Description

This is a rarely imaged object from the Sharpless catalogue. Some of it is also catalogued by Lynds, containing a dark nebula (LDN 1563) and bright nebula (LBN 838).

I can only find three other images of it on Astrobin. @Jerry Yesavage , the great collector of Sharpless objects, calls this one dull and obscure. My hope was that the RASA at f/2 would prove him wrong and I think it partly did. In a recent image by @Gary Imm he points out that it is most likely a molecular cloud. Much of it looks like that, even IFN, but my image shows that there are some colors there and actually quite a bit of Ha emission around the nebula. I think I also see at least one blue reflection nebula.
