I have to amend my answer to Francisco because I forgot to consider narrow band imaging, which is a rather dumb thing to do considering how popular it has become. It must be because I never did and don't intend to do NB in the foreseeable future.
When we put a NB filter in the light path, we severely cut down the photon flux and we really get into shot noise dominated territory. And that is where aperture really matters (as Peter so nicely pointed out). Of course RGB is subject to the same laws of physics but NB is really pushing the limits.
So, Francisco if your game is NB imaging then you will have a much more capable setup if you fork out the money for the scaled up one.
