I think I spotted a bit of CA on my new TS-CF90.
Am I mistaken or correct? Does this happen for yous too?

My camera is a 2600MC. Distance to sensor is 17.5mm with a 16.5mm adapter and 21mm filter drawer.

Focus is a bit ahead of the 36mm mark.
Tilt might still be from my old telescope since I had to adapt the tilt plate to fix the tilt issue.

Will redo next time I'm out x)

Do you think it's a tilt issue, backspacing or focusing? Or maybe any others tips? 
Thanks a lot for the answers guys!
