Description

This is my 3rd attempt at this target, first from dark skies. This is a little over 3 hours total integration time from Bortle 5 skies, whereas in the past I've had to shoot close to 30 hours to see any definition in the dark structures. 

For this attempt I also used my Antlia RGB Ultra filter. I noticed that it helped maintain a better contrast between the Flame's red/orange and other Ha regions. I've struggled with this in the past and I'm not sure if it was the filter or dark skies that helped more here, I'm suspecting the latter.

IC434:
Lights: 95x120s
Gain: 100
