Photographer Mike Christy couldn't resist finding a good spot to photograph the "supermoon" rising over the Rincon Mountains, east of Tucson. His vantage point was Gates Pass. The photo was taken shortly before 8 p.m. Sunday.

Supermoon is an unofficial term that describes the point at which the moon is closest to Earth (perigee) for this month and year. In this case, it's about 221,824 miles away, which occurred early Sunday morning. – Rick Wiley

Mike Christy writes about the photo:

"Hiking around the peaks near Gates Pass at dusk afforded my posse and I a decent view looking back east over the city while we waited for the lunar giant to rise over the Rincon Mountains. We’d brought several lenses with varying focal lengths (from 16mm up to 500mm) and a tripod or two. I had planned to shoot my main image, the one above, with a Canon EOS 1D Mark IV on a tripod-mounted Canon 500mm f/4 IS lens.

From a technical standpoint, there were a few challenges to capture it. The natural light across our landscape was diminishing with the setting sun, calling for shorter shutter times, higher ISO speeds and wider apertures. My priority was freezing the image – motion blur (induced by myself, the wind or the path of the moon itself) wouldn’t do. I slowed my shutter speed down to 1/60th of a second. That required a higher-than-I-should-like ISO 2500 speed with and a relatively shallow f/4. I knew 2500 was going to garner a good bit of grainy noise in my picture, so I opted to shoot in RAW. That afforded me some room to work the picture in editing software and help alleviate the digital grain.

With the lens mounted on a tripod, my gear was steadied as best it could be. To play it even safer, I triggered my camera shutter remotely using a wired controller that plugs into the side of the camera."
