NGC 4490 and NGC 4485

For Telescopes 5" or greater

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 1/2o 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.
