The Zeiss 8x30B.  It isn't bright like the current ones.  I wish it could be coated with the modern stuff.  I picked up one that had some slight haze to it.  The prisms had some kind of deposit on them, but not fungus.  I have learned how to disassemble optics over the years for cleaning.  When one "breaks into" an older Zeiss. the precision of everything becomes readily apparent.  I discovered with the the lids of the Zeiss monocular a flat neoprene gasket unlike any other which really seals things nicely.  The prism recesses are so precise that after removing the individual prisms for cleaning, they can be reset easily.  Of course a monocular with slight prism misalignment won't be the problem for colimation that a binocular would present.  I do not recommend tearing into a quality piece of optics for cleaning unless one is prepared with the correct tools and know how.  I am self taught and have made a number of mistakes (costly ones) until I gained enough experience to know my limits.  But that is part of the fun of working with optics.  John</p></blockquote><p></p>
