Kronberger 24 in Cygnus
Kronberger 24 (Kn 24) is a planetary nebula in the constellation Cygnus with a diameter of 190 arc seconds. It was discoverd by Matthias Kronberger, member of ‘Deep Sky Hunters’, a group of amateur astronomers, searching for unknown objects in DSS images. Kn 24 was listed as a probable and confirmed PN in this paper.
Sakib Rasool suggested this target which required long exposed Ha and OIII to bring out some details. North is up in this image.

Hello, my name is Martin Rusterholz. I’m a Swiss amateur astrophotographer living near Zurich, the biggest town in Switzerland. My interest in astronomy started when I was 16. At that time, I built my first Newtonian telescope and mount. I studied physics at the Swiss Federal Institute of Technology (ETH) which was the only study including at least some aspects of astronomy and astrophysics.
“Looking at the nights sky is an experience touching everybody deeply inside, something common to all human beings independent to the language spoken by the individuals”.
Deep-sky astrophotography is my passion.
