Repeating one more of the Sharpless2 Group to see what my new CMOS system can find... slightly longer exposures than usual. GalaxyMap refers to an "Aquila Rift" in this region, perhaps the un-named H-alpha in the upper left quadrant.
Previous CCD versions 10h on SH2 75.

Sh2 76 HA RGB Discussion of GHS aspects of processing:
GHS Forum DiscussionFrom GalaxyMap:There is very little to report about this faint, obscured nebula located above the galactic plane except that ammonia was detected in this direction in a 1996 study and it is prominent in infrared as can be seen in
this MSX image.
Sh 2-76 and several other prominent infrared sources are also located in a similar direction suggesting that there is something interesting in this region but there is little in the scientific literature about it. It is also significant that
millimetre emission suggests the presence of dense molecular clouds in this direction. In
this poster, the region is labeled
"Aquila Rift".
GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>There are 313 Sh2 objects. All now imaged.
This is my collection:
