Hi all,
I'm trying to work out why I may have excessive field curvature (60-100% as measured by ccd inspector) in my photos from my 8" lx90 ACF f/10 and QSI 683WGS combination, but firstly, what have others measured from their set-ups using a Meade ACF f/10? I'm not sure what I should be expecting.
I noticed it why collecting subs for this
image. The image has been cropped a little, but you can still see it.
I have also posted the same question in the lx90 yahoo user group.
Thanks,
Aaron
