Another version of this group with the absolute minimal number of frames due to the weather (half hour).
Used the new version of StarXterminator (2.0.1 AI 11- full AI). Very slow but you can use now faster AIs, but the star correction is excellent... also is the destarring.
Previouis version with 10+h on CCD shows much less Ha.
Sh2 147, 148, 149, 152 and 153 H-alpha RGB Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:Avedisova combines Sh 2-147, Sh 2-148 and Sh 2-149 into the star formation region
SFR 108.27-1.07, which is ionised by two uncatalogued O8 V and B0 V stars and includes the star cluster
King 10 and the young stellar object
2MASX J22555978+5814424.
Sh 2-147, Sh 2-148, and Sh 2-149 form one of the two cores of the 105 thousand solar mass molecular cloud
[UUT2000] Cloud A. (The other core is associated with Sh 2-152 and Sh 2-153.) This molecular cloud may be interacting with the supernova remnant
SNR G109.1-01.0 (CTB 109).
The molecular cloud can be seen in
this MSX infrared image. The same field at
radio frequencies reveals the supernova remnant.
