“Awesome Job!! 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 you're a true beginner, maybe buy Galactic Hunter Beginner PixInsight Processing Guide, then move to the others. 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. [Now included]. The interface is seriously 10/10, great job! Ease of Use 10/10 Value 10/10 Awesome job!!”

FAQ

  • How does support in the Galactic Course work?

    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.

  • Do I need a telescope (or gear) to use the course?

    Not necessarily. Some seasons focus on astrophotography with a telescope, but you don't need a telescope or gear right out the gate. Rushing into making a purchase is not what we intend to teach. We encourage following along before making an expensive purchase that might later be regretted.

  • Why does the bundle have a yearly dues?

    The Galactic Course is a growing library of astrophotography content. As such, it takes tremendous effort to curate lessons, as well as write, film, edit, and revise content to complete the end product. Yearly dues support the Galactic Course mentors' work in creating new lessons and guides. Yearly dues are only for members that are in the subscription model. Students who have lifetime access do not pay these dues.

  • What happens if I don't pay my yearly dues?

    [This does not apply to lifetime members who paid a one time fee] No matter the bundle, subscribed members are subject to yearly dues in order to retain access to the Galactic Course. Otherwise, they will not be able to access the content. A member is not obligated to pay their dues if they wish to stop learning with the Galactic Course. Non-active members can regain access by paying the yearly dues.

  • What if I only want a specific course or want a specific guide?

    You can purchase specific course lessons or processing guides separately. Only pay for the course materials you want to learn from. However, it may become more costly than a bundle so be sure to weigh your options. While there is no obligation to buy the Ultimate Bundle, the biggest benefit of investing is getting access to all course materials and processing guides, plus perks!
