Popis:

This photo is a reproduction from a combination of two CCD frames observed with the 3.5-m New Technology Telescope (NTT) and the ESO Multi-Mode Instrument (EMMI). The field covers an area of approx. 7.8 x 11.5 arcmin. In the lower part is seen the WLM dwarf galaxy , fully resolved into individual stars. A few background galaxies that are unrelated to WLM are also visible. At the distance of WLM , about 3 million light years, the field corresponds to a projected area of about 10,000 x 6,000 light years. The frames were observed in the near-infrared I-band and each exposure lasted about 45 minutes. The seeing was about 0.9 arcsec, and the faintest stars that are visible have an I-band magnitude of 24. In this reproduction, North is to the left and East is down.
