I think I’ve found the problem with eggy stars
It’s “tilt” in my camera
I just realised I’m using a new coma corrector and the old one had a piece of electrical tape on one side opposite the grub screws which I’ve used with the new camera and perfect stars
I was out last night imaging with new coma corrector with no tape and same issue on Carina
I’ll fit the tape on the new coma corrector and wait for the next clear night to test
Should sort the issue
Cheers
Martin
