#12 Tri-X
I haven’t thought of that for decades. I use to develop the B&W film for astrophotography at home. Now you just point a digital camera at the night sky and get far better images in 30 seconds let alone several minutes with just a camera.

Long ago I traded my darkroom for an IMSAI 8080.
And like many other toys I have had, I should have kept it.
Unfortunately, I still have a cabinet full of 35mm and medium format stuff, I never use.
