Abell 2065
is a
large, dense and distant (some 1 billion light-years) galaxy cluster
in the constellation Corona Borealis, near Alphecca (alpha
CrB). For a smaller scope it is rather difficult target,
only the central giant elliptical galaxies of ~16m
are larger then 30", all others (more than 400) are smaller
and fainter. Still we can see here a lot of galaxies..
