This kind of system got me thinking of having 3 telescopes for simultaneous collection of Ha, OIII and SII data...maybe it is now slightly less impossible with recently released more affordable CMOS cameras...or even better, it would be very nice to have a 3-layered sensor with each layer collecting only one particular wavelength and at the same time being transparent to the rest of the incoming light...or reflecting the rest of incoming light to another sensor within the same camera...okay, where is my toolbox?

Suavi, maybe something like a dslr Bayer filter, because the individual pixels are optical filters for RGB, or probably better something like a Sony mirrorless transparent mirror(see pic) that reflects the light to a viewfinder, replace the viewfinder with a sensor and you're set
