Does anybody know anything about developing astro photographs on techpan 120 format film that has been hypered from lumicon. I believe it calls for d19.

I used to use hypersensitized Tech Pan for photomicrography when I was in grad school. We hypered it in nitrogen/hydrogen gas mixture which I think is how the Lumicon stuff is hypered. We developed in D19 for (I believe) 4 to 5 minutes. Generates a really contrasty negative.
