Delisle Stewart discovered IC 1578 = D.S. 117 from a plate taken on 3 Nov 1898 at Harvard's Arequipa Station.
600/800mm - 24" (10/6/18): at 260x; IC 1578 and IC 1576 are a similar pair of extremely faint galaxies oriented SW to NE and separated by 3.3'. Both are very small, ~20" diameter, with a low surface brightness. The pair is located just 45' WNW of the center of NGC 253!
