The moon is pretty bright so don't overdo the exposure time. When we saw the previous lunar eclipse in the UK I lent my tripod to a friend who had a 300mm lens and did hand hold shots with the kit lens on my D40. My
results weren't that stunning and unfortunately my friend assumed that he needed quite long exposures and didn't check back on the LCD to review results so ended up with bright blobs rather than a detailed image.
The light drops as you reach totality but don't forget the lesson of checking the results as you go along (remembering that any built in metering is likely to struggle with making the right choice unless you use spot metering on the moon itself).
