This picture shows you a deep sky object bathed at 2 degrees southeast of gamma Serpentis Caput. Two small galaxies of UGC10169 in north and UGC10164 in south are paralleling with an interval of about 2 arc minutes, interacting gravitatively. Especially northern UGC10169 has a dimmed light lane stretched in north direction with a length of 2 arc minutes. It's considered that the lane is formed from inter-galactic matters spread by the interaction with a paired galaxy.
