Astrolabe in the Tradition of Chaucer
Until further notice, NASS Shop items cannot be sold or shipped to addresses in the EU.
NASS is pleased to offer an astrolabe in the tradition of Chaucer, following his manuscript of 1390. The astrolabe is 7 inches (180mm) in diameter with the Climate Plate tailored to your latitude.
This working astrolabe is in the English tradition of Chaucer during the period 1326-1400 and will be constructed specifically for your latitude. Although the astrolabe is a medieval instrument, this one has been updated for the precession of the equinox for modern day use. The astrolabe is 3D-printed using PLA plastic.

Universal Bifilar Sundial
The bifilar sundial was invented by Hugo Michnik in 1922 using two orthogonal wires suspended at appropriate heights above the dial surface. Where the shadow of the wires cross, you tell the time. The North American Sundial Society version of this dial adds features to make this a universal sundial that tells civil time. The height of the horizonal wire can be adjusted for the user's latitude and unlike other sundials, the hour lines are uniformly separated by exactly 15°, alowing the dial to be rotated for both longitude and Equation of Time corrections. This dial tells accurate civil time. The dial is 3D printed of PLA filament and is shipped in a USPS Flat Rate Priority Box.
