This is the next to highest numbered Sharpless2 Object... not a very notable image, but it is the top end of the list and depending on latitude hard to image. It is part of a much larger object.

There is one other image on Astrobin that isan excellent mosaic:

From GalaxyMap:

There is nothing much in the scientific literature about this object. BFS comments that it is "Too large and diffuse for meaningful observations".

This image shows only a tiny fragment of a vast region of nebulosity. It is the fourth object in the Sharpless catalog by area of apparent sky covered. Perhaps it is a fragment of the even larger Gum nebula?

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 312 Sh2 objects and those below 70 and above 283 are low on the horizon and difficult for me to image... this leaves me 212 that are feasible... and I have imaged all of these but the 13 of these are too big for my system. .

This image was the last image in the series and I may add some more if I can get closer to the horizon... 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 am steadily reprocessing the older data with more modern techniques.

This is my collection:

Sharpless2

Please note there is also a Sharpless2 Group with now more than 1000 examples.

Hope you enjoy these obscure but interesting objects...
