Another version of this group using my new CMOS camera. Trying to get the most detail of the bright core of the central nebula I used HDR techniques with 450s and 45s H-alpha exposures.
The bright core is only one of five distinct and apparently independent emission sources within a giant molecular cloud. Might be an interesting target for those with big scopes.
I also dithered the images and carefully stretched with GHS.
Also 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 removal is excellent.
Previous version from a long time ago on CCD.
Sh2 156 IC 1470 H-alpha RGB Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:Also called IC 1470, this HII region is part of the star cluster
NGC 7510 according to Avedisova. It appears to be ionised by a single O7 class star.
The bright core is only one of five distinct and apparently independent emission sources within a giant molecular cloud.
Avedisova places Sh 2-156 in star formation region
110.12+0.04 with 35 components, including 7 masers, the reflection nebulae
[SS62] 71 and
PP 104 and the HII regions
BFS 15 and
BFS 16.
Russeil expands this star formation region and adds the HII regions
BFS 14,
BFS 17 and
BFS 18 as well.
GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>There are 313 Sh2 objects. All now imaged.
