1200 Hi-Lo Latitude Wedge Assembly for 0-22 or 69-90 Deg. (1200WDGA)

If your latitude is below 22 or above 69 degrees, this wedge will allow you to place your 1200 mount in the proper position for polar alignment. Under normal circumstances, you will use this wedge in place of the Standard Pier Adapter (1200SPA) or Precision-Adjust Rotating Pier Adapter (1200RPA) shown above. This wedge comes complete with the azimuth adjustor block, the center pivot screw and the four locking knobs with their washers. The pier adapter also includes six 5/16-18 x 5/8 socket button head screws and six 5/16 x 9/16"OD x 0.060" flat washers, which enable you to attach the pier adapter to your Astro-Physics 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. If you wish to attach to a flat surface, use our 1200 Flat Surface Adapter (1200FSA).

The 1200 Hi-Lo Latitude Wedge can be set up for either tropical (0-22 deg.) or polar (69-90 deg.) latitudes. Simply locate the Azimuth Adjuster Block either on the low side (tropical 0-20 deg.) or on the high side (polar 68-88 deg.) in the drilled and tapped holes provided. Tapped holes to reposition the north and south locking knobs for the high latitude configuration are also provided. The low latitude arrangement is shown in the images at left and is how the wedge is shipped.

The 1200 Hi-Lo Latitude Wedge Assembly can also be used with the 1200 Precision Adjust Rotating Pier Adapter (1200RPA) to make polar alignment easier for mounts used in the field. The Wedge has been drilled and tapped to accept the 1200 Flat Surface Adapter (1200FSA). Simply remove the four Locking Knobs and the Azimuth Adjuster Block and attach the Flat Surface Adapter to the top of the Wedge. (Just 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.

Mounts: All 1200 mount models (DA, QMD, SMD and GTO) that have been produced.

1200 Flat Surface Adapter (1200FSA)

Use this Flat Surface Adapter to attach the Precision-Adjust Rotating Pier Adapter (1200RPA) to a flat plate on your custom made pier or tripod. You can also use it with the Standard Pier Adapter (1200SPA) to give a more finished appearance.

The 1200 Flat Surface Adapter is precision machined aluminum. It has been polished smooth and then anodized black.

The Flat Surface Adapter bolts onto the flat plate on top of your pier or tripod, then the Pier Adapter simply slips in (just as it fits into our pier) and you fasten from the side with the six screws and washers provided with the Pier Adapter.

The bolt circle for attaching the 1200 Flat Surface Adapter to your pier is 9.230” in diameter. The holes for mounting the 1200FSA to your flat surface are counter-bored to accept the head of a standard ¼” socket head cap screw (13/32” or 0.406” diameter).   This allows the Pier Adapter to sit perfectly in the Flat Surface Adapter. Because installations will vary, we do not provide the four screws for mounting the Flat Surface Adapter to your pier or tripod. Your pier's top plate should be a minimum of 9.75" in diameter. The 1200 Flat Surface Adapter itself is 10.375" in diameter.
