If your digital camera has a video-out socket you can connect your
camera to a mini-TV. I used this method on the Venus transit using a
tiny 5" B&W TV from the supermarket. (~=A310]. The bigger screen
enlarges the image enough to read the exposure details which are
usually quite invisible on the usual LCD screen. I used this feature to
capture snaps of the transit using the fastest exposure figures in
rapidly-changing cloud cover. Naturally the larger screen allows much
more accurate focussing. Those with a weatherproof observatory can use
a larger LCD screen. It should be a very dry night (or day) to use a
conventional TV out of doors. A domestic TV and condensation are best
avoided. Downside is the bright TV screen affecting your nght vision.
Though with the moon as your subject this is unlikely to be a serious
problem.
