Thank you all for the generous comments, Mike I think the tilt you are seeing is mis-collimation.
As soon as I did the flats I knew straight away my collimation was off, The brightest spot of the flats were not dead centre but two thirds further up the frame.
I'll have another go Friday night and maybe get 3 hours of M20 data and make sure collimation is spot on.
Thanks
Bill
