StarMax is an easy Star Trails creator. Shortly, How to make a Star Trails Picture:
- Put your camera with a wide angle lens on a tripod.
- Take a lot of pictures at regular intervals (eg. 30s exposure, 10s for saving to memory, 30s exposure...) at about 400ISO and F/D=8 or more.
- Start a list in Starmax by selecting your pictures.
- Build Star Trails with StarMax-AddMax function.
- Use StarMax-AddMin process and build a pseudo dark picture that you will subtract to your AddMAx result to correct most of the light pollution.
- StarMax allows you to save each step of the star trails process, then it's fun to make an animated star trails file with a free program like VirtualDub.
