Corwin's Notes
=====
NGC 730 is a star -- or perhaps two different stars. Bigourdan has
observations of this on three nights. The discovery observation on 7 Nov
1885, is only an estimate: +11 seconds and -4 arcmin from BD +5 328; there is
nothing at that position, though three stars in a line are south and west. On
4 Dec of the same year, he has a single micrometric measurement that falls
between the two eastern stars, though slightly closer to the eastern most.
Finally, on 30 Nov 1891, his two measurements point exactly at this eastern
most -- and brightest -- star of the three.
In any event, Bigourdan described the object on the three different nights as
1) having a "Doubtful aspect," 2) being "Strongly stellar; could be a star
13.4 accompanied by nebulosity," and 3) as "Pretty strongly stellar. Could
be a small nebula or a nebulous star; however, I'm not certain that there is
any nebulosity there." Since even he sounds pretty convinced that his object
is stellar, I'm not about to disagree!
