Zeiss Jena APQ 100/640 - 4” f6.4 fluorite APO refractor. This telescope features superb color correction with pinpoint stars. Complete with optional factory rotatable 7X42 finder with its original caps, Astro-Physics compatible dovetail, Zeiss M68 helical focuser which accepts standard 2” diagonals, additional factory extension tube, attached lens hood with original felt-rimed metal lens cap, Zeiss Jena production test report (96.7 Strehl), rear desiccant plug, and zippered factory carrying case for storage and ease of transport (Zeiss ‘Traveler’!)
Blemish free OTA with crisp, unfaded Zeiss logo. Optics in excellent condition with a very small amount of dust, but no smudges, fungus or cleaning swirls to diminish visual performance. Helical focus of both OTA and finder provides the smooth tactile response expected of this fine classic instrument. Used sparingly, and stored in a smoke/pet free air-conditioned room.
