One last thing, excuse my ignorance, but what is a shadow sharpener
and what is its use?
Thanks
AP
Hi all, I am as ignorant as Alexei, so I'd gratefully apreciate any
hint (or link) on what a shadow sharpener exactly is.
Best wishes,
Anselmo

Hello Anselmo, and others,
If you search the sundial list archives, you will find lots of
previous messages about shadow sharpeners. Go to the NASS website
(http://sundials.org) - Links. Scroll down to General, and click on
Search on previous postings to the sundial mailing list. This Yahoo
archive covers from early January 1998 until early July 2001. I have
no idea why it stops then. Another archive (http://astroarchive.com)
covers recent messages also (as well as messages from numerous other
astronomy-related lists). I don't know of any archive that goes back
to the start of the sundial mail list.
What's needed is for someone to assemble the information from all
those postings into a fairly brief, but accurate explanation of how
to use and understand shadow sharpeners. Even after all that been
posted on shadow sharpeners, some of us just learned some important
new things about them.
Best wishes,
Mac
