Fast narrowband filters are much much much (pun intended) cheaper than additional 3 cameras, motorising additional 3 focusers, 3 more laptops/or super fast one to handle downloading 4 datasets at once etc etc
RASA was just an example of an alternative to an array of four small aperture f/5 refractors.
JA - it sounds like an interesting project - please keep us updated
