This auction is for a really nice-performing University Optics (Nihon Seiko of Japan) 1.25-inch 32mm Konig. It will come with a perfect-fitting, aftermarket top dust cap.
**The last (2) photos are images seen through this Konig at 64x in my 1989 Celestron SP-C8. Classic to the unmodified Konig (before they were Mark II), the longer your focal length, the better those crisp views are as you near the peripherals. Crisp color, a feeling of depth, comfortable eye relief, and ease of positioning will follow this ocular in f/8 and slower systems. Yes, you can use this in your Coulter 8 f/4.5, Orion VX 102ED, or your Meade 10-inch f/6.3 LX200. The edges will go softer, but that central crispness will remain.
Central shadow will becoming faintly evident in the fast cats also.**
Against my standard tradition, this will be a simple listing, so I apologize in advance to those of you who love the long descriptions. I have to be at a couple functions here in Tacoma, WA this weekend and Jill and I leave tonight for the long drive; starting at 9:30pm. So, time is a crunchin' on me today.
This here is the generation of the UO Konigs after the "zebra" era and still long predates the Konig II era. It is almost equal to the 2-inch version with the exception of the slightly smaller exit aperture:
32mm 1.25-inch 32mm 2-inch
31.6mm EA 33.7mm EA
Both these models will exhibit the same field of view; right around 60-degrees on the dot.
Will accept virtually any 1.25-inch threaded filters from Japan, Taiwan, and Korea. Not all Chinese ones will thread to completion.
Weighs exactly 6.9 ounces.
This is a great-lasting ocular, and we could consider ALL UO Konigs to be collectible to a point because UO is long gone forever and this level of heavy-duty construction in a Japanese eyepiece is an era I don't see being revisited.
Overall, this Konig here is in great condition, but not excellent. The chrome barrel has a lovely, mirror-like reflection with some interruptions from barrel insertion marks; nothing bad as the photos show. Our favorite "NS" label is excellent; the "JAPAN" decal is fully legible, but definitely worn. The black body is even-black in color with no fade and no areas of paint shallowing. There are little contact marks and hairline scratches throughout, and we expect this in a responsibly, consistently used konig.
The etched characters are all legible, but some are not crisp. There is paint travel from the characters as "blotching" near their etch. The optics are definitely excellent for their age and (I think) as it sits. They are not mint. No internal dust, fungus, or haze to report. There are micro coating pits and really faint, partial hairlines to see off angle on the top element. The bottom element is fantastic. As those last photos will show, your images will be most pleasing at the focuser or diagonal. There is definitely no need to clean.
All nations welcome to bid.
