NGC 6499 is a close double star. Discovered by Marth, he marked it "verified" in his list, so he saw it as nebulous at least twice. When the object was photographed at Heidelberg and Lick, the observers there found only a double star without nebulosity. That is how it appears today on the Palomar Surveys. Another faint star and 2-3 very faint stars just to the west may have given the appearance of nebulosity at the eyepiece.
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads ** DC.
