    Hi,
     
    Here are some files I've found regarding the astro compass.
     
    Here's basic instructions.

    Here's more detailed instructions.

    pages 250 to 257
     
    Here's a little blurb on page 40  about using it as a pelorus.

    These two  are also interesting

    Lastly,  What the astocompass is, is a torquetum, with the ecliptic plate removed.
