Question NGC 6188 Tak FSQ106ED & QHY8

This was a problematic image for me, but it was all my own fault!!

The image was to be a ripper consisting of 15 X 20 minute images but alas I didn't check my focus during the imaging session and with the temprature dropping from around 13 degrees to 3 degrees in a couple of hours my focus drift was quite large.
Anyone who knows these scopes will be aware of the small critical focus position and how a small change can totally stuff an image.

I ended up with 5 X 20 minute exposures I could use.

The image was cropped a little to get rid of some Ice which formed on tthe bottom of the CCD due to the low tempratures. Camera was somewhere around -40 degrees C.
