I agree with Leo. I did extensive film photography, had my own darkroom, and including some astrophotography.

The hardest part was trying to get sharp focus. Liveview makes this so much easier. But I understood the media film as slides or negs and printing paper responses and I could always pre-visualise how the image would come out.

Back in the 80's, Kodak TP 2415 had a very low ISO but was one of the few films that was red sensitive. I believe it is no longer produced. Current offerings don't have much red sensitivity, or didn't when I used them for AP 30-40 years ago.

SteveinNZ2 listed some. I have never used Fuji Achros. HP5 is ok for stars and blue reflection nebulosity but records almost nothing of a Ha emission nebula.

Frankly, having done both I cannot understand why for AP, anyone would want to blindfold themself and tie both hands behind their back?
