Hi:
After seeing a reference to "Splitting the Second" by Tony Jones on
Tom's web page I read it and found that the Photographic Zenith
Telescope was replaced by the "Danjon Astrolabe". But Google provides
almost no information about it. A patent search has turned up a number
of optical systems, mostly for spacecraft, that use star separation for
navigation, and if used at a know location on the earth could be used
for timing. For these see my Stellar Time Keeping web page:

Does anyone know how a "Danjon Astrolabe" works?
Have Fun,
Brooke Clarke
