I keep meaning to build Nixie tube displays for our radio telescopes.
http://aro.as.arizona.edu/
They could display the following:
LST (Local sidereal time) and date
UTC time and date
Azimuth and elevation of the antenna
Declination and right ascension of same
Galactic coordinates
The coordinates would all have to be displayed down to a tenth of an arc
second, as that's the basic resolution of the antenna drive systems. The
Nixie displays in the movie The Dish for the Parkes antenna showed only
arc minutes.
I have a bucket load of B5870 calculator tubes, which would make the
most sense for this display, as it adds up to about 50 digits. Rack
mount, of course.

This clock uses 15, Z583M tubes. The tube boards for the 7 digit clock are
compatible, so several tubes can be used. ...
