This is what I already have in my finder....
Only this time I will use 5mm Ortho eyepiece and only one fiber (from edge to centre of the FOV).
Simulation/raytrace of round fibre in light path of the eyepiece-eye is also attached (light from one source is deflected by fibre, while nearby source enters eyepiece and eye.
I could even try to use this assembly as eyepiece projector, to image Procyon B.
Of course, if component B happens to be located in one of Airy discs, or visibility is poor, this will not help a lot...
