I knew it was weak, but t hadi rained all day and was forecast to be cloudy over night, so I didn't recharge it earlier in the day. As I was ready for bed, I looked out the window and beheld a full moon. Setting up the camera for some test shots of the full moon (I had researched camera setting several days before), I prepared for a long wait...until clouds rolled in, obscuring the moon once again. So I packed up the camera and went inside...only to behold out my window the moon, already partially in shadow, Out I went to set up once again, as the sky got hazy and ground fog began to develop. This time I waited it out and while the sky was not as clear as I would have liked, I did get to watch the eclipse, snapping multiple exposures. Just as the moon was emerging from the earth's umbra, and things looked like they were peaking...the battery died.
