NGC 7493 is a star. Its micrometrically measured position and its description, from a single observation by Bigourdan in October 1886, clearly identifies it. Bigourdan was not so sure about it the second time he saw it: "Star 13.3 around which I suspect an exceedingly faint trace of nebulosity of which the existence is not certain."
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.
