Maybe related, depending on how close the light from the far target is to tangent near the lensing star, there is also an atmosphere around the star that is emissive. I was thinking that's mostly noise, but maybe it's accelerated enough to shift its spectrum and serve some purpose in measuring the lensing strength? But either way, would need to characterize it enough to remove it from signal.
Heya, I'm really inspired by the idea. I propose we work it up into a paper, On the Existence (or not) of a Multiple Gravitational Lens Telescope.
I've created a project under Celestiary since I think we can use the code there to do the search on the Celestia star database and also do simulations.
