This
            is the first Deep Sky test shot with the newly recoated primary
            and secondary mirrors for the 12.5". Seeing was horrible,
            so the stars are not quite pinpoints, but indeed the colors are
            rich as ever and the sharpness across the field is good. This
            is 30 mins total RGB data only.
