Reworking M81 and Needle Galaxy using Refine Edges and Lab Color

I reworked my images of Galaxy M81 (Bode's Galaxy) and the Needle Galaxy (NGC4565). Starting from my APP stacked image (Tiff) I used color range (NL kleurbereik) and Refine Edges (NL Hoeken verfijnen) to select the galaxy. Next I changed the brightness, contracts and colors. The finalize I changed from RGB to Lab Color and change brightness again using "bringhtness Channel". Before saving I RGB was selected again. Noise was reduced using DeNoise AI.
