Anything made in America, gen 3 or newer, no worry about bloom out pointing at bright images, lights or the moon, they shut themselves off quick. I grew up around Night Vision, My dad built them for 27 years, for Varo, the originator, of the Starlight telescope. Now many good companies make them, and some crappy imports, companies like Raytheon, Litton, and ITT make good stuff, still expensive, and if you move up to thermal imagery 7,000 + dollars, but very cool. I was playing with the good stuff when I was 12, as the company allowed my dad to check them out or borrow them.
