At 168 (15 mm Panoptic) with OIII-filter obvious sight. Round, <1' diameter with a darker middle, sometimes some mottling visible? (not sure).
At 360x (7 mm Nagler) without filter still ringstructure visible.
Ring is brighter at the north edge, looks at moments of good seeing
like a lens, that seem to ride on the ring. Lens not visible with filter. 
This must be the famous galaxy. Wow, what a nice constelation!
