Description

M104 in southern Virgo is well known by its common name sombrero, but for me this name is not apt as the usual central cone of this mexican speciality is missing. Readers of Perry Rhodan - world's most extensive science fiction epos - know it by the name Gruelfin, so it may be a good alternative (we could even discuss if Perry Rhodan readers outnumber astronomers).

As this standard candle is so well known, I don't lose too muich words - just don't miss the full field and search for faint but big background galaxies!
The Namibian sky allows to catch them even by the short exposure time.
