Oh, it's a really nice one, but as far as I remember, there is a hint in Rafael Soler's
book on a dial like these (in the chapter about equatorial sundials). Anyhow,
it's just a hint, not the whole device as you show.

Subject: A new sundial - type from Bremen!

Dear friends,

may I invite you to have a look at a probably
new type of sundial,
an analemmatic equatorial sundial with light-pointer,
built by my friend
Dietrich Ahlers.

His
HALBE - ACHT - sundial
can be seen at the Homepage of
Olbers-Planetarium Bremen as sundial of the month March.

Either you start at:
http://www.hs-bremen.de/planetarium

and choose bottom right <Sonnenuhr des Monats> (sundial of the month)
or go directly to:
http://planetarium.hs-bremen.de/planetarium/astroinfo/sonnenuhren/ahlers/analem.htm

Regards
Reinhold Kriegler
