Star Trails at Double Arch
This is the first "star trail" image I have shot, and shot, and shot, and.... Actually, this image is composed of 480 exposures made over a period of two hours and eight minutes. That's one exposure every 16 seconds. Then, the magic of StarStax software took over and combined those 426 exposures to produce the final image seen here. A couple of items of interest: the colors you see are natural - different stars produce different wave lengths of light and different wave lengths produce different colors. So - natural. Second, because of the lengthy exposure time I captured several aircraft and satellites passing through the image. Those were eliminated by deleting the files in which they appeared - PIA but necessary. Finally, the site of the image was beneath Double Arch in Arches National Park, Utah. And, what did I do for the two plus hours the camera was working away? I actually took a nap on the rocks - not comfortable but when you're tired and bored you can do it.
