thanks,
