The Astrocompass (see pictures on www.usaf-nav-history.com ) was flown in USAF cargo planes such as the C-124 right up to the mid sexties (I have 3,000+ hours with this thing). It was and could be used on any celestial object listed in the current Ephemeries and Sight Reduction Tables (HO 249s at that time) to determine heading. Easiest was a sun reading as one got a strong shadow on it to go by. It was a good nav aid. It required a mount and a relatively smooth flight as one had to peek through its alignment forks to get the reading.
It is in the USAF Nav Manuals AFM 51-40s right into the 60s.
