Description

LRGB images of galaxies are difficult for me. Especially when I'm still experimenting with my setup, exposure times, and have more than one camera rotation angle. After integration, it is difficult to achieve a nice uniform background with my setup and skill level. I'll keep trying. I have H-alpha data for this, but for now, an LRGB version.

L = 9.2 h over 4 nights between Feb 19 and Mar 4, 2021

R = 6.9 h over 4 nights between Feb 19 and Mar 7, 2021

G = 4.9 h over 2 nights between Mar 6 and Mar 7, 2021

B = 4.5 h over 2 nights between Mar 6 and Mar 7, 2021
