Description: At first I didn't believe what I'm seeing. It took a long time to be sure that NGC 4618 is really a some kind of donut. A main core and the brighter area on the south are quite easy to detect but bridges between them required averted vision, center is clearly darker. This has to be a really amazing object with larger scopes.
