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..... Also including reference to the older with a CCD.
Previous versions of SH2 130 with more detail of the object itself using 9h on the CCD, but same scope.
Sh2 130 HA RGB Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap: [Seemed Bogus}From Sharpless CatalogSh2-130 lies in the western area of Cephus and is on the smaller size in the catalog. The larger nebula to the[ lower left] upper left area does not seem to have a catalog number but offers wide field systems something to add to the image. For a larger telescope, SH2-130 itself seems to have some interesting detail and structure. However, this one is not bright so some exposure time is needed. There is a very weak reflection nebula around the entire nebula but is barely visible in this image. The nebula responds quite well to the hydrogen alpha filter.
GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>There are 313 Sh2 objects. All now imaged.
This is my collection:
