New nebula discovered
This very faint nebula was discovered last year. They are calling it a planetary nebula because of its shape, but its size and internal structures don't fit. Or it could be a supernova remnant, or something else entirely.
It is called StDr56, and it is located in Triangulum.
The photo, which is not mine, took nearly 60 hours of exposure time!

Re: New nebula discovered
Interesting object. I like the characterization as a supernova remnant, but supposed they would have to know there was an SN there at one time. Or we'll have to start calling the Veil Nebula complex a PN . Thanks for sharing the find, Kathy.

Re: New nebula discovered
Looks like a supernova remnant - just doesn't seem to be an emission or reflection nebula.

Re: New nebula discovered
really pretty and very interesting as an object.
it gives the impression of a remnant of a supernova.

Re: New nebula discovered
Here is another article, by Phil Plait, about this object. Personally I can see some visual traits of a planetary nebula, though indeed it is a bit unique in appearance. Obviously bears more research.

Based on the coordinates used by Robert Pölzl, below is a chart I made in Sky Tools 3 showing its approximate position, It is plotted to stellar magnitude 12.0.
Coordinates: 02:07:17.41 +30:05:11.90 (J2000)

Re: New nebula discovered
There is a type of soft bodied oceanic creature that looks like that.
That is an interesting object. I don't think I will get out my 60mm refractor in myBortle 6 back yard to look for it though.
