Hi Amita, The moon is quite bright and even if we aren't that aware of that, pretty fast in its apparent travel across the sky. If you wanted to achieve just the moon in the picture (I guess so, with such a tele lens - although the fov of a 400mm is not that narrow for a moon shot) an exposure of 1/250 @ f/5.6 could have been a fair starting point for a bracketing (it mostly depends on the clearness of the sky etc.). I recall that someone suggested sunny 16 for the moon, but I tried it (at least I think so) and the results were a bit dark (better go out and meter...). Didn't you check the meter?
