NGC 6573 may be the Milky Way star cloud about 30 seconds following JH's position, but could also be the large scattered clump of clumps of stars right around his position. His description, from one night's observation at Slough, reads, "A cluster composed of 2 or 3 clusters of very small stars, and loose large ones. Perhaps an outlier of VIII. 31 [N6583]." He marks the RA with a plus/minus sign, so either grouping seems possible.
This is a candidate for observation at the eyepiece.
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NOCL S.
