We vacation almost every year in Brant Lake, New York. I've made a habit or a tradition out of doing a star trail photo at our camp every year. The Adirondack's have some of the best dark skies on the east coast. I was only able to use a little over 200 photos for this as clouds started to roll in and ruin everything.
This actually came out better than I expected. I wasn't sure I was going to have enough photos for decent star trails because of the clouds. I blended in the star trail photo into a blue hour photo, shot for the foreground at f/8 instead of f/2.8 and to mitigate some of the ambient lights coming from around the lake.
