Hickson 86, A Compact Group of 4 Galaxies
Also: Galaxy ESO 461-5

A 10 minute exposure taken with ST-9E CCD camera thru Kopernik's 20 inch telescope. The scope was focal reduced to F/4. The field of view is about 16x16 arc minutes, with North at the top..

Quote from Paul Hickson's Atlas of Compact Groups of Galaxies:

"This is a relatively loose quartet of (elliptical) type galaxies. Another galaxy (ESO 461-5) of comparable brightness can be found to the west, and may be related to the group."

These five elliptical galaxies are in Sagittarius. Based on their red shift, a rough distance estimate for Hickson 86 is 315 million light years.
