NGC 6669 is most likely the asterism of six faint stars just north of Marth's position. This is of an appropriate size and combined magnitude that he would probably describe it as he did, "eF, pL."
Wolfgang followed the LEDA group's lead in assigning this number to a 16th magnitude galaxy with a 12th magnitude star superposed well off Marth's place. Had Marth seen this object, he would certainly have mentioned the star. I think that the galaxy is faint enough, however, that the star would mask it, even at the eyepiece of Lassell's 48-inch reflector.
The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy. Their coded description reads R,DIF,VRI*FIELD.
