My first attempt at longer startrails - good low-noise results (with some exceptions) but a boring composition.
Now I'm going to have to drive down that damned washboard road again to do it right. What I wish I had was a 30 second twilight exposure that would have lit up the playa and Grandstand. That actually was my intention, just didn't get there at the right time.
25 - 5 minute exposures
stacked with www.startrails.de/html/software.html If there's one thing that I really appreciate about that program it's that there's a distinct lack of "gaps", or dim areas in the trails that I commonly see with other stacking methods.
A very little bit of noise cleanup
Simple lighting adjustments
