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.
