Noise reduction by stacking and averaging exposures, again
I realized I had previously been doing this with camera raw color noise reduction applied to each of the frames, so I tried it with zero color noise reduction before stacking... I think that helped retain detail, but I also think I didn't fully eliminate the color noise even by stacking a ton of exposures, so maybe I'll have to try it with just a little color noise reduction before stacking.

@masklayer Are there any shifts is view in between the shots, or were they super steady on a tripod?

From what I grasped when Google was talking up their stacking techniques, they add in that slight jitter if the user's hand isn't providing it in order to get each pixel represented by each type of colour filter
