NGC 2259

Region near the cone nebula.

This picture shows a region near the much brighter cone nebula. In the lower left corner you can see the first parts of the so-called "fox fur".

I could not find a catalogue entry for the dark nebula region projecting into the picture in a wedge shape as well as for the light blue shining emission nebula.

The open star cluster NGC 2259 lies in the direction of the constellation Monoceros and is about 12,000 light years away from our solar system. He is several hundred million years old, which may sound old, but is actually a relatively young age. For comparison: Our sun is more than 4.5 billion years old.

The image was created in the Hubble color palette, where the stars were inserted from RGB images, representing real star colors. As a variant here is an additional bicolor version, in which only H-Alpha and OIII were processed together with the RGB. This results in a red-heavy colour impression, which takes into account the H-alpha predominant in the area:
