IC 1954 is a spiral galaxy in the southern constellation Horologium, about 47 million light-years away. It spans roughly 45,000 light-years and appears about 3.2 by 1.5 arc minutes from Earth, tilted at about 57 degrees. The galaxy has two large curling spiral arms with dark reddish dust lanes, and its disc is dotted with star-forming pink regions and blue star clusters. In the center lies a short bar with several bright knots, and a large cluster sits at its western end. The inner region contains a bright compact disk out to about 5 kiloparsecs. The total star formation rate is about 0.36 solar masses per year. IC 1954 is part of the IC 1954 group (LGG 93), along with IC 1933, IC 1959, NGC 1249 and NGC 1311, in the same galaxy cloud as the Dorado Group. It was discovered on October 14, 1898, independently by Robert Innes and DeLisle Stewart.
