NVTi 3000, three eyed
I shot this picture last winter during a demo in the ICW near Ft. Lauderdale. What you see (bigger here) is the ultra low light (.00015 lux!) output of a Night Vision Technologies (NVTi) 3000 Series pan and tilt cabin top triple camera. What you couldn’t see with your plain eye was that day marker, not to mention the water surface, trees and other shore details. Regular eyesight was mainly screwed up by the bright shore lights. 
Had it been pitch black—or had I been looking for something with a distinct temperature signature, like a man overboard—I could have switched over to the thermal camera. In daylight I might be spying around using the color cam with 220x(!) total zoom ability. Since all three cameras pan and tilt together, it’s very easy to try the different imaging technologies on a given target. This is expensive, but effective, technology.
