Hi Greg,
I think this shows the difference:
Attached color image is the fully calibrated LRGB composite I started with for the Arp 244 image (no flocking). The rainbow is caused by an 5.3 mag star (SAO 157042) 50' away from the galaxies. Subs here were 15 minutes each.
Attached mono image is after the flocking: Altair (mag 0.76) is right on the edge of the chip, ~18' off axis, 60 sec exposure, bias and dark calibrated, stretched using high setting in Maxim.
I've attempted to adjust the stretch to be about the same for similar brightness stars, I think.
