Here's one from a late AM night of bouldering with Paul near Carson City, NV.
The shoot was a little disorganized, we showed up in the dark, the batteries were dead on our spotlight, I had never been to the spot before and Paul had only climbed there once. On top of that, it was ridiculously windy and the stands blew over a few times.
2x Nikon Sb-800s with CTO gels to freeze the climber (sort of), 1 LED flashlight (red gelled) to paint in the rock and background. Photoshopped out the SBs. The white balance was set to tungsen and the final exposure was 8 seconds, f/4, ISO 1000 (to pull in the stars) and the speedlights set to rear sync.
There's a bit of motion blur from his leg moving, but it's not bad.
By the way, just after this shot, the rock broke and since someone had moved the crash pad out of the shot, Paul hit pretty hard, but still landed on his feet.
