Probably ,it's possible , somehow. However, it is not necessary to do something like that because you can achieved similar effect with little contrast and brightness tuning from the cockpit. It is one of the oldest "exploits" in Black shark wich aloves player to use guided missiles even during night. Personally , i don't use this possibility because i think it's very unrealistic . Optics installed on Shark is completely useless during dark night probably.However, this is not true in DCS:BS...
