Dumbbell in NHO

[DaveS]

Finally managed to get somewhere on a long standing project, to image M27 in NHO

This is something of a first pass, consisting of 3 hours each [NII], HII and [OIII] in 10 min subs with the 130 triplet and ASI 1600. Stacking and RGB synthesis followed by DDP, a few rounds of Histo Stretch followed by a touch of Unsharp Mask in AstroArt 7

This has had a moderate crop to remove alignment edges. Need a lot more data, as the outer shells are only just visible. Looking at the distribution of lines, I think as much again [OIII] and [NII] will bring out the outer structure.

V nice, Im working towards a SHO image of this target, got the Ha and Oiii but strugling to find a clear window for Si. Hope mine comes out as good as this.

Stunning, lovely image and just a hint showing of the outer fans.
