Description:
Very faint, small galaxy, with a nearly undeterminable shape: most of the time it appears spherical, but sometimes it turns into a triangle pointing to the East. Reacts fine to averted vision, rewarding me with a much larger size, but even with this method it is just barely visible. The 15.7m star on its North appears to be surrounded by faint fuzziness. New limiting magnitude record! Two of the stars on this sketch are no less than 15.8m faint! :D
