Description

A lovely galaxy triplet in Draco, showing different galaxy types. NGC 5981 is an edge on spiral, 5982 is an elliptical galaxy, while NGC 5985 is a near face on galaxy.

Interestingly, you can make out a couple of outer shells in the elliptical galaxy, signs of gravitational interaction - I wasn't entirely sure they were real, but are also there in APOD photos. Finally, if you look hard, the background around the galaxies is slightly brighter - there has been an envelope of hydrogen detected in the CLOGS study surrounding these galaxies - not sure if its that, or just poor flat fielding!
