You don't need CCDs to track stars because you can use use a star tracker: https://en.wikipedia.org/wiki/Star_tracker   These were used in 50's & 60's missiles for navigation.

Here's some background on automated celestial navigation systems: https://ad.usno.navy.mil/forum/kaplan2.pdf    (Firefox gave me some security warning)  Probably used a Photo Multiplier tube on a sextant.

Being aerospace, it'll have all sorts of mechanical gew-gaws on machined aluminum structures all connected with those neatly laced wiring harnesses.  Be neat to have one to play with.

Cheers,

You could keep a telescope with a photo multiplier at the eyepiece pointed at a star and then measure the angles, you would need one for a few different stars. But what would you do if you loose tracking, how find back to the right star again? It seems like it would easily get lost.

This weapon could reach Sydney within 35 minutes of being launched from Moscow, thereby wiping out the EEVBLOG. Putin would not be so stupid. Even Trump first checked if the EEVBLOG would be affected prior to shutting down the US federal government.
