The Sagittarius dwarf irregular galaxy (SagDIG, ESO 594-4) lies some 3.5 million light-years (1.1 Megaparsecs) from us. Background galaxies (reddish/brown extended objects with spiral arms and halos) are located even further beyond SagDIG at several tens of millions parsecs away. This dwarf irregular galaxy was observed by the Advanced Camera for Surveys on-board the Hubble Space Telescope on 18 August 2003. Fifty-minute exposures were taken in blue, green and red filters.
