North America Nebula
This is really an odd object: The North American Nebula is easily visible to the unaided eye as a bright patch near Deneb almost whenever the Milky way is visible. Yet, the larger the scope, the harder it is to see see NGC7000! The easiest way to see the North America Nebula with optical aid is to use binoculars in a dark sky. Yes, the "Gulf of Mexico" region is relatively easy to see in a scope, but it still has very low surface brightness.

North America Nebula
This is a spectacular summer object which is most friendly to four and five inch short focal length apertures. It certainly is not an easy naked eye object in my part of the world. It is very "friendly" to OIII, meaning the OIII filter brings out a great deal of detail not available in white light. And it is becaue of the OIII that one is better off with 102mm than 80mm aperture--it can be done in binoculars etc., but to get the "power" through an OIII you're better off with 102mm or so. You need at least three, and probably four degree field of view to take it in and see the "continental" effect. The original post is right: the bigger your scope the less interesting it looks.
