The gas clouds in the center of the image bear the unofficial name spider nebula. Officially cataloged as IC 417, the complex is located approximately 7,500 light years away from our solar system in the direction of the constellation Auriga. Also in the picture is the small nebula NGC 1931, suitable for the spider, also referred to as a fly. Below left another shock front, I personally would call it "ant" :-)


The image is a cooperation project with Frank Iwaszkiewicz from Eggersdorf near Berlin, who added 8 hour H-Alpha and 4 hrs SII as well as OIII with his 10 "ONTC Newton and an Atik 383L + camera.

This is the version with Franks newtonian image field:



Here you can see the local connection with the well-known tadpole nebula:


And this is a version in HaRGB:
