How AI describes Sequator

Sequator is a free software that tracks stars across multiple images, aligns them, and stacks them to produce astroimages that resemble long-exposure results even without an equatorial mount. It supports auto-brightness or HDR-style 16-bit TIFF outputs for post-processing, reduces random noise, applies light-pollution reduction, corrects wide-angle distortions, and includes features like sky masks, foreground detection, star-light enhancement, star-trails mode, and batch processing for time-lapse. The program aims to be simple yet powerful, automatically determining the best parameters to minimize trial-and-error.
