This might sound dumb but how do you normalise the raw frames
I would assume in a program such as Canon Digital Photo Professional you would apply the same levels historgram balance etc to all the subs

I do all normalisation in CCD Stack. Normalisation is important to do data rejection prior to stacking. That's how you'll define hot pixel, outliers, etc... It will not get rid of gradients or difference in luminosity. Scaling, DDP and blending operations have to be done manually unfotunately. I don't know of any program who does automatic gradient removal or accurate automated masking. Doing a Sum sometime works better than doing a Mean stacking when differences exist in Luminosity and the frames don't match with evident seams.
