    Here are links to two youtube videos showing astrocompasses being used in flight. The first one is me using it in a Cessna 162 and the second is in a Boeing 737.



    We discussed this before, see:


    I am attaching several pages from manuals showing how this is done.

    I just flew this morning and put my astrocompass to use. I flew over a predetermined fix at a specific time and made some precomputations to find the Sun LHA. I dialed on the astrocompass the Sun LHA, declination and aircraft atitude. I made sure it was aligned and level properly. I was able to read true heading and adjust for variation to obtain magnetic heading. It was correct within two degrees. Fascinating how accurate it is. Has anyone used the astrocompass before at night?
