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 226 exposures made over a period of two+ hours. That's one exposure every 30 seconds. Then, the magic of StarStax software took over and combined those 266 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.
