Deep-Sky Astro­photo­graphy

by Mar­tin Rusterholz

Cxielo Obser­vat­ory

CXIELO Obser­vat­ory is a remote-obser­vat­ory loc­ated in South­ern France and is a mem­ber of ROSA (Remote Obser­vat­or­ies South­ern Alps), foun­ded 2008 by Daniel Marquardt and Karel Teuwen. It is a rol­loff-roof obser­vat­ory host­ing an RCOS 14.5″ scope  and a Taka­hashi FSQ-106EDXIII car­ried by an ASA DDM85 mount. On both tele­scopes, a CCD cam­era with KAF-16803 sensor is used with Astro­don Gen2 LRGB and Ha (5nm), OIII (3nm) and SII (5nm) fil­ters. The dif­fer­ent focal length of the two teleso­pes res­ults in 40’x40’ and 3.5°x3.5° field of views.

Deep-Sky Astro­photo­graphy allows me to exper­i­ence the beauty of the sky. The pro­cessing of the images is like a med­it­a­tion for me – tak­ing the time to make the fine details of galax­ies and neb­u­lae vis­ible is a gift.

Deep-Sky Astro­photo­graphy

“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”.

There­fore Deep-Sky Astro­photo­graphy is my passion.

A few words about Cxielo

In sum­mer 2008, I was trav­el­ling for the first time to South­ern France at the place, where my friend Daniel Marquardt had built his remote obser­vat­ory. Help­ing him final­iz­ing the setup, the idea to build my own obser­vat­ory next to his dome came into my mind. Look­ing at the dark night­sky with the Milky­way touch­ing the hori­zon removed all my concerns.

Begin­ning 2009, the pre­par­a­tion of the ground and found­a­tion for my roll-off roof obe­ser­at­ory begun. Since March 2009, my obser­vat­ory is oper­a­tion­al and I am col­lect­ing photons whenev­er the sky is clear.

I am vis­it­ing the place mut­liple times a year for main­ten­ance of the install­a­tion and enyo­ing the nature and the night­sky. It became my second home.

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.
