Another of my favorite interacting galaxy pairs is the Whale and Calf galaxy. NGC 4631, the Whale shows it’s misshapen form even in a 4″ refractor. In fact my first observation of this pair was with a 4″ refractor. The fainter companion, NGC 4627, is easier to see with a larger telescope but with dark skies, it is doable with a 4″ refractor.
