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.....
A Previous versions of SH2 130 with more detail of the object itself using 9h on the CCD, but same scope. Dull by comparison to the 2.5h on the CMOS with the same scope.
Sh2 133 HA RGB Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:Sh 2-133 is probably a part of a chain of ionized arcs surrounding the older group of the Cep OB2 association and is located at a distance of about 800 pc.
Sh 2-131 and several other H II regions, such as Sh 2-129, Sh 2-133, Sh 2-134, and Sh 2-140 are apparently parts of the Cepheus bubble.
