ASTRO-PHYSICS German Equatorial 1200GTO, Manual, Page: 12 / 38

Hi-Lo Latitude Wedge Pier Adapter Assembly (1200WDGA) or Wedge Alone (1200WDG) for 0 - 22°
or 69° - 90° Latitude – North or South
If your latitude is between 22° north and 22° south or above 69°, either north
or south, this wedge assembly includes everything you need to place your
1200 mount in the proper position.
The 1200 Wedge Assembly includes the machined wedge and flat plate, the
1.2" Azimuth Adjuster Block, four Pier Adapter Knobs with 5/16" ID x 1 ½" OD
flat washers, the center pivot screw, 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: The photo shows the Hi-Lo Latitude Wedge
ready to be used at tropical latitudes with the Azimuth Adjuster
Block on the low side. For extreme polar latitudes, the
Azimuth Adjuster Block can simply be moved to the high side
of the wedge to extend the useful range of your 1200GTO
above 69° latitude. All required tapped mounting holes are
provided.
Attach to an Astro-Physics pier: To attach the Hi-Lo Latitude Wedge to your Astro-Physics pier, simply set the adapter into
the top of the pier post, make sure the azimuth adjuster block is on the pole side, and fasten from the side with the six screws
and washers provided.
Attach to a flat surface on your own pier : The Hi-Lo Latitude Wedge must fit inside another part and be bolted from the side.
It cannot be bolted through the top as you can with the Standard Pier Adapter. For custom installations, we recommend our
1200 Flat Surface Adapter (1200FSA). The Flat Surface Adapter bolts onto the flat plate on top of your pier or tripod, then
the Hi-Lo Latitude Wedge Pier Adapter slips in (just as it fits into our pier) and you fasten from the side with the six screws
and washers provided. The bolt circle for attaching the 1200 Flat Surface Adapter to your pier is 9.230” diameter.
Using an ATS pier: The O.D. of the plate will need to be modified by ATS for an
additional charge.
More Options: If you already own a 1200Standard Pier Adapter, or if you would like
to construct a “Precision Adjust Rotating Wedge,” you can simply order the 1200
Wedge by itself (It will come with the six 5/16-18 x 5/8 socket button head screws
and six 5/16 x 9/16"OD x 0.060" flat
washers). To use the wedge in place of
a Standard Pier Adapter, simply transfer
the knobs, Azimuth Adjuster Block and
Center Pivot Screw to the Wedge. To
create the “Rotating Wedge,” mount a
1200 Flat Surface Adapter (1200FSA)
onto the top of the wedge using the holes
provided, and then insert a Precision
Adjust Rotating Pier Adapter (1200RPA).
