Hi Jim.
I gather you are trying to take a bias frame. How you do that depends on the camera. If you are using a dedicated astro CCD then the program that operates the camera should allow you to take 0 length or bias frames.
If you are using a DSLR then you will simply have to set your camera manually to its fastest possible shot (ie 1/4000 sec).
If for webcam (not sure why you'd need it) then the same applies as for DSLR, just the fastest exposure you can achieve.
