12-inch f/10 SCT (95x, 218x, 346x)

I had to go back and only had success after the second night trying to observed this small, very faint object. First impression appears just like a small-elongated galaxy. I estimate this elongated nebula N-S just about 1' in size. It appears with careful observation like two out of focus 11Magnitude stars closely on top of one another. The double lobbed nebula appears even in brightness except for a small broken middle area. Very difficult and need a lot of patients and skill to observed.
