East­ern Veil Neb­ula (NGC 6992)

Eastern Veil Nebula (NGC 6992) - Astrophotography Martin Rusterholz

NGC 6992 (Cald­well 33), togeth­er with NGC 6960 (Cald­well 34) and NGC 6995, is part of the Cygnus Loop, a rem­nant of a super­nova explo­sion about 15’000 years ago. As the shock­wave of this cos­mic blast col­lides with inter­stel­lar mater­i­al, it is ion­ized and is emit­ting light.

This image is a com­bin­a­tion of a deep broad­band image (RGB) with long exposed nar­row­band data (Ha and OIII), bring­ing out the fine fil­amets of the neb­u­las structure.

In memory of my friend Daniel.
