Yep, I see that thanks, H. I understand there is some debate about the value of separate bias frames. I haven't formed my own opinion yet. Maybe once I've finished reading the Handbook of Astronomical Image Processing...

Just to add a slight on-topic note: the Image Trends Fisheye-Hemi plugins do a good job of correcting fisheye distortion (IMHO).
