Re: Orologi Solari n. 2
Gian, thank you for posting the link to the new issue!
I was particularly taken by the lovely and simple polar dial/meridiana at
Certosa di Vedana.
I believe I am going to have to build one for my home; it will be a nice piece
for my front yard (South-facing.)
Can you or anyone else on the Sundial List recommend one of the several pieces
of software that have been graciously made available to us, that can most
easily create a plot of the analemma for a specific location on an equatorial
plane?
I have been experimenting with apertures and roughly sizing the piece, and it
works very well with a pinhole of 5 to 10 mm diameter and a centerline
distance of ~50 cm. Adding a 2 diopter lens (i.e., 50 cm focal length) sharpens
the solar image nicely, and still works fine at 25-30 degrees off axis, as it
would be at the solstices. That size would allow me to plot the curve on 11x17
paper in one piece, making for easy transfer to the equatorial surface...
Still undecided about whether I should design it for civil noon or local solar
time. :{)

R: Re: Orologi Solari n. 2
Dear Dave,I agree with you on the fascination of this instrument that comes I
guess from its simplicity.
Regarding a software tool to draw the analemma, I cannot avoid suggesting you
my Orologi Solari program, but I am sure that several other programs can
pefectly suit your needs.
The choice between solar and civil time is always a dilemma.I usually choose
civil time, just to avoid a lot of questions about the time difference between
sundial and wristwatch time.
Greetings.Gian

Somehow, I thought youd suggest that! :{)
It was going to be my first thought, as well.
Thanks!
