Repeating one more of the Sharpless2 Group to see what my new CMOS system can find with a deeper look at the H-alpha here....
I also put up the raw destarred H-alpha with an interesting view of the PN low and right of center. Maybe a shock wave around it. Cannot barely see this is the RGB version.
Previous versions of SH2 119.
Sh2 119 HOO
Old version with the Tak 180ED... gotta love that F2.8 scope.
Sh2 119 Two Night's Images Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:Sh 2-119 is located near the North American nebula (
Sh 2-117, NGC 7000). Avedisova lists 6 ionising stars. The hottest of these is the O 7.5 III runaway star 68 Cygni (
HD 203064), which was likely blasted out of the Cepheus OB2 association about 5.2 million years ago.
It is also known as HS 240 = [GS55] 240. Good colour images of this nebula can be found
here and
here.
