It seems to me your collimation is not good. The stars in the differents corners seems to be defocalised and deformed. I think you have coma indicating your primary miror is not correctly set. I did the tilt tools with Astap and look  and the abberation inspector shows your star not good in the corners  Maybe you should fine tune the collimation of the primary 1st. |
