Description

This is a very interesting target. It's very active, even through milky way's dust clouds, it still shines in blue under RGB. Under narrow band filters, we can see large active areas, and what's more interesting is that I'm getting even stronger Oiii signals than Ha from it. Well I hope that's not a mistake.

Integration time:
 536 x 300 of LRGB
163 x 900 of Ha and Oiii
