Wow! You surely didn't see the whole thing at once in this rig...
>At the opposite extreme I was able to see a part of NGC 2237 as a dim 
glow through my 80mm f/5 Orion ShortTube refractor equipped with a 26mm 
Tele Vue Ploessl (15x) and an Orion Ultrablock filter on board the MS 
Veendam during the 1998 solar eclipse cruise.  Of course, in the tropics 
the Rosette Nebula was much higher in the sky and it was really quite 
dark on the ship's upper forward deck.  I've also had some great views 
of the Rosette through a variety of instruments at the Winter Star 
Party.
These sound more typical I think.  The 80mm Shorttube is a great travel 
scope, eh? Good enough for decent views, cheap enough so it doesn't 
break your heart if it gets bumped around.
>At this year's Stellafane I had a wonderful view of the North American 
Nebula and the Pelican Nebula through Al Nagler's 85mm T V refractor, 
35mm Panoptic, and UHC filter.
That sounds right, too. I get just about the whole complex with my 
Shorttube and a 22 Panoptic, but what you just described sounds 
exquisite.
