All of that with just one camera so a cheaper and simpler system. The only compromise I can think of would be a smaller field of view with RASA.

You will need fast narrowband filters at f2 and those are not cheap. But then again the RASA is over priced in my opinion, given the cost of used Edge 8" which are Faststar ready.
