Astro-Physics M12020-A 1.2" Azimuth Adjuster Block
If you purchase the Azimuth Adjuster Assembly (S1200AA-A) and use the Standard Pier Adapter, you may wish to consider upgrading to the new taller Azimuth Adjuster Block, as well. Although the original 1.1" block will work effectively with the new adjuster assembly, this new 1.2" provides a better connection for the opposing screws and looks proportionate. This is a suggested, but not essential upgrade. This block is not needed if you use the Precision-Adjust Rotating Pier Adapter (900RPA) or if you are ordering a new Standard Pier Adapter (900SPA) .
Mounts: All 900 mount models (HDA,QMD, SMD and GTO) that have been produced.
