What does it take to see IC1396 visually?

IC 1396 is a large gaseous nebula in Cepheus, associated with a large, loose cluster of stars. I have been observing a couple of double stars in it, the quadruplet (triplet in small scopes)Struve 2816 being located in the very centre of the nebula.

However, I can not see any sign of nebulosity there with my 8-inch f/6. O-III does not help, and since I have no UHC-filter I can't tell if this will make the nebula visible.

I suspect that the ideal for this object is a smaller widefield scope (4-inch f/5 ???). Have anyone ever seen this nebula? Will UHC help? How do large Dobs perform?
