Sequator

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.

Easy; user friendly Fast Automatic determination for best parameters Capable under heavy light pollution Powerful correction for wide-angle & complex distortions Intelligent sky mask Foreground detection & stacking Star light enhancement function Light pollution reduction function Support star trails mode Batch processing for time-lapse Support RAW & 16-bit TIFF

Sequator will not provide too many confusing options; in contrast, strictly select the most effective features for you. Endeavor to automatically determine best parameters, save the time from boring trials. "Simple but powerful", is the core philosophy of Sequator.
