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 ~16^m are larger then 30", all others (more than 400) are smaller and fainter. Still we can see here a lot of galaxies..  This is latest version of the picture, after new data processing in 2025.
