I included the best HA frame since it plate solves the best and there seems to be a planetary nebula off to the left. The main object is the thin g on the Right.
Some of the subs had StarLink trails in them, which is a real PITA. There is a good picture of what I saw in an image of Sh2 14:
Sh2 14 (Nothing There Except Starlink), which is not really a Sharpless Object.
From
GalaxyMap:This HII region is ionised by the O8 V star HD 161853 and is part of the Sh 2-15 to Sh 2-20 complex of HII regions located in the Sgr OB5 association in the Sagittarius arm. It is the location of the radio source W25[color=#ffffff].[/color]
GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>
I have been on a project for several years now to image all the Sharpless2 Objects that I can see from my location near San Francisco. I chose these because they are visible in light polluted areas. These objects generally represent left over Hydrogen along the edge of the Milky Way that has gotten molded into interesting shapes.
There are 313 Sh2 objects.
As of the date when this image was posted:
I had imaged 270 (86%).
There are 12 too diffuse/large to image with my set up (Sh2 111, 117, 122, 131, 132, 145, 178, 218, 221, 230, 268 and 310). I may look for other images so I can get a complete collection.
There are 5 that are never above 14 DEG (Sh2 2-6) [Edit 7/12/21- I can get these now with pier upgrades and the images are completed as best as I can].
These remainder are in Expert Scheduler waiting for them to pass by.
The first one was taken on December 23, 2013.
Many were taken with my old Tak 180 ED, which had a wide field of view, but was replaced with my Stellarvue 130, which is more narrow field. I have also taken two very wide field HA images with my Nikon D800 and a 50mm lens.
This is my collection:
