Digital Camera World Verdict

StarStaX is great for creating star trail astrophotographs to make several still images look like a single, long exposure. But it’s also useful for reducing image noise by compositing together dark frames, and can be used to enhance relative exposure in dark images by stacking them together. Fast and easy to use, it’s free and available on both Mac and Windows operating systems.
