Star Trails at Double Arch
This was my first attempt at star trails. Instead of a one-hour exposure (noise?) I set the SS to 30secs, the mode to continuous, and locked the cable release and let it keep making 30 second exposures for one hour. The arch was painted with a flashlight for 30 seconds. f/4 ISO 400. I post-processed with software (Startrails stacking program). So, Roman, how did I do?
