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

    If your latitude is below 20 or above 68 degrees, this Hi-Lo Latitude Wedge Assembly will allow you to place your 900 mount in the proper position for polar alignment . It comes complete with the azimuth adjustor block, the center pivot screw and the four locking knobs with their hardened washers.

    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). Just remove the four Locking Knobs and the Azimuth Adjuster Block and leave the center pivot screw in place so it won't get lost! Then install the Precision Adjust Rotating Pier Adapter into the Flat Surface Adapter. Note: The photo is of an earlier version and does not show the holes that accept the flat surface adapter.
