Hi all,
Within 24 hours of my warning about Ebay scam messages I've just

Fellow shadow watchers,
If faced with the same old question "What is it that
fascinates you about sundials?" You need look no further than the new book by
Sir Mark Lennox-Boyd, patron of the BSS for support and illustration.

Hi John,
Pity the answers you got weren't on the list.
We now miss the discussion.
I suggest to use the horizontoscop for the problem..
I have such an instrument since years.
It is develloped in Germany by F. Tonne.
On the web I can't find an article about it but I send you off line a

Hi Fer,
I find three pictures of a horizontoscope in my computer -- two of
which came from you in September 2004 and are pretty good images.

Sky Publishing used to sell them. You can set the RA and Dec
of an object and the date and time and it will point to the
position in the sky. Or you can set the Dec and rotat
Yes, several people sent pix of the horizontoskop, and I like it very very much, but it looks like I'd have to purchase cards for every latitude, and some cards may not be available, though close enough, I think. So then I thought perhaps a wide-angle mirror (convex mirror) or mirror garden ball
Mine came with scales for 49, 51, 53 North diagrams.
But you can easily make your own diagram: design a Oughtred sundial with
a diameter of 97mm and you are done!

As my response was accompanied by a jpeg I sent it directly to John. The
picture was of a device seen at the BSS Cirencester conference (with BSS' David

This reminds me of teaching solar water heating back in 1980. Part of
the problem was "site selection". If you Google that phrase you can
still find articles on devices to use. The most expensive is the $255
Solar Pathfinder. Compare that to the "Solar Site Selector" at $30 or
make your own.
Hi John,
Indeed, a horizontoscope is rather expensive just

Thibaud already mentioned to make your own Oughtred

Sunny Day,
On my web site "The Sundial Primer" I have a page "Sun Charts" that shows
the dialling data that can be obtained from these charts.
I have also compiled a number of sun charts that are available on "The
