    Brad,

       “Assume a star at 17°S”.   A star with a declination of 17°S ?

        A star with a declination of 17°S will rise on an azimuth of 090+17=107° anywhere within Lat 20N to 20S,  and set on an azimuth of 270-17=253° anywhere from 20N to 20S.  I am just using the rules as a sailor would. It has nothing to do with seasons, or the Sun.

        That star will also go over all places with a latitude of 17°S, every day. and if it is dark, and it goes overhead, you are on Lat 17°S. It has nothing to do with seasons, or the Sun.
