"All the sextants (Astra, Cassens & Plath, Freiberger, Tamaya) today seem to
use exactly the same scopes. All these scopes seem to come from only one
manufacturer : Changzhou Celestaire Co. in China. Am I wrong ? What do you
think about the quality of these scopes ? Do you know other manufacturers
for sextant scopes today ?"

Celestaire owner Ken Gebhart, at the Navigation Weekend at Mystic Seaport
last month, was showing off the new model of the 7x35 sextant scope that
Celestaire's Chinese partners are just starting to manufacture. I had a look
through it and examined it up close, and it looks excellent. Ken explained
that they went to great lengths to get the mount exactly perpendicular to
the optic axis so that collimation is near perfect. Many other scopes in
this range have significant collimation problems.
