This is my 4th timelapse video and my first at night.
You're looking at the Milky Way as it makes it's nightly trek across over Gunsight Mountain at Anthony Lakes, Oregon.
This is a compilation of 396 images shot in RAW. I have to say that I'm glad I used RAW to get the better detail, but dang.... waiting for over 2 hours while LR batch processed the images was crazy. While taking the photos, I had to change my CF card 3 times ended up with over 13 gigabytes. So in total, you're looking at about three and a half hours that's now compressed into less time than it took to take just one of those original photos.
Unfortunately I set up for this about 15 minutes later than I had planned. I had wanted to start long enough before full dark that the last light of the setting sun would fully expose the landscape with the 6400 ISO. As it was there was just enough light to give me that nice deep blue twilight, but still really dark. Oh well. Then the timelapse continues until the rising crescent moon was well off the horizon.
396 shots, all shot at :30 seconds, 17mm, f/4.0, 6400 ISO
First shot: 10:17pm
Last shot: 1:51am
