Hello everyone,

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 :
 

No rotation

90° rotation

180° rotation

 

And with the aberration inspector script :

 

No rotation

90° rotation

180° rotation

 

Also made them avalaible to download in PNG if you want : https://www.dropbox....dNZAbvH7La?dl=0
