SUNDIAL FRO SOUTHERN HEMISPHERE

[Leslie Lombard]

I live in Johannesburg South Africa at 25degrees 48minutes South and 28 degrees and 15 minutes East.  I have tried unsuccesfully to use some of the freeware available to construct a declining North facing vertical dial for the Southern hemisphere.  The wall declines 27 degrees West of North.  Can anyone help or advise the availability of suitable software?   Thank you Les Lombard ( [EMAIL PROTECTED] )
