I am a rank amateur compared to yourself Greg, but what I USED to do:
CCDStack:
1. Open each filter as a set.
2. apply Dark/Bias/Flat
3. Register, usually using auto, then applying Lanzcos/sinc 36.
4. Do a mean or Median combine - see which one had a better balance of noise reduction and detail.
After each filter set is done, then load up the Mean or Median combined of each filter, reregister, apply normalisation (I think I used the Lum file usually as the base), then run rejection and interpolation of rejected pixels, and use the LRGB combine. Then I will usually do a background neutralisation, and then fiddle a LITTLE with the image tools with DPP and the others to try to stretch it a LITTLE. Save as a TIFF, and into PS CS6 or 5.1.
In PS, I usually used to run vibrancy and saturation first, followed by either a small stretch or run my detail extraction algorithm.. then fiddle somewhat with light noise reduction (maybe a small median blur), some contrast enhancement with overlay and screen masks, and voila - Lewis's Cruddy Low Data Integration Images
