St. Olaf Stars: The Story Behind the Photo

St. Olaf Stars by Bill Webb

This star trails image is a composite of 125 images taken using an intervalometer to trigger the camera every 16 seconds. The individual image exposures were 15 seconds long at f/2.8, ISO 1600, using a 14mm ultra-wide-angle lens. I positioned my camera to place the polar (North) star above the steeple.

Capturing the photos took about 30 minutes. In Photoshop I stacked the images to create the trails.

The light on the cemetery markers is caused by another photographer who turned on his car lights (a REAL no-no) while I was doing this. I have another version of this image that eliminated the lights (they were on for just two frames), but I kinda liked this one.

The location is St. Olaf Kirke (The Old Rock Church) in Cranfills Gap, Texas. Gates into the property are locked so you can’t just drive in.
