This picture shows you two compact galaxies positioned at 3.5 degrees SSW from iota Draconis. Left one is NGC5908 and right one has a number of NGC5905. NGC5905 is a typical bared galaxy, has a span of about 4 arc minutes and 12.6th magnitude in brightness. The galaxy has a round and bright central region and dimmed two arms are stretching in east and west directions. We can hardly recognize the arms, looks like an elliptical galaxy. NGC5908 is an edge-on spiral with a long axis of about 3.3 arc minutes and a brightness of 13th magnitude, a dark lane is detectable in this picture.
