Click on the image and get a new image in full resolution, how many galaxies can you find ?
The soft weak rings you see is a rest of dust blobs I have removed during the image processing. |

One way to get to know which objects there are in the image is to use a plate solver. I used
Astrometry.net to get this image with information.
If you look carefully in the full resolution image you will find more galaxies. |
