Using the ISAAC instrument operated at 3.2 ms frame rate on a small array subwindow we could record light curves for 184 sources. Of these,about 20 were found to be binaries or multiples,the majority of which were previously unknown. Due to their small separations (up to less than 0.01 arcsec) and brightness ratios (up to 5 magnitude difference) these systems are challenging to be studied with any other present technique.We also report on several other starts found to be extended and with circumstellar emission.The large number of unresolved starts with upper limits on the angular diameter,collected from these observations as well as from similar previous papers,forms a useful catalog of calibrators for long baseline interferometers.
