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.
