Tall formations in Alabama Hills seem to be sky gazing. This image was created using the "Stacking Method" for creating star trails, and in particular using the program "Advanced Stacker PLUS".
The original images were taken during the Alabama Hills Workshop in 2011. The workshop wasn't held in 2013, but will be held again in the Summer of 2014.
Each exposure was 236 seconds, ISO 250, f/5, at 16mm. There are some artifacts created from several causes. During the initial exposures where the rock formation was light painted the tripod was bumped so I had to manually align two images. The reason I had to manually align images was because one of the best light painting jobs blew out details on the middle formation. Subsequent painting included some bizarre colors and green laser graffiti so picking and choosing pieces from the light painting worked well (much like described in this video: NP150: Fixing Night Shot Problems).
