Celestial Photography at Arches!

Just returned from 10 day biking/hiking trip to Steamboat Co.  Had the opportunity to do a great side trip to Arches National Park (outside of Moab Utah) and grab some great shots of the spectacular/iconic rock formations against the backdrop of the Milkyway Galaxy! I started shooting about 10:30pm when twilight had receded and the night sky was in full bloom.  For you tech-heads out there….here’s how I grabbed these images: I used a full frame SLR with a very fast fixed focal length lens (Canon 6d and Rokinon 16mm f 2.8). The Camera was mounted on a tripod, with the lens held open for approx 25 seconds (F2.8 @ 2000 ISO).  Long enough to get a proper exposure, short enough to avoid star trails.  Ie. the stars rotate around the North Stars….if you leave the lens open too long…you get streaks. I illuminated the rock formations using two techniques.  A.  I started using LCD flashlight with colored gels…to bring out the natural color of the rock.  I typically positioned the camera in front of the arch, then painted the arch with light from the side.  I trigged the camera using a remote blue-tooth shutter release.  B.  When the moon came out later in the evening, I used that as the additional light source.         Share...
