I try to shoot the moon several stops UNDER exposed. Then I use increase contrast ONLY to bring the exposure back up. Doing this drives the background to sold black and gives more definition to the craters. If it looks good on your camera monitor, it's too bright!
I sharpen at about 1 pixel radius and 50-100% in PS elements 5, usually desaturate the color and that's about it.
I also use MANUAL exposure and MANUAL focus ONLY. I shoot about 20 shots in manual focus refocusing between EVERY shot. Out of 20 shots manually focused one will simply be better than all the others. I've never gotten what I thought was a good shot using auto focus on the moon.
Unfortunately I am at work and can't post any of my moon photos (I also probably should be on the forums either
)
