GalaxyMap did not have any information on this. Could not find any other images, so I uploaded the wider field H-alpha. Normally all my final images are cropped to 500x500 pixels for size comparisons. In any case, when I plate solved it, it came up as Sh2 239.
This was identified through ACP Expert Scheduler, which uses most standard databases.
The SkyX gives different coordinates as do other citations... there are few.
Anyway, I put it in here as a reference in case anyone searches and tries to image 243.
I think it is "lost in space".
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 and those below 70 and above 283 are generally too low on the horizon for me to image... this leaves me 213 that are feasible... and I have imaged all of these but 23. 13 of these are too big for my system. So 10 to go.
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.
This is my collection:
Sharpless2Please note there is also a Sharpless2 Group with now more than 1000 examples.
Hope you enjoy these obscure but interesting objects...
