I've seen it 3 times with my 10x50 Orion UltraView binoculars - with 2 caveats...
Twice was from my house, Mag 5.5 skies, but I put my Orion UltraBlock Nebula filter between one of my eye's and the binoculars
I know it is probably considered cheating, but it works pretty well for
BIG emission stuff like the Helix, Veil, and North American Nebulas.
The third time I saw it was from a very nice site (Mag 6.5 skies) on a pristine night.
Now here is the pisser: I still don't care much for the Helix - it just isn't one of my favorites
Give the Nebula filter trick a try in your binos - should help.
