...Azimuth position encoder work

...azimuth-position absolute encoder installed; direct, on-axis coupling. Encoder used is a US Digital Model A2-S-B-MHS to provide 0.1 degree azimuth-position resolution (February 13, 2005).

...azimuth absolute encoder mounting detail. A weather shield will be added later (February 13, 2005).

...azimuth absolute encoder mounting detail. A nylon coupling shaft is used to provide a semi-flexibile coupling to accommodate any slight axial mis-alignment (February 13, 2005).

...next up is installation of the elevation hydraulic system and installation of the elevation encoder...all on the az-el mount.
