I'm looking at a set of Russian NV Binoculars. I'm told they are second generation. They take 2 AA batteries, and are 2.5 x 42.
My questions are;
When in use, there seems to be a sparkly effect in the center of both optics. This effect is visible while the binocs are on, as well as after they have been turned off(the tubes remain illuminated for about 5 minutes AFTER the unit is switched off). Is this sparkly effect normal?
Also, the unit has an illuminator attached above the binocs. I thought it was supposed to be infra-red, yet when standind down range you can see a faint red glow. It is not as bright as a standard LED, yet it is easily discernable. Does this sound normal?
