The Abell Catalogue of galaxy clusters is a catalogue
of 4,073 galaxies compiled by George Ogden Abell (1927-1983).
Abell completed the catalogue in the early 1950's as part of his thesis
for his PhD. The Abell catalogue includes a northern and southern
sky survey. Abell and an assistant by the name of A.G. Wilson
poured through photographic plates from the Palomar Sky Survey using a
3.5x magnifying glass.
In order for a galaxy cluster to be included in Abell
catalogue, it had to satisfy four criteria. They are (1) richness,
(2) compactness, (3) distance, and (4) galactic-latitude. Richness
is further broken down into five categories depending on how many
galaxies are found in the cluster. Distance was further subdivided
into 7 groups based upon the magnitude of the 10th brightest galaxy.
Most of these deep sky objects (DSO) are dim and
really tough to view through most telescopes. You need really dark skies, a moderately large
telescope scope,
and a fair amount of patience to view these galaxy clusters.
