yea that image intensifier is so cutting edge that the US military won't let it out of their sights! You got to swear on your Mumm's life not to let it fall into the wrong hands! i looked at 47 Tuc thru' an 18 inch dob, then the Tak 90 w/the image intensifier; well that little scope showed twice as many stars!
Then we did the same with Eta Carnia........
