Armed only with boxed wine, firewood, and our DSLRs, we had to conquer epic climbs, sand roads with the 4x4 Jeep, and the occasional UFO... But it was all worth it when the skies cleared and showed us an incredible galactic palette! Star Trails shot at 25 sec exposures. No special effects used, just the rotation of the earth's axis. Photography Merging: STARSTAX. Used Canon 5D & 7D, with a 24mm/1.4 lens and a 28mm/1.8.
The Geminids get crazy as the sun comes up (2:20-2:35) but you can spot a bunch more throughout, if you look closely.
There's also some passing planets (1:15-1:30 and 2:15-2:25). I think these are Jupiter and Mars(?), but maybe some smart astronomer out there can verify?
The "UFO" appears at (1:30-1:35) and makes three broad circular sweeps over the desert. Though in timelapse it appears to be moving fast, consider the 5 seconds = about 50 minutes, so it's creeping. There was no sound, so it definitely wasn't a helicopter.
Remember this is in timelapse, so it would be moving EXTREMELY slowly -- too slow for a plane. And no sounds from a helicopter or any other kind of craft were heard
Originally posted by ChadwickusI watched in full screen and caught something pass in front of the dunes at the 1:30 mark, moving at a similar speed to the object in the sky.
Same object or not I'm not sure.
color emphasis mine

If you have astronomical imaging of the sky with celestial coordinates you do not know—or do not trust—then Astrometry.net is for you. Input an image and we'll give you back astrometric calibration meta-data, plus lists of known objects falling inside the field of view.
We have built this astrometric calibration service to create correct, standards-compliant astrometric meta-data for every useful astronomical image ever taken, past and future, in any state of archival disarray. We hope this will help organize, annotate and make searchable all the world's astronomical information.
I only ask about the time frame involved because the lights ARE so typical of aircraft aviation lights -- steady red light on left side, steady green light on right side, and a blinking white light. The lights look so much like the lights on a plane or helicopter that I wonder if the assumption of 1 second = 10 minutes could be a wrong assumption (even though that's what the article said).
EDIT TO ADD:
By the way, the idea that each frame in the video is a 25 second exposure fits in nicely with the idea that the blinking white light in the long exposure still image is an aviation collision avoidance light. Collision avoidance lights are suppose to strobe at a frequency of between 40 to 100 per minute. I counted the white dots on that still image, and got 19 "blinks". If we consider that image to be a 25 second exposure, then the frequency of that light is about 46 blinks per minute -- which is consistent with an aviation collision avoidance light.
