This galaxy is rather small, about 5 x 5 arcminutes and is
another difficult target for a small scope. It is a weakly
barred galaxy with spiral arms emanating from the ends of the
bar. The infrared CCD frame clearly shows the bar a little
more clearly and shows the smooth spiral arms as outlined by
an old stellar population.
