Though I might it I held it between me and the sky. Not tested that one. With full moon and little cloud I can see quite clearly at 200 meters or so. More with object silhoutted on higher ground but I cannot see in to any shadow. Every thing else is inbetween, a lot also depends on what you are looking for. I used to be a farmer, one night my Aberdeen Angus cattle broke out from their shed and even on a starlight night with a powerful lamp I could not see the animals owing to their glossy black coat. Unless they were looking at me, when their eyes reflected the light. I could also spot them if I lay down on the ground and silhoutted them against the night sky. On full snow cover on a full moon and a clear sky it is almost as good as daylight but again the shadows wil be impenetrable. One other thing, far away sources of bright light can ruin you night vision without contributing anything to illumination. SilhouettedSilhouetted</blockquote>
