Needle Galaxy (NGC 4565) in Coma Berenices

Shin­ing at a maginitue of 9.6, NGC 4565 appears as a 16′-long needle of light. The flattened disk dis­plays bright and dark patches with much clump­i­ness and branch­ing. As with NGC 891, pho­to­graphs also show dark fin­gers of dust pro­ject­ing above and below of the equat­ori­al plane.

We now know that NGC 4565 is a mem­ber of the loc­al Coma-Sculptor group. With an accep­ted dis­tance of 32 mil­lion light-years, the true dia­met­er of the galaxy is about 150’000 light-years.

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.
