HI Trev, no I don't use the in camera noise reduction -would make the subs even longer!
I just tried to post process (Star tools) it out but because the sensor temp is so high if you stretch it more you get horrible read noise every where.
Looking around for a CCD again now. Have an old style QHY which has the older style cooler control on it- I took a series with that camera and an 110mm refractor which I will put up to compare.
