SNR Can­did­ate G70.5+1.9 in Cygnus

G70.5+1.9 is a can­did­ate super­nova rem­nant dis­covered in 2009. It meas­ures approx­im­ately 5x3 arcminutes and its beau­ti­ful struc­ture con­sists of a series of inter­lock­ing elong­ated and curved fil­a­ments with its south­ern rim being the bright­est part. OIII in par­tic­u­lar reveals an impress­ive tail struc­ture with a length of 8 arcminutes that extends to the left. The pub­lic­a­tion about the dis­cov­ery can be found here.

Fur­ther to the south is the Sh2-100 emis­sion neb­ula com­plex (left) and Sh2-99 (right).

The image is a com­bin­a­tion of long exposed nar­row­band data (Ha, OIII) with RGB data. 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.
