[APML] TechPan Hypering with high vacuum

[* <astrobound@yahoo.com>]

I'm sure this is an old can of worms but... Where are
the best links for "personal best techniques" for
hypering Techpan in 120? I have a Lumicon 600 setup
with both temp probes and a high vacuum pump. I've
heard that the later emulsion can be hypered in the
paper backing without the Kodak Nebula problem. If
possible I would like to remove the backing after
hypering for use with a vacuum back camera. My main
interest is with the use of the high vacuum pump and
how many cycles are needed to dry the film before
hypering? I've also heard Nitrogen instead of forming
gas can be used for the prehyper vacuum treatment?
