Nebula PixInsight Processing Workflow now available!

Updated: Apr 20

Our Nebula PixInsight Workflow is now available! It is an easy-to-follow course that takes you through all of the processing steps we use to process monochrome astronomical images, specifically nebulae. This is a great resource for any amateur astrophotographer who wants to become better at processing data using PixInsight. The guide was designed in a way that you can easily leave it open on a side window while processing and quickly follow each step as you go.

What does it include? Find out below!

Our Astrophotography Processing Workflow

We decided to make an advanced guide that will not only be helpful for RGB data but also for Monochrome images. In this course, we use NGC7000/IC 5070, the North America and Pelican Nebulae as an example, and process the image from start to finish using some more difficult steps that aren't included in our beginner guide.

As promised when we released it, the guide has been updated several times throughout the years to match PixInsight's newest versions and to add more tips and tricks we discovered over time.

As of today, the course includes 20 lessons, our raw data, and 18 walkthrough videos with commentary. You'll also be able to download our custom PixInsight process icons that includes all our pre-sets!

Oh, and it also has a section that covers how to download and process professional data from NASA and space telescopes!

The course is formatted in a way that it is very easy to read, simple to follow, and does not drag on forever! Each step fits on one page so that all information is given straight to the point. To make things even easier to follow, the processes described in this guide also have an embedded tutorial video showing you exactly how to apply the process.

The Beginner Processing Workflow

Not sure if you'll stick to PixInsight? Many of you found our original Processing guide really helpful, and we thank you for the nice feedback! This guide shows how we process our RGB images from start to finish. This is a great and easy-to-follow guide that is perfect for beginners who want to process galaxies, clusters, and other broadband targets exactly the way we do it. We used the famous Pleiades Cluster (M45) as an example in the guide.

You will have access to both written and video walkthroughs, the raw data of M45 for you to practice or follow along, our process icons, and more. We only recommend getting this guide if you are taking your first steps in the world of PixInsight.
