Another recast of a Sharpless2 object. Background comes out with the GHS stretch and the CMOS camera.
Here I include the destarred H-alpha original to give some idea of the detail I am getting from the combination of the CMOS and GHS. It shows the underlying structure of SH 99 and 100 is in common.
LBN 156 was identified well in the lower right corner.. looks like an "X".
GHS Forum DiscussionFrom GalaxyMap:This star formation complex is embedded in the massive W58 radio source and molecular cloud, and is catalogued by Avedisova as
SFR 70.29+1.60. The region also includes Sh 2-100, 5 masers, and numerous additional radio and infrared sources including 7 HII regions.
Available distance estimates suggests that the W58 molecular cloud is located in the Perseus arm.
The W58 region can be seen in this
MSX infrared image.
