3C 58 (SN 1181) in Cassiopeia

3C 58 is a small obscure super­nova whose optic­al com­pon­ent was dis­covered in 1977 by Sid­ney van den Bergh on long exposed plates from the 5m reflect­or at Mt. Palo­mar. It is the rem­nant of SN 1181 mak­ing it young­er than the Crab Neb­ula but older than Cas­si­opeia A. The size is about 6x10 arcminutes and required long Ha and OIII exposures.

The small plan­et­ary neb­ula to the right of the image is G130.4+03.1 (PN K 3–92) dis­covered by Kohoutek 1972. North is up in this image.

The ori­gin­al paper about the dis­cov­ery of the optic­al com­pon­ent of 3C 58 can be found here.

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.
