Mastering PixInsight
“Mastering PixInsight” does much more than covering PixInsight from A to Z. In addition to including the most complete PixInsight Reference Guide on the planet to date, the book takes an intimate look at RBA’s huge private repository of countless personal processing tips, “tricks”, methods and know-how accrued over more than ten years.

RBA’s PixInsight Processes Reference Guide (2nd edition)
This is the most complete and up-to-date Reference Guide of PixInsight processes we can find today. By far. Period. There’s nothing like this anywhere. Not yet. If you find it, let us know, we’ll change our statement and we’ll give you a copy of both books for free.
This guide documents every process available in the PixInsight official distribution (*) and every single parameter in every process – what they are, what are they for, how to use them… That’s more than 100 processes fully documented!
The guide is aimed at being useful to novice, intermediate, and advanced image processors alike. This means the guide reaches a moderately advanced level, which may make it a bit hard to read by those fairly new to astroimage processing. Novice users will also benefit from the book Mastering PixInsight and the art of Astroimage Processing, where we can find workflows, techniques, and many practical examples illustrated with real data that are explained at a pace that’s easy to follow. This guide is meant to be mostly used as… a guide.
What this Reference Guide does not do:
-
-
It does not teach how to process our images.
-
It does not show practical examples or tutorials.
-
It does not explain how PixInsight’s user interface works.
- It does not document PixInsight’s scripts, only processes and modules. Script documentation is currently a work in progress.
-
For all of the above and more, refer to the Mastering PixInsight book.
What this reference will (hopefully) do for you:
-
-
Provide a comprehensive description of each of the over 100 processes in PixInsight. What they are, how they work, when to use them, and what they can do for us.
-
Describe every parameter – even the most obscure ones – in every process, some extensively, as well as the effects of adjusting many of them, particularly those that tend to be more useful.
-
Offer suggestions about the use of a particular process within a processing workflow, when and how to use it, etc.
- Everything in one place. We can search the whole PixInsight process documentation at once, print any parts of it if we like, carry it with us anywhere in our phone, the cloud, etc.
-
This Reference Guide is based on PixInsight Core version 1.9.3, with the latest updates up to February 2026.
Mastering PixInsight (1st edition)
These are some of the things you will find inside Mastering PixInsight:
-
Not just for beginners, not just for experts. Everyone wants to produce great astrophotos, but everyone also has different processing skills and goals. Mastering PixInsight starts at the very beginning: installing the software! It introduces it gently, then it starts with a complete workflow aimed at those who have never used PixInsight yet.
-
With that done, the book makes sure we get to know every other details about using PixInsight until there’s little left.
-
Then it spends a good part of the book doing a new processing round from the beginning, but this time not leaving anything behind.
-
The book continues covering some individual topic in great detail: preprocessing, narrowband, mosaics of any size, HDR, gradients, AI tools, etc.
-
It wraps up introducing parallel workflow, and a few other things.
