NGC 7202 is a star. John Herschel has only one observation of it, though he swept the area three times. Interestingly, he never saw more than three objects in this field in any sweep, and picked up only two in one sweep. Nevertheless, he entered the group as four nebulae in GC, in spite of his descriptions clearly stating that there were only three nebulae in the area. Still, this is not a compact group, with NGC 7201 and NGC 7204 being separated by 13.5 arcmin, so he probably realized that he could have easily missed one.
He stresses in a note that the RA is determined relative to NGC 7203 -- he puts it exactly one second of time preceding. The declination difference also puts N7202 exactly 3.0 arcmin south, so I suspect that this, too, is a relative determination, perhaps a simple estimated distance.
In any case, the object at the offset is a star; it matches John Herschel's description ("eF, S, star like") as well.― IC Notes by Harold Corwin
