Thanks Mark , Theo,

I think I've removed most of the off axis tilt tonight because the
focus seems a lot crisper.
The only misalignment now might only be collimation, seen here
with this crop of NGC2822 and Miaplacidus.

Edit: Eta Carina from tonight added too.

Mia was almost centre to the FOV so the ghost shows the extent of the
collimation.
I'm glad that blooming type artifact is gone too.
This camera is a bloody beauty. The dynamic range is lovely under a
big light bucket. This is just a 10s shot series and stars have saturated.

Steve
