Corwin's Notes

===== NGC 764 may be the double star at 01 54 38.9, -16 18 22. There are no other candidates for it nearby, and Stone has left no sketch. His description is appropriate for the stars ("eF, vS, iR, gbM") but given his poor positions in the two Leander McCormick lists, its identity as N764 is nothing more than a guess. Curiously, the next object in Stone's list (No. 46) is not in the NGC at all. Its position is given by him as 01 54, -09 26 (1890), and is described as "m = 14.0, D = 0.2, R, gbMN". I do not see why Dreyer left it out of the NGC. Other of Stone's objects with similar descriptions are included, so the omission of this one is puzzling. In any event, there is nothing at all in the area that can be clearly identified with this list entry, so perhaps Dreyer had reason to suspect it that he has not told us. Also see my notes for this in the "notngc" files.
