NGC 3953 in Ursa Major

NGC 3953 Galaxy Astrophotography Martin Rusterholz

NGC 3953 belongs to the Ursa Major Cluster of galax­ies, some 50 mil­lion light-years dis­tant. The appar­ent dia­met­er of this bared spir­al galaxy meas­ures 6.0x3.2 arc min, which coresponds to about 90’000 light-years in reality.

The Ursa Major Cluster con­sists of at least 79 mem­bers accord­ing to vari­ous papers. Beside the low-sur­face galaxy UGC 6840/​PGC 37164 vis­ible in the upper left part of this image, NGC 4051 and NGC 3729 are addi­tion­al bright mem­bers of this cluster.

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.
