Hi Wouter,

no problem, I appreciate all the help that I can get. The next step will be to increase my knowledge as moving from a DSLR to a DSO imaging camera is not so straight forward as I had hoped.

Amongst other things I was struggling to get the focus correct when taking these pictures. Back to the drawing board on this one, and be more careful with the Bahtinov mask.
The elongated stars mean that I should check the Polar alignment and the tracking.

When you say "the direction of the major axes varies over the field of view suggesting rotation of the imaging camera" what exactly does this mean? As I am using an EQ6-R Pro mount there should not be any rotation so is this something to do with the telescope collimation?

I have been going crazy for the past week so can only say again that I appreciate the help and the feedback.

Best regards,
Duncan
