Martin, about how bright would you say the ZL was? About as bright as the Milky Way in Cygnus?

The reason I ask is that I think I saw it from home this evening - difficult to be sure because of light interference but the shape & position seemed to be right - OTOH the unless the ZL is variable in brightness (why?) then I don't understand why I haven't seen it before.

Best way to make out the shape, by eye, is to scan rapidly across the area so you get a sense of contrast - the eye does a sort of "flat subtraction" against the scene if you stare in one place, making the subtle contrast gradients harder to see.
