Ray, why would you want/need to temperature match the flats?

Re: Noise, one can also do Gaussian pixel blurring to smooth out flat noise (but still retain sufficient definition of dust motes). I generally take 100 flats per filter/session to minimise noise, which is possible when using a light box.
