As for the stack.
Flats are "divided" into the light frames not stacked or added in. If you have just stacked them all together you will get a horrible image as you describe.

Hi Terry, The Masterflat was added as a Flat and Lights accordingly, is this what you mean?

Then divide the master flat into your sub and you'll get the result you're after.

Thanks Marc, The flats were captured at -15deg and duration was 0.13 sec, does this sound right?

Thanks Lewis, this makes me feel I'm on the right track.
