Hi Peter,
You are now in expert hands

. I remember now - I had to multiply my scope's fl by 1.5 (at Barry's suggestion) to get realistic mags. But there was no mention of exit pupil size, so there has apparently been some progress since then (about 2 weeks ago). The following is one of my ep entries in module.ini. Note that sfl is up to 2250 (for a 1500mm scope). Perhaps its this "correction" which is now reflected in the exit pupil entry???

name = Baader Hyperion 21
afov = 68
efl = 21
sfl = 2250
flip = h
However, I'll await the release of the fully tested 0.10.3 version before I do anything further.
