Paul, I can contribute one observation with the 27-inch. Seeing was above average. I uses 419x.

NGC 6070B was separated without any problems but both cores were visible in one larger halo. I noted NGC 6070C brighter than B. So C was nearly visible with direct vision, while B was only averted vision.

The brightest HII region ([ZBF2015] NGC 6070 1/3) to the NE was clearly visible as a nonstellar spot. The fainter HII region ([ZBF2015] NGC 6070 2) to the SE was only suspected.

The spiral structure was not clearly visible. Some dark lanes indicated the spiral.
