It's problem is...
Form the direction 1, the image doubled.
If I rotate binoviewer then two images rotate each other.
Form the direction 2, I can merge image easily..
Far sight is instant near takes few seconds...about 0.5 sec.
I disassembled once(only discover labled 3 part).
The prizm was fixed with glue and it was very hard so I can't move it, so I think it didn't do any collimation problems.
Is my binoviewer needs collimation?
How can I do that?
The prizms are all fixed.
Is anyone disassembled this binoviewer before?
