Hello All,
Helmut's suggestion to incline the gnomon is a good one to solve this problem.
The normal vertical design is less accurate than I originally thought because
the shadow intersects the ellipse at such a small angle. Reasonable time
estimates would be impossible to achieve through most
Hello all,
Have a look at this interactive website
http://www.sunmoonscope.com/
Quite a useful teaching tool.
There are other 'scopes' as well (solar system, astrology), at the top
right hand corner of the screen.
best regards,
Alex
