Differences of the remix compared to the original
List of Upgrades in Ver. 2:
- Higher reading resolution dial plate; i.e. 5 minutes vs. original 15;
- Introduction of a secondary Vernier scale to the Alidade which allows time readings to within ½ minute. As in ver. 1, the accuracy will be determined by the quality of it’s construction, assembly and precision of it's final alignment;
- Improved Analemma curve resolution;
- Replaceable Nodus cone with smaller circular sight to improve reading resolution (or adopt your own custom design);
- Improved dial holder ends with better meridian marker and adaptable pedestal for tripod base;
- As in ver. 1, 4 base options are available; 3 with integrated magnetic compass and levels, and 1 without. See original model for the links.
