The other cameras you mentioned would need to be modified for hydrogen alpha response. So, while you could get a new or second hand 5D Mark II, you would still need to modify it, thereby ruining its daylight spectral response as well as autofocus system.

The camera is aimed specifically at astrophotographers. Particularly those who aren't interested in, or can't afford a CCD.

Maybe I already own a CCD, 60D for terrestrial photos; and can't reason for this the mid point at that price.
