Your Best Astrophotography Images Are Buried in Your Bad Frames

Stop guessing which frames to keep. This scientific method guarantees sharper stars. In this video, we dive deep into the "Boring Middle" of astrophotography processing: Culling. Most beginners just guess or delete blindly, but using FWHM (Full Width at Half Maximum) allows you to mathematically prove which frames are ruining your stack. I'll show you how to automate this in Siril so you never have to manually inspect 500 subs again. ☕ Fuel my sleepless nights & get cleaner images: https://buymeacoffee.com/astroimagery 📥 Download the Astro Imaging Cheat Sheet: https://astroimagery.com/getcheatsheet/ Visit the Astroimagery Shop: Every image in my shop was captured the old way — hours of manual imaging, no automation.
