However I have found the book Sundials How to Know, use, and Make them by Mayall and Mayall to be very helpful.
I am also using the following internet resources: Sky and Telescope Magazine Web Site Astronomy Software for Personal Computers http://www.skypub.com/software/software.html DIAL.BAS Dec 87 p646 Design a vertical sundial The above freeware program will produce coordinates for you to lay out a vertical sundial. The narative and program description is in the Dec. 1987 Sky and Telecsope Magazine. The program is written in basic. I hadn't used a basic program in 10 years (ever since my Commodore 64 was new). Basic does have its quirks. In order to design a vertical sundial you need to know the declination of the dial. I plan to use the method outlined in the Dec 1987 Sky and Telescope Magazine. In order to do this you need to know the azimuth of the sun at a particular time. I plan to use the MYSTAR program for determining the azimuth. MSDOS Senior Astronomy Shareware http://www.gu.edu.au/aeres/edsw/d-astron.htm MYSTAR.ZIP Shows the position of sun & planets from anywhere (83k) This is a shareware program that you can download from this site. You need to unzip it (use pkunzip to expand the program). The pkunzip program that I used, I downloaded from AOL. I am sure that it can be found many other places as well Happy dialing, Ed
