I used a 13 mm Baader Hyperion which gave 280x with a 15 arc-minute field. M27 fills the whole field with this combination and the view is unbelievable! The familiar dumbbell-shape is gone and the major axis has been turned 90 degrees compared the view of small telescope. Central area is very bright and it's difficult to detach faint structures inside the glow. O-III filter is the right aid for this object. Everything becomes much sharper. It's almost impossible to sketch all small details which are in view with the averted vision. The coolest details are in the "wings", that contain several fibrous structures.
