“I think overall this was an excellent tutorial. I moved away from PS, the learning curve for me was jumpy and all over the place form online sources,, Two weeks ago I downloaded Pixlnsight went through an in depth short course for the basic foundations and understandings to get me to a start point. If your a true beginner, maybe buy Galactic Hunter Beginner PixInsight Processing Guide, then move to this. This was exactly what I was looking for after that foundation study. This is targeted towards narrowband, causing me hesitancy as I only have a OSC, I do use dual/tri band filters with the OSC, and if I wanted to keep the channels separate during processing this tutorial has given me great insight in how to do that. I also had no issues following the process just using OSC data. Nothing less than a 10/10 here, two slightly different workflows would be have been nice though, maybe with two different Nebula. The interface is seriously 10/10, great job! Ease of Use 10/10 Value 10/10 Awesome job!! ”

FAQ

  • Do I need my own Milky Way files to use the course?

    Not necessarily. We encourage you to use your own data, but also provide high-quality master files of the Milky Way that we shot from the Nevada desert! You can download these files to follow along and do exactly what we do in the videos with the exact same files. This is great if you'd like to practice before using your own data.

  • Who is this workflow designed for? Beginners or experienced astrophotographers?

    Both! The course is designed to be easy to follow, no matter your skill level. What is important though is to know the basics of PixInsight (how to navigate the dashboard, stretch an image, open files...). If you have never used PixInsight before, we strongly suggest going through our PixInsight Beginner Workflow first!

  • How long will I have access to the course material?

    Courses that are purchased individually give you lifetime access with no expiry date. Bundles on the other hand, which include all courses at a low price, have a small yearly renewal fee. More info on that can be found on the bundle pages.

  • What kind of support is available if I have questions during the course?

    We receive a lot of emails and messages on social media each day from people seeking help with astrophotography. We do our best to reply to everyone, but it is not always possible. We prioritize emails from both Galactic Course members and Patreon.

  • Can I access the course on mobile devices?

    Yes, you can access the course on any device, which include computers, tablets, and smartphones.

  • Can I access the course offline?
