This trio of galaxies is lying around the body of Draco, between theta and iota Dra. Those galaxies are NGC5985, NGC5982 and NGC5981 from east (left in the image) to west, respectively. They're paralleling proportionally with intervals of about 7 arc minutes, and they have different angle and/or shape each other, we can appreciate them with interest.
NGC5985 is classified in bared galaxy, NGC5982 is elliptical having no striking structures, and NGC5981 is considered a typical edge-on spiral. All galaxies have sizes with smaller than 5 arc minutes and visual brightness of dimmer than 12th magnitude. This image shows you these three galaxies in single flame looks like a brochure of sample galaxies.
