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.

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.
