Course Description
This course is a treasure trove of solutions, techniques, and insights—curated from years of real astrophotography experience and designed to save you from frustration, wasted time, and the feeling of “why didn’t anyone tell me that?”
Many of these lessons are born directly from challenges faced by imagers like you: how to fix scattered light, remove star color fringing, prevent over-subtraction, correct flat-fielding errors, and more. Other videos explore innovative methods—like Adam Block’s original star de-emphasis techniques, advanced mask usage, or selective rejection strategies—that you simply won’t find elsewhere.
It’s not just a catalog of fixes; it’s also packed with creative techniques and deep diagnostics that help you better understand what’s happening in your data—and how to take control of it.
Yes, you might come here for one solution. But you’ll leave with tools you didn’t even know you needed—until now.
