Here is my version of the 2102-D, upgraded to the 2102-E. Some general directions for use. 1) Just play with the slider bars, don't attempt to type in your desired values, as that has no effect 2) You can adjust the Day of Year, which places the solar disk 3) You can adjust the Latitude (most fun) to see ANY latitude clear overlay 4) You can adjust for Aries 5) You can rotate the stars 6) You can select northern or southern hemisphere. PLEASE DONT USE THIS FOR ACTUAL NAVIGATION. Its just a toy. Depending upon your settings, you may have to enable content. For those who want to see how I made it work, you will have to unhide worksheet elements. There is no password protection, I just hid the sheets so it wouldn't be destroyed immediately by "poking around"! The key to the entire deal is azimuthal equidistant. The mathematics are published in many places. Enjoy!
