Just a crazy thought,
Given the limits of optical systems to present a brighter image to the pupil than what we can see unaided (other than for point sources like stars), our only options today are:
1) Magnify an image with, at best, the same surface brightness.
2) Do this with a binocular telescope so that at least each eye gets its own fully bright light path.
3) Use electronically assisted astronomy.
What if we were able to bring the image from several small refractors (say four 80mm refractors) to focus together. Would this allow (relatively) low magnification views with 4x the surface brightness we can get with one scope?
I’m not talking about bringing the scopes into coherent focus as in optical intereferometry systems as I’m not attempting to increase angular resolution. I’m only talking incoherent focus like in the Very Large Telescope:
if you add enough scopes, you could call the system “bug eye”!
I’m ignoring practical cost, size concerns right now. In the end, I expect a more practical solution is to rely on continued advancements in EEA: Use ever larger advanced CMOS sensors and high resolution microprojectors to present an enhanced virtual eyepiece view. But I thought I’d ask...
