A side effect is problems with ghosting after-images from bright stars in the focus shot. We don't want to flush the sensor between shots, because that measurably increases noise, and we're more interested in catching faint stuff than we are in getting rid of these blobs of ectoplasmic slime (don't cross the beams). If we did more colour subs, statistical outlier rejection should get on top of them.
Glad to see you're looking so closely! 
Best,

I got kinda lost in all those tincy wincy galaxies, hundreds and thousands of them! Gotta be difficult getting rid of every little reflection ect in those bigger systems
