Firstly, here is my setup :
TS 80/480 with 2" corrector
OAG from Skymeca
Canon EOS 500D
Here is my problem.
I'm trying to determine if my tilt problem comes from my camera or from my refractor (or focuser).
I've measured my backfocus, which should be 123mm, with a digital caliper and obtained 122.74mm. So I don't think I have a backfocus issue.
So, I've taken three frames and rotated the camera of 90° and then 180°.
Uploaded them on Imgur :
And with the aberration inspector script :
Also made them avalaible to download in PNG if you want : https://www.dropbox....dNZAbvH7La?dl=0
