Hey mate,
When I used to DSLR image (and, every now and then, still do), my captured data was as follows:
lights (as many as possible);
darks (usually about 16 or 25; with a third taken before I begin, a third during the middle, and a third after I finish -- this captures the range of temperature spread throughout the session and makes for a decent master dark);
flat lights (between 16 or 25); and,
flat darks (between 16 or 25).
No bias frames to speak of, as my understanding was that the bias was always included in the dark.
The flat frames are typically in the order of 1/30th to 1 second. I might have to take some bias frames the next time I do some DSLR imaging and then process the data with and without bias frames to see what the final output image (before Photoshop) looks like, noise- and calibration-wise.
Cheers.
