Observation Notes:<\/b><\/p>\n

After tracking down NGC 3090, I headed for this beautiful pair. Under less than ideal conditions, general elongation and structure were difficult to discern. The view was still stunning as the two galaxies fit nicely in the 24 arcminute wide view. Eric Graff observed and sketched<\/a> this pair about the same time, but in a wider field.<\/p>\n
