Telescope Reviews: N Amer neb ?

I was out at a dark site this weekend - showed off a bunch of goodies to some friends & neighbors Thurs Nite but had superb sky to myself on Fri. After playing thru Sag & Scutum & Sagita & Delphinus, I realized that NA neb was winking naked eye. It looked fine thru my 11x56 broadband binocs. Pelican showed decent too. I sniffed pretty well at it thru the 30mm (40X) on the DOB. I added my dgm-npb filter to the 21mm and was able to track distinct variations throughout that nebulous region. I hadnt realized this narrowband could enhance the NA. Is this generally true? or only in dark skies? General emissions for NA=???
