This is a stack of 61 exposures, with each individual exposure being for 60 seconds.
The total star trail time was just over an hour. The last image in the stack was with

I created an animation of the star trails above. This 25s video represents the same
time period as above (an hour's worth of actual star motion), looped three times:
