  • The 900 Hi-Lo Latitude Wedge from Astro-Physics can be used, along with a 900SPA Standard Pier Adapter or Rotating Pier Adapter 900RPA (sold separately) to properly position your AP 900 mount on a pier for polar alignment if you will be observing in latitudes below 20º or above 68º.
  • If you do not already have a Standard or Rotating Pier Adapter, you will save a little money by purchasing the 900 Hi-Lo Latitude Wedge Assembly.
  • It is easy to adjust the Wedge for either tropical (0 - 20º) or polar (68 - 88º) by removing the flat plate and rotating it so that the Azimuth Adjuster Block sits on the low side or the high side. Then simply reattach the plate.


Astro-Physics Hi-Low Latitude Wedge for AP 900 Series Mounts...

If your latitude is below 20 or above 68 degrees, this Hi-Lo Latitude Wedge will allow you to place your 900 mount in the proper position for polar alignment when paired with a Standard Pier Adapter or Rotating Pier Adapter, which is sold separately. Just transfer the azimuth adjustor block, the center pivot screw and the four locking knobs supplied with your original pier adapter to this wedge and bolt it onto your pier.

Please note that this adapter must fit inside another part and be bolted from the side. It cannot be bolted directly onto a flat surface. For custom installations onto a flat surface, insert the 900WDG into the 900 Flat Surface Adapter (900FSA), which has been bolted to the flat surface of your pier.

The 900 Hi-Lo Latitude Wedge can be set up for either tropical (0-20 deg.) or polar (68-88 deg.) latitudes. Simply remove the 6 screws that attach the flat plate, rotate the plate so the Azimuth Adjuster Block will either be on the low side (tropical 0-20 deg.) or on the high side (polar 68-88 deg.) and re-assemble.

The 900 Hi-Lo Latitude Wedge can also be used with the 900 Precision Adjust Rotating Pier Adapter (900RPA) to make polar alignment easier for mounts used in the field. The Wedge has been drilled and tapped to accept the 900 Flat Surface Adapter (900FSA). Attach the Flat Surface Adapter to the top of the Wedge with four 1/4 - 20 x 3/4" socket head cap screws (not included).
