Mt Chocorua is one of the very few accessible mountains in NH which has a lake right in front for its reflection to be visible. The night was very calm and the water was still. I waited for the comet to align with the top of the mountain. I kept my shots on from 9:00 PM - 11:00 PM. This shot is a stack of 8 shots taken at 10:50 PM when the comet aligned perfectly.
