Galaxy groupings

Many will have seen the image of Stephens quintet from the JWT in IR:

Stephan's Quintet is a visual grouping of five galaxies of which form the first compact galaxy group ever discovered by Édouard Stephan in 1877 at the Marseille Observatory. It is in Pegasus, a little too far north for southern observers.

However there is numerous galaxy groups available to view, comprising groups of 3 or more. These were catalogued by Paul Hickson from Canada.
https://in-the-sky.org/data/catalogu...ickson&const=1

I have taken 40 of the brightest grouping visible at the latitude of Brisbane in the attached list. This list includes the well known trio in Leo and trio in Grus, but excludes the Markarian's Chain that forms part of the Virgo Cluster (more later).
