Here's a slower one.

1st one was 15 fps, this one 7fps, so not as smooth. I was inspired by naskies Leyburn timelapse. Mine is a bit grainy, settings were Canon 700D, 18-55mm at 18mm, f/4.5, ISO 1600, 20 sec. I probably should have gone to 3200 or 6400, and opened the f stop more. I had to increase the exposure post processing the bring out the Milky Way, but that brought in the grain. I'll have to try again sometime.
