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
Previous version of SH2 140. This is with my oold Takahashi 180 ED and 11h on the CCD. The second is 13h of RGB from SRO.
Sh2 140 in H-Alpha (with new mount) 
Sierra Remote Observatory (SRO) Sh2 140 LRGB Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:Sh 2-140 is part of the
Cepheus Bubble, the expanding shell of gas and dust surrounding the
Cep OB2 association. The bright rim is created by the B0.5 V double star
HD 211880 ionising a Bok globule located within the southwest side of the
LDN 1204 molecular cloud.
Avedisova identifies three other potential ionising stars, including the O7 V star
BD +62 2078. She places Sh 2-140 into the massive star formation region
SFR 106.75+5.30, and lists 79 components, including 7 masers and the dark nebulae LDN 1204 and
LDN 1206.
