     HD 269858 is the southeastern component of a 3" pair; the 2MASS
position is preferred over the one by Breysacher:

HD 269858 = RMC 127:  5 36 43.71 -69 29 47.5  (J2000)

The northwestern component is about V = 12.1, and is a B0Ia supergiant.
RMC 128 is about 19" southeast of RMC 127.
     A detailed chart with photometry and spectral types is given
by Heydari-Malayeri et al in 2003A&A...400..923H.
