RMole Posted January 18, 2022 Posted January 18, 2022 Advice sought on how to stack multiple images of stars (taken in one session) in order to create a single star trail image please. Fairly simple terms if you would as very new to this aspect Quote
NotMyFault Posted January 18, 2022 Posted January 18, 2022 Hi, just use File>New Stack. Uncheck alignment options. adjust stacking mode to get optimal result (depends on source images). You can remove the layers from the stack, and experiment with layer blend modes. May add a radial blur, center carefully positioned to center of rotation, to get a smooth trail and fill possible gaps between 2 captures. Assuming you took multiple long exposures, without long time gap between images, from tripod.

RMole Posted January 19, 2022 Author Posted January 19, 2022 Hi, I do like your displayed name. When I 1st read your reply - for which I thank you - I was on my phone and thought "what I have I done wrong now?" Anyhow, thanks again for your reply when next with a clear sky I will have a session specifically built for stacking Kind regards Bob NotMyFault 1 Quote
