Nice Infrared Sky in NatGeo's "Border Wars"

They use an infrred camera a lot in National Geographic Channel's
"Border Wars." I'm not sure if a lot of the points showing up are
actually insects. But it appears to give a brilliant starscape. Maybe
they should try this technique when they're filming movies and TV?
Instead of a purely computer-generated starscape, which I GUESS is
what most movies and TV shows would use, use infrared of the REAL sky
on-scene, onsite. Then maybe computer enhance that.
