Sh2-129 and OU4 in Ceph­eus is a real­tively faint neb­ula in the North­ern con­stel­la­tion Ceph­eus, also know as “Fly­ing Bat” neb­ula. In 2011, French ama­teur astro­nomer Nic­olas Out­ters dis­covered a faint OIII emis­sion with­in Sh2-129 which nick­name became “Squid Neb­ula” accord­ing to its shape, it’s offi­cial name is OU4. The small emis­sion neb­ula below Sh2-129 is vdB-140.

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.
