Description

This is the earlier image of M 51 (http://www.astrobin.com/177323/) annotated with galaxies. First a general annotated image was generated using the two-part script function in PixInsight. However that only found the two central galaxies of M 51 and several more.

Then I searched out the highest resolution images of that region of the sky and looked for any visual evidence of a galaxy. When one was found, I located the corresponding object in this image and marked it with the circle. In total there are 38 marked on the image. See if you can find more. There are obviously many as the Hubble Dark Field Image showed us all. These are just the ones I could identify with help.
