This is the H-HO-O bicolor combination. Melotte 15 is a very loose open cluster in the central regions of emission nebula IC 1805 (Heart Nebula) located about 7500 light years away. It is catalogued by the British-Belgian astronomer Philibert Jacques Melotte (1880-1961). This open cluster is about 1.5 million years young and contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.

Thank you for looking ...

When browsing through the hubble archives today I found this, previously not released, data of M57 from September 2011. I processed this data with the following result. This image shows the ring nebula with a detail never shown before anywhere in the world (as far as I know...).

In 1998 an image of this nebula was released by the Hubble team, based on WFC2 data (older instrument). This image was taken with the WFC3 instrument. A comparison can be seen here:

What I noticed is a strong motion of a star on the right hand side of the nebula which moved clearly in the 15 years between the two images:
