Small field near centre of Omega Centauri (NTT)

Small field near centre of Omega Centauri (NTT). This false-colour photo has been reproduced directly from the best CCD frame obtained with the ESO New Techonology Telescope during the night of ``first light'' on March 23, 1989. It shows a field near the centre of the bright southern globular cluster Omega Centauri; the size is approximately square arcsecond. The atmospheric ``seeing'' was extremely good, and the diameter of the stellar images (at half of the maximum intensity) is measured as 0.33 arcseconds. The exposure lasted 10 seconds. North is up and East is to the left. (ESO Press Release eso8904; Colour)
