NGC
4038 is one of the Herschel 400 deep sky objects. It is also called
the "Ring Tail" galaxy. Although the center is fairly bright, the
outer regions of the spiral arms are very dim. You should just
be able to see the central area of the galaxy with a 6-inch scope and may
be able to glimpse the antenna with averted vision in a 10 inch or larger
scope, if viewing from a dark sky location. The "antenna" are
extensions of the spiral arms which just start to show in my image.
It is a classic example of what colliding galaxies can do. To see
the full extent of the "antenna" visit the sites I've provided links for.
