Re: Nighttime and astrophotography with IR

[tom@xxxxxxxxxxxxxxxxxxxxxx (Tom Benedict)]

Not sure.  One person you can check with is Michael Covington.  I don't
know how much infrared he's done, but he's an expert on the subject of
astrophotography, and a nice guy as well.  He reads sci.astro.amateur
as well as a number of rec.photo.* groups.

At a guess I'd say gas hypering would kill HIE because of the baking phase.
I forget the exact temperature you're supposed to bake at, but it would
likely be hotter than the trunk of a car on a warm day.

An alternative you might look into is straight vacuum treatment (no
hypering gasses or baking, 'far as I know).  The speed increase isn't
as marked as with hypering, but you can see improvement on Tech Pan.
Once again, there's a section in Michael Covington's book about vacuum
treatment, so he'd be a better reference than I would.

Let us know what your tests result in.  Inquiring minds want to know! ;)
