John Moore <jamoore42@yahoo.com> informed :

<<It must be very slite,, and very minimal !!>>

In my 113mm dia small mirror of 2000mm RC, I find
possibly from last 3 or 4mm the straight band takes
very very slight departure and possibly from last 1 or
2mm it takes back curve.

May I know if I don't remove this, will the image be
fudgy?

May I also know which one - TDE or TUE (at same
levels) is more damaging to sharpness of the image?

Thanks
Ajnabi
