Description

Found kicking around the work in progress area... same area I am putting up from the Stellarvue today. Originally acquired 2016-11-15.

From GalaxyMap:

Sh 2-231 to Sh 2-235 form a complex of HII regions located together in the Perseus arm in the outer galaxy. This complex may be associated with an old (330 thousand years) supernova remnant, FVW 172.8+1.5.

There is a giant molecular cloud, G174+2.5, containing Sh 2-231, Sh 2-232, Sh 2-233, and Sh 2-235 that is at a distance of about 1800 pc.

This is a detailed image centerdd more or less on 231:

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 31. 13 of these are too big for my system. 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:

Sharpless2

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

Hope you enjoy these obscure but interesting objects...
