the field of vision is too small for any useful viewing.
the field of view is fine, and you can see a ton of detail within a reasonable range.
good illumination and nice balance between magnification, field of view, and use w/o a tripod.
this is another good scope by a well known brand - night owl, and should work well for most.
within a city you will hardly find a spot dark enough to fully appreciate the scope, but in the country side at night this thing is incredible.
i have been using this scope on the beach at night to monitor sea turtle nesting.
personally i think this night vision scope performs great.
even so, the effective viewing angle is wide enough for comfortable viewing.
the unit is also worthless for viewing anything closer then 10 feet.
if you really are going to invest in a night vision scope, you may as well go with a more expensive model.
i wanted something good enough to enable clear, comfortable viewing - even in the darkest light-conditions with a powerful lens at a low, low price.
i just received and used this night owl nightvision model "nocx3".this product worked great.i had 3/4 of a moon.location was a wooded lake area 1:30am.i could see clearly at least 300 ft
i use an ir-scope at work that cost close to a $1000, but this russian beauty is comparable to that in quality costing only a fraction of that.
with the night owl night vision scope, you won't be lonley at night anymore!
i figured the national geographic brand ought to be a good product, and wasn't disappointed.we used it to view the wildlife in our backyard woods at night, and it was really neat!
it is a good night vision scope.
you get a green low-light view of the world thru a monocular not the glow-in-the-dark ir effect you may have seen on tv in police chases.
the later generations do allow viewing at longer distances and at lower ambient light levels however.
as others have mentioned the center of the viewing area is in focus but the outter ring is blurred but not horribly so.
unit had a very large defect in the field of view.
this scope would have a better score by me if it would work properly.
at night i'm able to view animals at great distances in the field behind my house.
