Omega Cen­tauri Cluster

Omega Cen­tauri (ω Cen, NGC 5139, or Cald­well 80) is a glob­u­lar cluster in the con­stel­la­tion of Cen­taur­us that was first iden­ti­fied as a non-stel­lar object by Edmond Hal­ley in 1677. Loc­ated at a dis­tance of 17,090 light-years (5,240 par­secs), it is the largest-known glob­u­lar cluster in the Milky Way at a dia­met­er of roughly 150 light-years. It is estim­ated to con­tain approx­im­ately 10 mil­lion stars, and a total mass equi­val­ent to 4 mil­lion sol­ar masses, mak­ing it the most massive-known glob­u­lar cluster in the Milky Way.

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.
