This was shot on a July, 2010 trip to Zion National Park in Utah. My friends and I took a short night hike on the Par'us Trail and stopped so I could do some astrophotography. The moon was setting opposite the direction of this shot and provided light for the mountains. The light on the foreground trees came from cars passing on a nearby road. I was shooting so long that my poor friends fell asleep on the paved trail. (They were pretty tired to begin with.)
And yes, that is a shooting star in the middle of the photo, one of the brightest I've seen. I couldn't believe my luck standing there with the shutter open.
The Milky Way is absolutely incredible from this location. On a prior night hiking the Par'us Trail my friend thought, for a moment, that the Milky Way was a group of clouds lit by artificial lights. That's how clear and bright it was. Ever since that summer I have dreamed of going back to Zion and photographing the canyon from a higher trail with just the right combination of moonlight and darkness, and the Milky Way in all its glory.
This is a single exposure, but the land and sky were masked and processed differently. I don't recall the exact exposure time, but I was shooting 1-3 minute exposures at ISO 1600 and f/2.8 using my 7D and trusty Tokina 11-16. I was using Canon's remote timer release to time the long exposures. (Edit: huskyte77 discovered that the time was 45s. I didn't realize the time was recorded in the EXIF, just under a different tag in bulb mode.)
Work has kept me away from posting to Flickr for a few months, but I'm going to try and post an image a day and comment on my contact's photos again.
