NGC474 taken by David Ault of Georgetown on 10/24/2014 with a ATIK 314E camera through a Stellarvue SVR90T w/ flattener. Mount: Losmandy G11 w/ OPWB Exposure: 66, 10 minute exposures taken over 3 nights – 10/20, 10/23 & 10/24 Software: Sequence Generator Pro, PHD2, PixInsight NGC474 is an elliptical galaxy about 100 Mly away which has tidal tails creating an interesting shell around itself. Visually it appears that this might be due to interactions with NGC470 and NGC476, both in the field of view, but the source of the tails is currently...
