NGC 7447 does not exist. It appears as a nebula in the Markree Catalogue, but has not been seen again. Auwers, Tempel, and Burnham all failed to find it. Dreyer says that Burnham also noted a "F triple star a little np the place", but I do not see anything with about 10 arcmin that could be called a triple star.
I have not seen the entry in the Markree Catalogue, so do not know if it or the NGC entry might contain a typo. In any event, there is nothing at all near the place, not even a star bright enough to be included in the Markree list.

I examined this region very thoroughly on October 29th without finding anything in the least suggestive of a nebula of any kind. In or very near the catalogue place tehre is a 11-12th mag star, but there is nothing nebulous about it. A little n.p. the place there is a faint triple star, AB 200deg, 2'', AV 270deg, 10'', and perhaps with a small aperture this group might be mistaken for a nebula. The place was carefully examined again on a subsequent night, with similar results. This object certainly does not exist.
(Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads * DC.
