There's an easy fix to this. Use a telescope. What telescopes do is
enlarge the amount of sky seen by the telescope's magnifying power.
Using a very low f ratio means your radiator can see a lot of black hole
in the sky, at a reasonable distance. Just focus the telescope on the
black hole and put the radiator on the focal point.
If anyone doesn't get this, I will go to the trouble of drawing an
diagram in ASCII (not my favorite thing....)
