I found this in a local junk shop for the equivalent of US$30. One of those 'Oh Wow' moments.
These are approx. 20 year old Japanese made 'Emsom' binoculars.
The optics are in mint condition the body is in good condition.
Water proof and with a 3 degree FOV. They are I.F. with a 20 mm ER and soft rubber eye cups.
They weigh a light 840 grams /29 oz. The lens are a green / magenta hue.
They are perfectly collimated. Clear aperture is a full 50 mm via the flash light test.
How do they perform ? very well. The image is primarily flat and sharp to edge, stars are almost pinpoint and yes for 20x50's the image is actually fairly bright.
The make just lovely 'grap and go' binos. Orion’s nebula show up nicely and Jupiter shows a nice round orb with a hint of a band visible. CA is visible but not distracting. They are just so great to use as a day time spotting bino scope and as quick look night scope. Plus they look cute. [My wifes comments].
Yes they are keepers.
