Chris,
I don't push my E200. With a long shot, 45-60
mn, I don't think that it's really necessary. With the Super HQ I plan to
reshoot Melotte 111, reshoot Markarian's Chain, and shoot M92 with the
comet. After that I'll rewind the film and switch to E200 for the rest of
the night. This will mainly be just a test. As for hypering, I don't
own a hyper kit nore do I have any experience with hypering. I browsed the
archives and it was mentioned that hypering may not be necessary in a fast
system similar to mine with Super HQ. I would like to purchase a hyper kit
but I think I should wait until I have more experience and more consistent
results shooting. Once I have all of that, then I'll start looking into
hypering, shooting TechPan, etc. Give me another year or so at
least.

Daniel, Ill try a stack then, based on your
experience of 2 images at 45 minutes each on E200 pushed one stop. Well
see how that works out. There are some good Ha objects in the morning
sky now. I hypered the Super HQ100 for 10 -12 hours at 50c and 1 psi in
my hyper tank. Do you plan to hyper this emulsion?
Wow Chris, that's encouraging to hear, and I'm
just a newcomer to astrophotography. At Mount Pinos 45 min shots at
f/5 seems to produce a good exposure. That shot of IC 1848/1805 was 35
min very high up and the slide is dark and shows little detail. I had
to process the hell out of that thing to get nice detail. My shot
of IC443 and M35 was 35 minutes and was taken before the end of twilight so
the slide has a much brighter sky backgroud than my other, longer
shots. The longest I've gone is 45 min and the sky fog just starts to
show up. Looking at my two shots of M13, taken almost directly
overhead, the 40 min shot could've gone longer. I plan some 60 min
shots next month which might end up being a perfect length of time. I
feel a tad humble and not like I'm in a position to make many
"recommendations" but I'm planning on mostly 2-3 45-60 min image stacks this
summer and fall. I'm also playing by ear, or eye, depending on the
object. I'll trying Super HQ 100 in a couple weeks as well. My
goal this fall though is to bag the Whitchhead.

Daniel, those are beautiful and contrasty
images with excellent color. I am shooting f/5 with my newtonian,
and will shortly be using the E200 prime focus. I am very encouraged
by your work! Would you recomend one long exposure or stack two 45
minute shots?
I think I've squeezed about as much
nebulosity out of this scan of IC 1848 and IC1805 that I took last
Sept. I son't exactly like the star colors in this shot but I was
unable to change their colors and make them still look decent. I'm
posting this one on my site now, but I plan to reshoot these two later
this year using multiple shots with much longer exposures and
repost. Thoughts?
Daniel
