Image Description and Details: Very faint supernova remnant in Cygnus. Designated SH2-91 or G65.3+5.7 it is a very large complex. I decided to go for a two panel HOO mosaic. I had a grand total of just over 52hours between the two panes and filters. There was some additional time to try and capture detail close in on Campbell's Hydrogen star. An amazing object by itself. While working on the first pane and exploring the image I found an amazing little gem of a planetary nebula. Technically it is a PN candidate, but looking at the image there is no doubt it is a PN. Campbell's hydrogen stars is an interesting item right in the middle of the field of view too. When originally looking around the image I thought for sure that was a carbon star, but pulling up my What's In My Image script it quickly identified it as a planetary nebula too! It is actually an object Hubble imaged, so I took a series of 30sec exposures to not blow out the core and see if I can see anything in there. Sure enough it appears as a bull's eye. A bright star surrounded by a bubble of hydrogen. I have a comparison with what Hubble saw, needles to say my set up is not Hubble It is only 4 arcsec across so I wasnt expecting much, but rotated to match Hubble has similar asymmetry! Below are a couple of close in crops of these amazing objects and just gorgeous views of the main object!
