| Comment : | Galaxy IC 2574, once called Eddington's Nebula because he didn't understand it was a galaxy when he discovered it in 1898. A weak galaxy together with a full Moon make it barely visible. On the full resolution image the galaxies M81 and M82 can be seen at upper right corner, they are much brighter. |
