Dear IIS team,
Very rare, very very good Nikon ED Glass optics - when Nikon actually IMHO made better optics than even Canon - but these days Canon make better optics, as attested to by Takahashi's telescopes which have always used Canon glass
Expensive yes, rare ? Very much so.
Collectors in Europe and the US would find this quite attractive, the price is somewhat high but this reflects the rarity of this offer.
Clear skies.
