Description

Bubble Nebula is one of my favorites on the sky. This HRGB did raise some challenge in balancing the H/RGB. I extracted L from RGB and did a max selection.

Version B has Oiii mixed into blue channel, reveals the blue tint of the bubble and the "platform" of it while maintains the background's color.
