M106 (NGC 4258) in Canes Venatic

M106 (Messi­er 106 also known as NGC 4258) is a spir­al galaxy in the con­stel­la­tion Canes Ven­at­ici, dis­covered by Pierre Méchain in 1781. M106 is at a dis­tance of about 22 to 25 mil­lion light-years away from Earth. It is also a Sey­fert II galaxy, which means that due to x‑rays and unusu­al emis­sion lines detec­ted, it is sus­pec­ted that part of the galaxy is fall­ing into a super­massive black hole in the cen­ter. The small galaxy to the right of M106 is NGC 4248 shin­ing at 12.5 mag.

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.
