On the basis of high resolution imaging and spectroscopy carried out using the European Southern Observatory (ESO) New Technology Telescope (NTT) during subarcsecond seeing conditions, we study the Large Magellanic Cloud (LMC) star HDE 269828 as well as another neighboring star cluster. We detect and classify 8 new O stars. High S/N ratio spectra of three known WN stars lying in this direction allow us to show that two of these Wolf-Rayet (WR) stars are multiple systems. In particular, the spectrum of Brey 65 varies from night to night. We argue that HDE 269828 is an evolved 'very massive star'. The interstellar absorption feature at 4430 A was detected in the spectra of several stars lying in the direction of HDE 269828. We study the correlation between the strength of the feature and the visual extinction and tentatively deduce a relationship.
