Quoting StrangerThanYou:
I gave you a low  vote on this photo because your subject was out of focus.


That was as in focus as the lens could get, and I tried both sides of that focus point only to have it further degrade. Most of the fuzziness is owing to the fact that there's clouds/fog clinging to the ridge top and partially covering the moon's face. Some may also be due to bringing a lens that was above freezing temperatures out into 4F.

Edit: The other thing I realized is the long exposure problem. This was a 6 second shot at 208mm, f/6.3, ISO 400. I could have cranked up the ISO, but it was as wide open as possible at that focal length. A tracking mount wouldn't help this shot because it would blur the landscape. I think an ISO 800 shot at 3 seconds would have been crisper. I played around and have a few other variants of this one which aren't quite as good. I definitely wanted more definition in the earthshine part of the moon.

Thanks everyone! I had to get up pretty early and endure some cold to get that and I think it was worth it.
