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 134 with more detail of the object itself using 5h on the CCD, but same scope. Dull by comparison to the 2.5h on the CMOS with the same scope.
Sh2 134 HA RGB Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:This HII region is associated with an expanding bubble surrounding Cep OB2. Also associated with this bubble are the HII regions IC 1396 (also called Sh 2-131), Sh 2-129, Sh 2-133, and Sh 2-140.
Avedisova concludes that the 40 solar mass O6 Iab supergiant Lam Cep (
HD 210839) is the exciting star for Sh 2-134. You can read about the controversy around the origin of this great Milky Way beacon star in the
Cep OB2 section of the
Clamshell (110° - 100°) sector portion of the
Commentary on the Galactic Plane.
