VDB 152 and Barnard 175

(click image for full resolution)

The reddish nebula in this image is Barnard 175 - 1,400 light years away from earth. On top is the reflection nebula VDB 152. Interestingly, the star that causes the reflection is not from the nebula but is just passing through (it's velocity is very different from the nebula's velocity).

Zooming into the reflection nebula:

You can (barely) see two red lines. These are the remnants of a supernova explosion. I should take more Ha data for this image to make these better visible.
