Using the ASI071MC. Sorry I uploaded the wrong file here is the TIF file. I took all the subs plus the calibration frames at -5c.

Thanks Colin I just tried that utility but didn't seem to have any effect. No, only dithering after each exposure. I'm using SGP and PHD2 for guiding and capturing/sequencing.
Very strange, it seems like its striped all of the colour out of the stars and galaxy then dumped it into the background in those bands.
