PixInsight is AnPHunt software of choice for processing astronomic images. A must have for the serious astrophotographers. 
Briefly, PixInsight is an advanced image processing software platform. It has been designed specifically for astrophotography and other technical imaging fields. PixInsight is a modular, open-architecture system where the entire processing and file handling capabilities are implemented as external installable modules.

PixInsight has been ported as a native 64-bit application to Linux, macOS and Windows operating systems. PixInsight is a strongly multithreaded environment able to exploit all processors and processor cores available on modern hardware.

PixInsight is both an image processing environment and a software development framework. The core PixInsight application integrates three user interfaces: a graphical interface, a command-line interface, and a scripting interface based on the JavaScript language. As a development platform, PixInsight provides the PixInsight Class Library (PCL), an ISO C++ framework for development of PixInsight modules, and the PixInsight JavaScript Runtime (PJSR), an ECMA 262-5 compliant environment readily available in the core PixInsight application.

The PixInsight project originates from the inside of astrophotography: PixInsight is a software platform made by astrophotographers, for astrophotographers.

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.
