Flats and Darks for wide field imaging?

Hi all,

"Flats and Darks for wide field imaging?"

Right now, I'm using a DSLR camera on an EQ mount to take widefield exposures. I take a number of 20-30 sec exps at ISO200 or 400 and stack in Registax to produce a final image.
My question is, would these images benefit from either Dark and Flat field subtraction with Registax, or perhaps just Dark field subtraction only???
Cheers
Doug
