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....
By popular demand, I also put up the raw destarred H-alpha.
Previous versions of SH2 127.

Sh2 127 Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:Radio analysis reveals that Sh 2-127 consists of two distinct components - a larger weaker and more diffuse source (WB89 85A) to the northeast, consistent with ionisation by an O7 class star, and a stronger but smaller source to the southwest (WB89 85B), consistent with ionisation by an O8.5 class star. (However, it is also possible that both components are ionised by a single star.) Both components are located near the northwestern edge of a molecular cloud and are embedded in the molecular gas.
According to a 1978 study, Sh 2-120, Sh 2-121, Sh 2-127 and Sh 2-128 are all at about the same distance of 7500 parsecs and are "probably distant HII regions associated with a spiral feature more distant than the Perseus arm".
GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>There are 313 Sh2 objects. All now imaged.
