Very large military eyepiece. Possibly made by Leitz in Midland,
Ontario Canada. Dimensions: 7" tall, 3.2" wide. 4lbs.
Has 2" adapter that comes off with set screw. Bayonette mount rubber
eyeguard as well.
F.l. is approx 31mm. FOV with 2" adapter is approx. 88 degrees.
Off axis images are not as good as a 31mm Nagler. Images are sharp
and have high contrast. Optics are multicoated, coatings and glass
excellent, no flaws. Outerhousing shows some scratches, not severe. Black anodized. Eye lens is dished, clear aperture is 1.1". Field lens clear aperture is 1-3/4".
Makes a very good wide field eyepiece if you can hack the weight.
I used on it on a 12" LX200.
$300 plus $10 shipping, insured.
