Managed one more set of subs (26th) taken in clear skies, and with less moon (and farther away) than the first 32 subs ... ended up tossing the subs with the worst gradients, but had to use subs with worst seeing.
Same issues imaging this galaxy as the previous galaxy (NGC 3953) ... hazy skies, brightening moon, and periods of thin high clouds ... only the moon was brighter and nearer! Really bad gradients ...
