NGC 3486 in Leo Minor
NGC 3486 is a barred spiral galaxy located about 27.4 million light years away in the constellation of Leo Minor. It’s apparent size measures 6.6′ x 4.7′ and it shines at mag 10.5. It has a morphological classification of SAB®c, which indicates it is a barred spiral with an inner ring and loosely wound arms. This is a borderline, low-luminosity Seyfert galaxy with an active nucleus. However, no radio or X‑ray emission has been detected from the core, and it may only have a small supermassive black hole with less than a million times the mass of the Sun.
North is down in this deep exposed image, which shows objects fainter than mag 21.5.

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.
