PixInsight is a powerful image processing package that I've been using lately for my astro images. There is a lot of tutorial and other helpful PixInsight material on the PixInsight site and elsewhere on the web, but it's sometimes hard to locate specific items.
This page of useful PixInsight links is organized by broad topic, rather than format as on my other PixInsight Links page. I hope you find it useful.
