Description

Tonight, imaging from 21 o'clock till past midnight, I've been lucky with a stable sky so I could pursue this project on M27 in full :

F VERSION : color corrections, contrast and sharpness pushed on relevant parts, little extra crop ;
E VERSION : more O-III in the mix and more masks to make things sharp and less noisy... That's all folks.
