I took images of the Dumbbell Nebula M27 over several nights with a remote telescope in Utah using LRGB and narrowband filters (H-Alpha, SII, OIII).
This data was helpful:
For: 6 x 120 seconds = 12 minutes
R: 7 x 120 seconds = 14 minutes
G: 5 x 120 seconds = 10 minutes
B: 7 x 120 seconds = 14 minutes
Height: 14 x 240 seconds = 56 minutes
Q: 14 x 240 seconds = 56 minutes
S: 5 x 240 seconds = 20 minutes
While processing the images, I couldn’t decide which combination of different shots I liked the most. So I just created a board with 4 different shapes.
