This Star Trail was done by StarStaX using the "Gap Filling". Cool thing I like about this shot is it also captured the Milky Way in it, when I saw that on the spot I was wondering what would it look like in the final processed picture after it draged over the frame after 60 minutes when I completed this session of shots, and it definitely doesn't look as "clean" as what I saw on the spot, actually looked a little "messy" here.
