Welcome to Digital photography discussion!
Yes Moon dance! What do you do when you get a DSLR and you can control the exposure? Play with long exposure times! That's what I did. When I just got my XSI, I was playing around with the long exposure times. 1 sec, 2 sec, 20 secs etc. Did you see the sunset pic with 20sec? Just check it out.
By the way, when I was heading back home one day, I noticed Moon & Venus so close to each other and bright too. As soon as I reached home, pulled out my XSI, hand held it and set it for 4 sec and manually moved it to make a pattern. The result is this witch face :-)
