Startrails over Yosemite Valley

My first attempt of a startrail. Got this dashed line instead of a straight line because of a 30s gap between shots. You can see a few airplanes crossing the sky and the lights of some cars driving by the valley on the lower right.

 

There were only two photographers left at Tunnel View after twilight when the other guy told me he was gonna try to do a startrail, so I followed him until I run out my last battery. Had I more spare batteries, I would have waited for the Milky Way. Maybe next time...

 

I used my old manual focus Pentax M 50mm f.17 for its wide aperture and infinity focus.
