Corwin's Notes

===== NGC 7058. There is nothing at JH's position, but just one minute of time to the east is a clump of about a dozen stars that matches his description. All he has to say of this object is, "The chief star of a coarse, poor cluster." The brightest star in this 5 arcmin by 3 arcmin clump is SAO 33352; this may be the one that JH measured. Since I don't see another reasonable candidate in the area, I'm taking this as his cluster. However, I would suggest that a more thorough search at reasonable digit offsets may be called for. ----- Examining the sweep (number 207 on 8 Sept 1829), I see that JH has a note, "A very odd break in the RA between two almost contiguous stars." It's not clear to me which two stars he's referring to -- there are several in the sweep around the time he picked up this cluster. However, the fact that he saw a problem suggests that the idea of a one minute error in his RA is a reasonable suggestion. So, I am going to stick with the idea for now.

Steve's Notes

===== NGC 7058 17.5" (8/25/95): bright, scattered group including mag 7.9 SAO 33352 and four other mag 9.5-10 stars in a 4'-5' region forming the borders of the group. There are roughly two dozen stars mag 13-14.5 in the immediate vicinity but the density of the fainter stars is actually lower than other rich regions in the same low power field. So, only distinguishable because of the grouping of brighter stars which may form a physical group. Listed as nonexistent in RNGC.
