Description:
Large, spectacular galaxy. Perfectly round, shows no sign of a star-like core, although its central region is a bit brighter. It's very faint, but I can observe some brighter details around the core. By checking out photographs today, it's now obvious that these spots are parts of a spiral structure. SQM reading: 21.20m/arcsec2, 5°C, very humid.
