Your Nightfall starlight night vision scope is a professional specication night vision device
designed to provide enhanced viewing in all low light conditions including total darkness.
This night vision scope operates by amplifying existing light using an electro-optical system.
The Nightfall is a passive starlight device; it does not require any articial light source,
although an articial infrared light will greatly enhance the scope’s effectiveness in all facets
of operation. The Nightfall is constructed using an electro-optical intensifying tube contained
in a water-resistant composite housing and is rugged enough for extreme eld conditions.

• Visibility decreases or disappears.... Bright light sources may cause visibility to decrease or disappear and the image to
