I've managed one so far from home in my 17.5", Henize 2-295 (see chart below). It was my first "discovery" using the blinking technique. Brilliant how neat through the EP you don't see anything. Flick the OIII filter in front of your eye and a tiny ball pops up out of nowhere! Bloody awesome.
I suspect that the boarder shown below of M7 is smaller than the actual limits of M7 really are. Other charts I've seen have NGC 6444 wholely within M7.
The GC NGC 6453 is just visible in an 8" under urban skies (
just). It makes for a nice wide field view with the core of M7, 6453 in the middle and 6444 on the other side.
The chart below is thanks to our mate NGCles. Ta Les.
