Some shots I took this week-end with my Pentax *istD. Seem to have so problems bringing up the colours. Shot in raws (PEF) at ISO800/1600/3200 1min exposure through ED80 at prime focus - G11 - PHD guiding . Processed in CCD Stack. Bayer converted in one shot colour. Anyone have any idea what I might be doing wrong?

When I shoot inf TIFF colours are ok.
