I normally shoot jpeg, but occ do RAW, i just find jpeg easier to manage. |
Save your single RAW or (preferrably) a stacked series of RAWs, to a 16-bit TIFF file or (preferrably) a 32-bit FITS file and you should be good to go.
You can stack multiple JPEGs if you have no other choice, but the end result will always be worse than if you were using RAWs. If you camera does not save in RAW, be prepared to stack *a lot* of JPEGs for any sort of signal that comes close to just a few RAWs, especially for the fainter stuff.
Bear in mind though that there is no condition under which just a single JPEG frame will suffice for any sort of serious processing.
Hope this helps!
