Went out tonight and with a limiting magnitude of about +5.2 visually at midnight (it got a little darker by 1:00 a.m. local time, maybe about +5.5 mag. overhead) I observed NGC6028 as a slightly oval patch of light, extended E/W, suspected a faint star south of the core at 295x, but couldn't hold it. No ring... I suspect the minimum aperture to observe the ring might be 48-inches (ha,ha). To give you an idea of the sky conditions, I observed NGC5991, IC4553 and IC4554, NGC5975 and MCG+4-37-21, UGC9958, UGC10020 and NGC5972... tried (not too hard) for NGC5977 but was unsuccessful.
