Today I'm adding to my space dust collection with Sharpless 73, which is mistakenly included in the Sharpless catalog as an emission nebula. It is in the constellation Hercules and is simply a molecular cloud. A big'un. Sh2-73 is one of the closest clouds to the solar system, being just 200 parsecs away (about 650 light-years). It is located at a very high galactic latitude and does not appear associated with any bright star, nor are star-forming phenomena active in it. Ashes to ashes and dust to dust. If you look carefully, you'll see that this image also contains several galaxies.
