NGC 5981/82/85 (Draco Triplet)

Introduction | Map | My Own Photos | My Own Observations | References

On this page I collect my observations of the galaxies NGC 5981 (spiral), NGC 5982 (elliptical), and NGC 5985 (barred spiral) (Draco triplet) in the constellation Draco.

 

Introduction

The galaxies NGC 5981 (edge-on spiral), NGC 5982 (elliptical), and NGC 5985 (barred spiral) in the constellation Draco form the Draco triplet (galaxy trio Holm 719 or KTG 64).

In the Vespera Pro mosaic, there also appear the lenticular galaxy NGC 5976 and the spiral galaxy NGC 5989. Both galaxies are members of the NGC 5982 group, which also includes NGC 5981, NGC 5985 and NGC 5987 in addition to NGC 5892.
