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
