Very, very, nice for a 1st try. I do Astro Photography when I'm in Cholla, but I have never tried doing a time lapse.
That is as good as any I've seen.
He is a brave one because it was 90 degrees with 80+ humidity last night,
and took 4 hours to get all the captures for a 7 second clip.
I would have been in the car with the A/C on the whole time after setting up the camera.
