Some Demosaicing routines are worse than others for noisy images and I encourage anyone to try as many as possible to see what works best.
Nebulosity, for example, uses a demosaicing algorithm that is very simple - it's exactly its simplicity that makes it a much better candidate for dealing with noisy images than the more complicated algorithms found in the various photo processing suites.

Very interesting. I'm definitely going to look at my subs and debayer with different softwares and compare the results. I wasn't aware that noise from other channels in the bayer matrix could bleed into neighbouring pixels during the process. Thanks for pointing all this out Ivo.
