Pin­wheel Galaxy (M33) in Triangulum

M33 is the third biggest galaxy of the Loc­al Group after the Great Andromeda Galaxy (M31) and the Milky Way with a true dia­met­er of 50’000 light years and a dis­tance of 3 mil­lion light years.
Wil­li­am Her­schel cata­logued the bright­est and largest HII region (lower right of the cen­ter) as NGC 604, with a dia­met­er of about 1500 light years, roughly 50 times big­ger than the Ori­on Neb­ula (M42).

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.
