M27, now in H-alpha

[AstroAndy]

Hi all

Another M27, this time with H-alpha added: I set out to capture the outer shell, no matter how little or much. It may not be perfect, but I'm happy with it. 2x15min, 2x10min, 31x5min, RGB 5x5 in each channel, bin x1, altogether 4:40h of exposure. This is an HaRGB image, Ha integrated into red, and the separate HaR used as luminance.

that outer shell is showing up real nice

Just a tad, ?.

It looks great... the outer shell is coming through too.

Thanks Mars...I was ambivalent about this process (HaR as a luminance layer rather than pure ha), but now I like it.
