ok, I'm no expert at all, but I was happy with the hand held shots that I got two nights ago.
I have no idea why it worked, but I set the f stop to 8, and then I set the shutter speed at about 1/125 all the way to 1/350. I even did one at 1/450 for reasons unknown to me. I just HAVE to push the limits to see what happens. Anyway, I got some decent shots of the moon, where the craters and shading were definitely perceptible. I did it with three cameras -- I used a Canon S3 IS with a 12x zoom, plus a 1.5 X telephoto lens, a Konica Minolta Z3 with a 3x zoom, and a Samsung Pro 815 with a 15x zoom and no antishake. Oddly enough, the Samsung came out with the best pictures, probably due to my steady hand and its 8.2 megapixels.
Maybe if I used a tripod I would have got one of those cool shots with the craters so crisp and detailed almost like looking through a telescope --
which brings up the next thing --
is there an adapter that one can use to attach one's camera to a telescope and photograph it? I saw a nifty "telescope" lens for a Canon AE program on ebay that sold for around $170 or something, including shipping, but I did not even put a bid on it.
You can go to my deviantart account (in sig below) and check out the full moon shots. Those were just quick, handheld shots taken from the front porch.
You can check out the settings if you download the pics and view them in Photoshop. The data is still in the metafile.

Photoshop could not help this shot. it's too soft and dog ugly -- but damn it would be a great backround for a grade B horror movie title!
Hope this helps.
