Colter Bay, Grand Teton National Park
Braving the dark shores of Jackson Lake at nearly midnight paid off with this 20 minute exposure. The moon was low in the northeast sky, and that helped illuminate the mountains and foreground without washing out the stars. The afterglow from the sunset wasn't visible with the naked eye and was a delightful surprise.
Some tweaks to brightness and contrast, as well as a noise reduction filter.
