Dave_W what time of the night... errr morning?
Getting ready to head to Yellowstone on Wednesday-Sunday and should have plenty of dark night once that darn moon goes down.
This was taken around 2 AM in the morning but that was a new moon evening. Tonight the moon doesn't set until 1:37 AM so you've only a few days before the window is closed. Do you have and use "The Photographer's Ephemeris"? I think the TPE and google street view are the two best programs for photographers ever made. I live by these two.
