I recently started shooting star time-lapses out of my kitchen window. Being near the city, I thought that we would have too much light pollution, but they actually look pretty good if shot correctly.
Then I thought, could I use these time-lapses for star trail photos? And could this be done easily and cheaply?
The short answer is yes and yes with StarTraX.
30sec exposure at 2min intervals for 9hrs (1.5min gaps):
25sec exposure at 30sec intervals for 3hrs (5sec gaps):
Settings were Gap filling + Comet mode (default length).
If you sharpen and brighten the images prior to processing, you can get more trails.
So much fun!
Closer intervals are definitely smoother. Next, I’ll have to try this with no gaps (except shutter and file saving).
