Description

Hello Friends,

this is a small an rarely images PN of the fairly new type of quadrupolar planetary nebula. I did a short research but there is only little information about.
It's shape is like an "8" and has a magnitude of approx 16.5m. It is very faint and was a coincident when imaging the SH2-114 Flying Dragon.
I decided to upload it separately to make it available in the search if someone searches some images.

I know, not breathtaking, but rare and interesting.

Please enjoy!
Rüdiger

Update 2021-09-03:
Kn26 was discovered by Austrian amateur astronomer Matthias Kronberger in 2006,and  spectroscopically confirmed as a planetary nebula 2011.
