Lynkeos
Lynkeos is a free, open-source Cocoa application for processing astronomical images captured through telescopes using webcams or digital cameras. It is primarily used by amateur astronomers and astrophotographers for image stacking, alignment, and enhancement of planetary and deep-sky observations. The app supports a range of input formats including video sequences, 16-bit TIFF and FITS images, and includes features for wavelet processing, deconvolution, and quality-based frame selection. It runs natively on both Intel and Apple Silicon Macintoshes.

1 suggestionLynkeos already ships as a native Apple Silicon build — the SourceForge project page confirms the app "runs natively on Intel and ARM Macintoshes" since version 3.6 (released in 2020). If you are still running an older Intel-only version of Lynkeos, simply download the latest release from https://sourceforge.net/projects/lynkeos/files/ to get the native build. The current version runs on macOS 10.13 and later, so there is nothing preventing you from upgrading today. After updating, you will see noticeably better performance and battery life during image processing compared to running the old Intel build under Rosetta.
