Number 17 of 150 made (1990 to 1991). Exquisitely figured objective as you expect from AP. Buttery smooth focuser, and it has the original rings (plus a custom made CF handle).
These are f/8.5. The view is VERY special - as good as Tak (though being from 1990, the contrast is not QUITE as good - maybe flock the dewshield?). I will include the original 2" / 1.25" visual back, as well as a modern replacement 2" back, plus a 50mm extension tube. Custom made dovetail shoe for Vixen-base finders too (nicely matches the focuser flange contour).
