North­ern Logoon Neb­ula (NGC 7538)

Northern Logoon Nebula (NGC 7538) Astrophotography Martin Rusterholz

NGC 7538 (Sh2-158), near the more fam­ous Bubble Neb­ula, is loc­ated in the con­stel­la­tion Ceph­eus. It is loc­ated about 9,100 light-years from Earth. It is home to the biggest yet dis­covered pro­tostar (NGC 7538 S) which is about 300 times the size of the Sol­ar Sys­tem. It is loc­ated in the Perseus Spir­al Arm of the Milky Way and is prob­ably part of the Cas­si­opeia OB2 com­plex. It is a region of act­ive star form­a­tion includ­ing sev­er­al lumin­ous near-IR and far-IR sources. Stars in NGC 7538 are mainly low-mass pre-main-sequence stars.

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.
