I went up to what is becoming my favorite lake to watch for the aurora borealis. I knew there was only a few hours of darkness before the moon would rise and I thought it would be time to head home once the moon came up. I was wrong about going home when the moon rose and my favorite photo of the night was a mistake. I forgot to tighten the ball head once and loved what happened. I tried to duplicate the effect on purpose but the original mistake was the best.
