also good for Chinese Exporters ?

Posted By Markus Ludes

Hi Herb,

Importers means, dealers in USA who importing chinese Optics. But hey I am in Germany, so selling to USA means I am a chinese (im-)exporter.

Does this name change now means I can speak here about products, announced by importers , who took deposits but not delivered due unknow reasons, which we carry and sell from stock most times ?

If that is allowed here , would be real nice.

there are so many new products available from china, where many US customers dont know , like new apos, apo spottingscopes, new widefield eyepieces etc.

thanks for clarification what I am as an exporter permited to speak here about

Kowa Highlä#nder Prominar 82 mm Fluorite prooved a

Posted By Markus Ludes

another night of observing

Kowa Highländer Prominar 82 mm Fluorite Binocular with
interchangable eyepieces. I modified some Meade 4.7 mm UWA to get 95
power. Oh Boy Epsilon Lyra Pair splittet into 2 clean douples. I
didn't know that this was possible in a binocular, but the Kowa, in
my opinion the worldbest large Binocular did it suprising easy.Also with that power it resolved easily this night M13 and showed surprising high end Jupiter imager with great Details

A friend told me that with old Meade UWA and old nagler Typ 2 , shortening them I get focuse, so I did it and it works superlativ good.

If you want the worldbest douplet Fluorite Bino 82 mm, the Highländer is your first and best choice

TMB/Zeiss 25 mm aspheric Ortho Info

Posted By Markus Ludes

Hi Guys,

this superb longer focallenght 3 -element aspheric orthos , optics made by CARL ZEISS was some time ago discontinued, due to small demand for starting a new production again.
However , since some more wanted to have this glas, we offered the original Zeiss Version with high eyeguard and same FOV for only $ 250 , available from stock.

Everything is Identical to the TMB/Zeiss , excapt the eyepiece housing and engraving. If you want one of such superb reviewed eyepiece, we accept orders

thanks for listening
