Sandy A good example of a corrected armilliary dial is shown in the NASS Compendium for December 2007, Vol 14/4, page 24, This is a dial in Grand Haven, Michigan, which is corrected for longitude (86 W) and Daylight Saving Time (DST). -- Mike Isaacs --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
