This one is pretty dull but the AI helped in keeping acquisition time to a minimum.
From GalaxyMap:
Although usually classified as an HII region, this peculiar high latitude nebula, also called LBN 102, looks more like a dust cloud in this image, and indeed this object is in the same direction as the small molecular cloud [CB88] 124.
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 244 (78%).
There are 12 too diffuse/large to image with my set up.
There are 6 that are never above 14 DEG elevation at my site and are too low for my 17 DEG min due South.
This leaves me 51 potentially still do-able and most 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:
