Description

Revision: G

Description For this revision I utilized arcsinh stretch for the RGB integration. This allowed me to retain a TON of color data that I washed out with my previous histogram stretch. This includes the orange glow in the galaxy core as well as the blue and red in the spiral arms particularly near the galaxy core. Stars across the image have better colors as well, particularly the fainter orange stars. -
