You can't ask for much more than this pair of  interacting galaxies. They are easy to find and easily visible in a six inch scope. Located about 1/2^o to the northeast of Beta Cvn on a line drawn through Beta from Alpha Cvn, you couldn't ask for an easier place to find a galaxy. The larger and brighter NGC 4490 has a nearly stellar core and shows a strong sense of structure even in smaller scopes. With averted vision a faint outer envelope can be glimpsed, particular along the long axis. The smaller galaxy appears as a faint, irregular smudge.  Users of larger instruments should look for bright knots, particularly in the region between the two galaxies.
