Description:
This is truly a strange PN in that there are a few stars “embedded” in it.
Found a dim smudge at 22x and it’s relatively large (3.8') for a PN.  30x 
showed it as faint dim smudge with some stars inside.  Counted 6 stars at 60x 
and looked more like small OC with nebulosity, oval shape.  Best view.  See 5 
stars clearly at 110x with 4 stars clearly inside the PN forming a diamond 
shape: 11.7 mag GSC 5272:958, 11.8 mag GSC 5272:1890, 11.9 mag GSC 5272:1061 
and 12.2 mag GSC 5272:954.  Oval “rim” shape more pronounced due to darker 
background. Nebulosity is much dimmer than its 8.5 magnitude.  Nebulosity too 
dim and almost gone at 146x.  Later, I looked at my research and found this: 
Dreyer described it as "very faint, large, 4 stars in diffused nebula."   So 
they must be the 4 star diamond shape I saw.  This photo I found gave a good 
impression of what I saw (except what I saw was gray color and much dimmer.)
