To take up Steve's point, you can get decent shots of the moon at prime
focus [camera body only], or with a 2x barlow. DSLRs suffer from vibrations from the mirror and the shutter. You can reduce the effects by locking the mirror up in cameras that have that feature. The best results will come from
using a high shutter speed [the exposure is over before the vibrations really get under way. I suggest 1/3200th or 1/4000th, and get the right
exposure by changing the ISO, 1600 will probably be fairly close.
