Looking at Sh-308 in today's APOD ( https://apod.nasa.go...d/ap200302.html ) in my opinion, there is a second planetary mixer as shown in the photo.

 

Has it already been identified and cataloged?

 

Friends, I await data on this.

Looks like a distinct possibility.  I can see it in another online image as well, so it is not a simple artifact.  While it could be a chance alignment of filaments of the same nebula, it instead appears to have a different color (and therefore composition.)

Yes, Redbetter.

In other photos it stands out well.
In my humble opinion it is a Planetary nebula independent of Sharpless 308.

Look second photo.

So, fascinating. I looked this up in Stellarium, and it is shown there as pn g234.9-09.7 I googled that, and there is a mention of it in the APOD discussion page at  https://asterisk.apo...=40327&p=300073

It was discovered in 2008 as part of the MASH II catalogue of PN. Also known as MPA0656-2356
