Messier 81 & 82
by CSP of Xingming Observatory.
L: 15x300s
RGB: 5x300s each
Processing Regular LRGB combination with an exception: because the L was taken earlier while the moon is still on the sky, the signal-to-noise ratio of the L component is even lower than RGB's. So, I created the luminance layer by combining the luminance information from RGB and the L component (actually, L contributed less than RGB's).

Drizzle by 2 since Version B.
