I've got comparison pix showing red and blue sensitivity of: 

Kodak Ektachrome E100SW (gas-hypersensitized) 
Kodak Pro 400 (PPF-2) (gas-hypersensitized)
Kodak Pro 400 (PPF-2) (un-hypered)
Kodak Ektapress Multi-Speed (PJM-2) (un-hypered)
Fujicolor Super G 800 Plus (un-hypered).

They are at:

I've gotten good results on the California Nebula with the E100SW too, but
I think the California is not hydrogen-alpha emission.
