NGC 6520 and Dust Cloud Barnard 86
This is a very interesting collection. You can see many, many yellow stars. There are also some blue stars. Which filters will help you find them?
Once you've found the blue stars, notice the shape of the blue stars and the shape of the dust clump. Coincidence? I don't think so. (OK I think they're related because my astronomer friends think they're related. I don't have any original ideas, I just tell you what others think. This image is sort of like plate tectonics. Since the puzzle pieces fit, they must have been together at one time.)
