All explained in the exposure details:
LRGB with special purpose Astrodon infrared filters. L is "infrared luminance" which excludes anything less than 700nm. Red is assigned to a band peaking at about 850nm, Green peaking at about 830nm and Blue at 750nm. Exposure times were L = 200 minutes (unbinned) and R = G = 100 minutes, B=130 minutes (binned 2x2)
