To me, the latest H-alpha shots by experienced imagers like yourself and Paul are a discovery machine.
There is so much diffuse Ha on your image that it is going to be difficult to distinguish individual objects from the Ha background, in ultra-deep Ha exposures!
Actually, the main scientific interest of deep amateur Ha imaging might be the detection of highly unusual Ionized Gas structures far above the plane of the Milky Way, like ultra-faint outflows and supergiant Ha shells.

That's an interesting concept. Where would you point the scope to pick that area up? Above the Milky Way centre star area?
