baader MPCC

[bmitchell82]

hey can anybody name the actuall corrected circle and illumination circle of the baader mpcc, i can find metal back distances and what not but nothing else.

I have used the MPCC with a SN10 and the Canon 5DH and it vignettes at the corners. For a C size sensor it should be fine with very little vignetting or distortion.

I will see if I can dig up an image and or a flat.
