Horse in flames - A H-alpha project
Hello from Austria!
Actually, I just wanted to create an H-alpha image to boost the RGB version with it, but then everything turned out differently.
The moon was already too bright for RGB and since I had three clear nights I collected narrowband data.
The calibration, the stacking process (H-alpha algo) and the gradient removal were done in the APP. The final editing steps were done in Photoshop.
Full resolution and all details can be found here: https://www.astrobin.com/gmatk3/
I'm looking forward to your feedback 🙂
I think that's looking great! Nicely balanced, not too dark in the background etc.
