Hi Denis

Do you mind sharing more information about the "world sharpest" Leica binoviewer? Thanks!

Howard

Hi Denis

 

How about the comparison result with Leica and Zeiss big bino? I don't think most people would have the opportunity to compare them.

 

Thanks 

Howard

Sharpest Leica produce bit more sharpness, bit more contrast, bit less scatter.
But BIG Zeiss is more than excellent, and top of them Zeiss prism line.

Hi Dennis

Will you perhaps review the Linear binoviewer someday?

Hi Timmo,

 

no plans at all, for now.

 

These binoviewers have 16 (sixteen) air-to-glass-surfaces (definetly too complex design), while common binoviewers have them 7 (seven) only, while best ones like BIG Zeiss have 5 (five), Sharpest Lecia and Zeiss (with mirrors), 6 (six).

The same "corrected" binoviewer is offered by TS.

 

Remember that these interesting binoviewers contain inversion optics and zero power, glass path correction.

 

These would normally have to be added as completely separate and quite expensive components.

With the very grave disadvantage of hugely increased power and often greatly increased extra length/overhang.

 

The downside with the corrected binoviewers is their very small clear aperture.

This will limit their usefulness with the low power eyepieces they claim to support.

Correct.

I think I read here that the clear aperture is a paltry 17mm.

Procyon, we all warmly hope Croatia win smile.gif
I wish I could do such prices, but my profit is already VERY LOW, after I buy hand selected binoviewers, pay very expensive CNC machining custom made adapters, buying new eyepiece holders, pay shipping for them, CNC machining eyepiece holders, CNC machining in Supercharge Service process (very complex work of many different steps, machining, blackening........), I also add/buy new Baader Quick Changer, new Baader T2 to 1.25" adapter, spending couple of weeks untill I finish just 1 unit (including complex collimation process), pay ship to end user.....
So you see smile.gif
