PixInsight
PixInsight is a professional astrophotography image processing platform developed by Pleiades Astrophoto. Unlike traditional image editors, PixInsight treats astronomical images as scientific data rather than photographs, enabling non-destructive processing workflows that preserve linear data integrity through calibration, registration, integration, deconvolution and noise reduction stages. It features a modular architecture, scriptable processing pipelines via a JavaScript runtime, and support for astronomical formats including FITS and the vendor's native XISF (Extensible Image Serialization Format). PixInsight is widely used by amateur and professional astrophotographers worldwide and is considered the industry standard for deep-sky image processing, though it carries a steep learning curve. The platform is sold as a one-time purchase license.

1 suggestionPixInsight shipped its first native Apple Silicon (ARM64) build as of version 1.9.4 Lockhart, released in May 2026. If you are still running an older Intel-only version under Rosetta 2, you should update to the current native build, which benchmarks show runs approximately 30% to 65% faster on the same hardware (with CPU performance nearly doubling in some workloads). Visit pixinsight.net to download the latest version; the installer automatically serves the ARM64 build on Apple Silicon Macs. Note that version 1.9.4 also upgraded the JavaScript runtime from the legacy SpiderMonkey 24 engine to Google's V8, which improves both performance and script compatibility, so any custom PJSR workflows may need minor updates. Existing PixInsight licenses do not require reactivation when updating from version 1.8.6 or later. Licensed users can download both ARM64 and x86 builds from the official site if needed for compatibility testing.
