Dear Modris,

You did not tell me in what year was SNO-T manufactured, and this may be relevant.
Early 90s is the time of collapse of Soviet Union, the time when all 
production there was in a complete disarray.

Another shocking feature noticed by Bill Morris was that on most of them (all 
of them?), the shades assembly is installed up side down:-)
This does not affect the performance, but it is really shocking. See his blog 
on SNO-T. He gives a detailed instruction how to install it correctly.


BTW, my night scope of the sextant made in 1990 also had a defect, but different one. It was fixed on
Freiberger factory where I brought my sextant for certification. They 
certified it as "error free for practical purposes",
but this essentially applies to the arc, drum and pivot.

Generally, I share Bill's opinion, though my experience with various sextants is much smaller than his.
(It is especially good for the Lunars, due to its long arc, small weight and good inverting scope).
 
But the box and the night scope are not the best things in it:-)

And the quality may depend on the year of manufacturing.

Alex.
