Omcon Orthoscopics 5 eyepiece set, parfocal (w/very minor refocusing), Japan, bought in 1987. Cone shape tops like UO's, engraved lettering, multi-coatings (color greenish-blue) and 43-45* AFOV. One owner, well cared for and stored in foam eyepiece case. Glass in all 5 in excellent condition. All caps but one, and 2 boxes missing. Here are the focal lengths and barrel descriptions:
25mm; near mint
18mm; minor set screw marks and tiny scratches on chrome.
12.5; (same as 18mm)
9mm; small scrape on barrel and knurled grip.
6mm; (same as 18mm)

I compared the 12.5mm to an older UO 12.5mm and the image sharpness and contrast were virtually identical. I have not compared any of the others. Comfortable to use with great contrast, sharpness and nice black sky background. I will not break up the set. $195 shipped, CONUS. PayPal, money order or cashiers check, please. Thanks for looking.
