Abstract
We present the first results of an optical follow-up of X-ray bright
clusters of galaxies located between 
:
B and R
photometry as well as medium resolution spectroscopy of the galaxies.
The cluster studied here - A1300 -
is found to have a redshift of 0.3072 and a velocity dispersion of 1210 km/s,
based on 52 cluster members. Structures are observed in the galaxy
number counts
but the velocity histogramme shows no significant departure from a Gaussian distribution.
Key words: galaxies: clusters: individual: Abell 1300 / X-rays: galaxies / galaxies: redshifts
Based on observations collected at the Canada-France-Hawaii Telescope at Mauna Kea, Hawaii, U.S.A.
