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.

About Me

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.
