Yeah, I don't even shoot f/11 in daytime, let alone night! :D

About f/8 is the "sweet spot" for clarity and wider DOF, but if you just want to focus "at infinity" for the horizon and stuff in the sky, just open it up to whatever's the maximum aperture on the lens, whether f/4, f/2.8, f/1.2, whatever you've got.

I've got a 50mm @ f/1.2 lens I like for nighttime shots, even though I'll close it up to f/1.4 or 1.8 or so for a cleaner image. 50mm @ f/1.4 lenses tend to be a lot cheaper (like half the price of a 1.2), and that's not all that much difference, especially if you close up the lens a little from wide-open.

Anyway, f/2 vs f/11 is 9 stops' worth (512×!!!), so a 6min shot ends up being, what?, about ½sec? :D

I saw pretty good ones on Aug 16, what a surprise that was! Just barely dark enough to photograph!

I didn't see anything this night, I think we were cloudy. But you got it Nancy!

Hopefully we'll have lots of opportunity to practice this winter, eh?
