Daryl – There are certainly a lot more trails on my images this summer compared to previous years. For imagers the way that you stack subframes can help to a certain extent. The animated GIF attached is the same frame stacked as average and as sigma clip. There are 5 satellite trails on this image, two bright ones and three faint. The sigma clip stack definitely suppresses the bright ones. Photometrically the two stacks are the same.
