Für dieses Programm gibt es eine exzellente deutschsprachige Beschreibung und Anleitung unter:Sequator is a free software which can track stars on multiple images, align stars and stack them.
If you don't have an equatorial mount, by stacking non-blur star images in short-time exposures, the result will be almost similar to long-exposure on an equatorial mount. However, Sequator can control the exposure properly by auto-brightness or HDR-mode output, in 16-bit TIFF for further post processing. Additionally average random noises, rather than over-exposed on a physical equatorial mount.
