Comment : | The galaxy NGC 4111 is one of many members of this galaxy group. 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. |

Comment : | 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. |
