Description

Not sure how to make the H-alpha jets stand out. I used the tone mapping technique with this data as if it were narrowband. Next time I'll try the conventional galaxy pipeline.

Filters ZWO LRGB:

Lum 22x120s + 23x180s + 26x 90s = 2 h 32 min

Red 37 x 180 s + 4 x 300 s = 2 h 11 min

Green 61 x 180 s = 3 h 3 min

Blue 60 x 180 s = 3 h

Astronomik 6mm H-alpha: 51 x 600 s = 8 h 30 min

Total integration time: 19 h 16 min
