Description: One of the most difficult objects which I have ever seen. The brightest nebula consists of PGC 54804 (A, 15.0 mag) and PGC 54803 (B, 15.7 mag), I wasn't able to separate them. Two very faint ''fuzzy stars'' on east are PGC 54824 (D, 16.5 mag) and PGC 54827 (C, 16.5 mag). They were visible less than 10% of time with averted vision. Other members were too faint for me.
