RegiStax is described as 'Is image processing software for amateur astrophotographers, released as freeware, which runs under Windows. Its purpose is to produce enhanced images of astronomic observations through combining consecutive photographs (an image "stack") of the same scene' and is an app in the education & reference category. There are six alternatives to RegiStax for Windows, Mac, Linux and Web-based. The best RegiStax alternative is Autostakkert!, which is free. Other great apps like RegiStax are Planet Stacker X, Eise.app, Planetary System Stacker and WaveSharp.
AutoStakkert! is all about alignment and stacking of image sequences, minimizing the influence of atmospheric distortions (seeing). Its goal is to create high quality images of the Planets, the Sun, and the Moon, without too much hassle.
Planet Stacker X is a powerful, Mac-native application that brings professional-grade planetary imaging within your reach.
Produce a sharp image of a planetary system object (moon, sun, planets) from many seeing-affected frames according to the "lucky imaging" technique. Runs on Mac, Windows and Linux.
WaveSharp is a free, 64-bit image processing software specifically designed for planetary, lunar, and solar astrophotography. Considered a modern successor to the widely used Registax 6.
Combines stacking, wavelet sharpening, and color balancing into one tool. Many users find its wavelet sharpening to be superior to Registax and report that it produces fewer artifacts on lunar images than AutoStakkert.
