Ive been wanting to try this since day one of getting my camera. Today I finally did. After a lot of fumbling around and getting everything set up, it turned out to be relatively simple. I just pointed it to the sky and let it go to work while I played in the front yard with the kids. After about 50 shots or so my youngest decided he wanted to use the tripod as monkey bars. Hints the random shaking toward the end of the video. It was dark and they were tired, end of experiment one. I cant wait to try it again. Perhaps I’ll clean my mirror this time and get rid of the dust particles on the images!
