The Scare­crow (IC 1613) in Cetus

IC1613 Galaxy Astrophotography Martin Rusterholz

The Scare­crow IC 1613 was pho­to­graph­ic­ally dis­covered in 1906 by Max Wolf. Although that this Irreg­u­lar Barred Dwarf galaxy in Cetus is shin­ing at 9th mag­nitude, its light is spread across an area of sky about the size of a quarter Moon. This extremly low suface bright­ness is the reas­on IC 1613 escaped from bee­ing dis­covered earlier.

IC 1613 lies 2.3 mil­lion light-years dis­tant, so it is as far as M31 and mem­ber of the Loc­al Group, and its dia­met­er meas­ures 12’400 light-years. Its interi­or looks streched, frag­men­ted, shorn and tattered from grav­it­a­tion­al inter­rac­tions in the past. The spa­tial dis­tance from Andromeda Galaxy is nearly 2 mil­lion light-years which is far too great to be con­sidered to be closly related.

Long expos­ure was needed to bring out some details of the galaxy and its HII region. North is up in this image.

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.
