Pick­er­ing’s Tri­angle in Cygnus

Pick­er­ing’s Tri­angle is the middle part of the Cygnus Loop, a super­nova rem­nant with an age of about 15’000 years. It is much faint­er than NGC 6992 (East­ern Part) and NGC 6960 (West­ern Part) and has no NGC num­ber assigned. It was dis­coverd by Wil­li­am­ina Flem­ing but cred­ited to Edward Pick­er­ing, the dir­ect­or of her observatory.

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.
