WoW! Your work is at least IMPRESSIVE Todd! Thank you! Another question: have you tried hypered Fomapan for astrophotograph? any pictures? I would also like to see the H2 hypering setup if you wish!
Yes. I posted a few results some time ago and they are on my Flickr page:
Orion Nebula/C8 SCT @f/6.5, 20min. exp.
Orion Nebula, C8 @f/10, H-alpha, 10min. exp.
These are not good shots but were more so tests from suburbia with plenty of light pollution. Out of all the testing I have done Fomapan 400 had the best response to H2 hypering along with extended red sensitivity. It's not like Techpan but it does attain a significant response to H2 treatment. It is very grainy and not a great choice for wide-field but I still intend to pursue it.
I don't have a picture of my hyper setup. It's a Lumicon large hypering chamber, vacuum oil pump, heated by a Best Value Vac hot plate that is temp regulated. I wrap a towel around it and is covered by a large styrofoam cooler. For B&W, I use pure H2 and use nitrogen for purging the chamber and soaking. I'll try to later post an image of the rig.
