Nikon Prostaff 5 20-60x82mm Spotting Scope.  Angled eyepiece.

This model is a bit larger than the 16-48x60mm version but the larger objective really helps in low light conditions.  And of course the higher maximum magnification brings viewed objects that much closer.  Magnification range allows easy sighting of individual bullet holes at 50m. Now with angled eyepiece allows for comfortable viewing with a smaller tripod, making packing easier.  Made in China.
