Hello All,
John Close has posted this message on the NASS Message Board:
"Does anyone have any ideas for a Polar Dial which allows for an
Equation of Time adjustment. I would not like analemma shaped hour
lines as I think this would detract from the simplicity and
minimalistic quality of a Polar Dial. I am told an analemma shaped
gnomon for a polar dial would be hideously complicated and probably
not work . Any ideas anyone? John Close"
John has discussed this problem with several members of this list,
including me, Bill Gottesman, John Davis, and Pete Swanstrom. Some of
us think that a 3-D gnomon could be designed for use with straight
hour lines to correct for EoT, and some are skeptical.
Please share your comments and suggestions.
Best wishes,
Mac Oglesby
P.S. Since I do not know if John Close is a member of this List,
please cc to him.
