Visited my folks for the holidays. I wanted to try my hand at shooting star trails. The first 2 nights were cloudy but I got a break on the 26th and this is the result. This image is a stack (combination - like a stack of playing cards) of 90 30-second shots. I stacked them in Photoshop (an automated script in Photoshop that places each shot into a separate layer) and then set the blending mode to Lighten for all layers. The Lighten mode allows the highlights (stars) to show through all layers combining them and creating the trails.
