The authors describe a multi-object fibre optic coupler they have developed for the Cassegrain focus of the Anglo-Australian telescope. The results of a test run on the southern cluster containing the dumb-bell galaxy IC 2082 are presented. Where comparisons with previous work can be made the radial velocities determined using the coupler show no signs of any systematic errors. The new results are briefly discussed in terms of earlier claims for galactic cannibalism in the cluster.
