malcircuit, Well, looks like my #astrophotography run last night was a bust. Not sure whether it was a thin layer of clouds or light pollution, but all the images are too bright to do anything with.
It might have worked last week because I was using a Ultra High Contrast filter, which I didn't use last night. That was intentional, because I wanted to see how much difference it makes. Apparently the answer is "a lot"
