Nikon Fieldscope ED50 50mm Angled with USED 20x Eyepiece

Angled scope body is brand new, directly from Nikon Canada, with all original packing material. 20x wide-field eyepiece is used, but in excellent condition - looks new. No original box for the eyepiece.

The Nikon 50mm Fieldscope is your ultimate travel companion. The compactness and extreme light weight offer no excuse to leave it behind, but it doesn't stop there... Nikon added their best optics, so every outting into the wilderness will be experienced with the utmost clarity.

This is the least expensive high-quality ED scope we've been able to find. Experience nature, the Nikon way.
