Description:
Nice round galaxy, that is a bit faint, but shows some brighter details (which are in fact parts of its spiral arms) around its tiny star-like core. A bit though object, but located in a relatively easy position with some brighter stars nearby. SQM reading: 21.15m/arcsec2, 5°C, extremely humid: by the time I finish this sketch, I can only barely see the Big Dipper anymore.
