I took this picture last month at nautical twilight while the Moon and Saturn rose over the arch. Saturn was amazingly bright. The ambient light from the moon helped light the scene. I set up around 3am and took numerous test exposures to be ready. I always believe in getting to photography subjects early. It comes from missing shots in the past. There's nothing like spending money and traveling extensive distances just to be a minute late while flailing around with a tripod, camera, cable, flash light, remote, and filters. I knew the moon was waning so I planned my attack. I knew It would offer enough ambient light all the way to the La Salles, and, at the same time, it wouldn't be so bright that I couldn't get stars in the picture. The snow from the day before helped accent the light on the mountain tops. I still needed fill light for the arch so I brought a flash light and some gels for the job.
