Very nice cluster that is well populated with faint little stars that are very identical in both brightness and colour (bluish gray), with maybe one or two brighter stars in the middle. I can notice several star paths in the cluster. Very difficult to sketch.
SQM reading: 21.06m/arcsec2, -2°C, very strong wind.
