Escaping from Sadr influence the blazing butterfly illuminates the sky!
Ok no science here but a redux of 2019 data :)
Insanely hard streched data to do the trick and I also chose a warm deep color palette. O3 was a hell as usual despite 250mins...some many LP chunk goes through.

Pre-proc APP
Proc: Pix, PS and a denoise try with Topaz (used lightly for denoise and not sharpening - made my best to avoid the dreaded checkerboard pattern)

That was fun!
