Eise.app is described as 'An easy planetary image stacker for astrophotography' and is an app. There are six alternatives to Eise.app for Windows, Mac and Linux. The best Eise.app alternative is RegiStax, which is free. Other great apps like Eise.app are Planet Stacker X, Autostakkert!, WaveSharp and Planetary System Stacker.
Planet Stacker X is a powerful, Mac-native application that brings professional-grade planetary imaging within your reach.



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.
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.
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.
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.
