not fully pocessed


The camera is tilted quite badly left to right and therefore you may have missed focus:


Send an example of each of the frames you used if you like. If not we can only be general.

Otherwise, it's good. Maybe just make sure your flat frames are taken correctly and lose the filter?

is the tilt problem causing the larger stars on the left


If you are sure that the 5d sensor is orthogonal, loosen the m48 collar inside the adapter then with the telescope vertical and with light pressure pushing down on the rear of the camera, tighten the grub screws gradually. If not, get a m48 tilt adjuster. I think there's a dedicated one for the cat.
