I am learning to use APP and also downloaded the astroflats plug in for PS that someone mentioned on here. APP stacked more of my unmodded DSLR pics but then didn't tell me how many more it used !! all I know this is more than four hours ISO 400 at 300sec Samyang 135mm unmodded Canon 6D.
Stacked in APP and star colour calibrated.
Then PS 5 for the rest.
Hope it pops a bit better.
