RE: Right ascension on sundials

Hi Dan,

 

There are numerous examples in the excellent book “The Double Horizontal 
Sundial” by John Davis and Michael Lowne, available from the British Sundial 
Society on their website. DH dials include a projection of the celestial sphere 
between the solstices, show the ecliptic and optionally star positions.

Hello,

 

Are there sundials showing the Sun's right ascension? Can you please post a 
photo? Thanks!
