IC 1396 in Cepheus

IC 1396 in Cepheus Astrophotography Martin Rusterholz

The large HII region IC 1396 in the con­stall­a­tion of Ceph­eus spans some 3 degrees of sum­mer sky. It is illu­mit­ated by a single massive O‑type super­gi­ant blue star, loc­ated at the cen­ter of the donut-shaped emmis­sion cloud.

Sevever­al comet­like struc­tures, known as bright rimmed glob­ules, form a loose an slowly espand­ing ring with­in IC 1396. Although sev­er­al of the comet­ary glob­ules are opticaly con­spicu­ous, the most prom­in­ent and well-stud­ied is IC 1396A (bot­tom), pop­ulary kown as the Ele­phant Trunk Neb­ula. A detailed image taken with longer focal­length can be found here.

Long OIII and Ha data have been com­bined with Lum to cre­ate an enhanced Lumin­ance, which then was blen­ded to a deep RGB to pre­serve the nat­ur­al col­ors. North is at 9 o’clock.

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.
