Nikon MEP 20-60 Zoom Eyepiece for Monarch ED 82/65 Spotting Scope

The MEP 20-60 zoom eyepiece came with my new Monarch 82 ED scope but has never been used and is still in like new condition. The eyepiece has a F type bayonet and fits the Nikon Monarch 82 ED/ 65 ED spotting scopes only, not the older field scopes with screw mounts. However, I was able to adapt it to an EDG 85VR scope. Surprisingly it is nearly perfect on the EDG.

On the monarch, it shows slight CA on the edges of the view, but on the EDG, CA is nonexistent.
