There is nothing at Bigourdan's position, which is about six arcmin north-northwest of NGC 5541. He has only one measurement of the position, referred to AGK1 (Bonn) 9350 = SAO 064040. His table has the RA of this star 10 seconds too large, but that does not help us find his nebula.

In the immediate area, there are no galaxies at similar offsets from other stars of similar brightness. I suspect Bigourdan misidentified his comparison star, but with no candidates in the area, this remains only a suspicion.

Wolfgang originally put the IC number on MCG+07-29-058, but this is 3 arcmin off of Bigourdan's position and does not match his measured position angle and distance at all. In his latest list, Wolfgang has given a nominal position and listed the object as "Not found."

A check of Bigourdan's supplemental observations and his errata lists turned up no more information on this object, so this observation will probably remain a mystery. Another "fausse image", perhaps?
