“I found this to be a very useful tutorial. It explained many aspects of PixInsight that were not intuitively obvious to me. I have tested the process on a number of my image data sets, and am very pleased with the results!”

Once you have learned the basics, you will be taught how to stack all your files within PixInsight. You'll first understand how to discard unwanted files so that they do not affect the Master file.

FAQ

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

    Not necessarily. We encourage you to use your own data, but also provide high-quality master files of the Pleiades 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.

  • 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?

    The course lessons are hosted on an online platform, but you will have the option to download the videos and watch them at any time, even when offline!
