Corwin's Notes

===== NGC 6230 is the brightest galaxy in a small group. There is another somewhat fainter galaxy just an arcminute west. Swift's position is actually closer to the fainter object, but his description reads "eeeF, pS, R; bet. a distant B * f. and a distant F * p; ee diff." The brighter galaxy is very nearly exactly between the two stars, while the fainter one is noticeably closer to the fainter star to the west. Furthermore, the brighter galaxy has a star superposed about 15 arcseconds southeast of the nucleus; this would have enhanced the image in Swift's large-field eyepiece. Given all of this, Swift's object is almost certainly the brighter galaxy, so that is the one I've taken.

Steve's Notes

===== NGC 6230 24" (6/12/15): at 375x; faint, small, round, 18" diameter. A mag 14.5 star is at the southeast edge. A wide pair of mag 14.1/14.9 stars is less than 1' NW. Located 5' W of mag 9 HD 152087. Forms a close pair with PGC 214543 1' W. The companion (identified in NED as NGC 6104 NED01) appeared very faint to faint, small, round, 15" diameter, low surface brightness but not difficult. The components have a similar redshift with a light-travel time of ~430 million years, though there is no obvious evidence of interaction. 17.5" (7/1/89): very faint, extremely small, round. A mag 15 star is off the south edge. NGC 6234 lies 22' SE.
