Description

This Flat Pier Plate (1612FP) has been machined to the specifications of the Advanced Telescope System (ATS) .  It is sized to fit directly into the pier without modifications and provide a mounting surface for our (previously 1200FSA).  It will add 0.75" to the height of the pier.

Owners of 1100GTO and 900 mounts will be pleased that additional holes have been drilled and tapped for our (previously 900FSA).  This is of interest to imagers who are looking for the most robust and stable pier for their larger scopes setups. 

The bottom, pier-inserting portion of this plate has additional thickness to allow custom machining in order to fit a smaller inside diameter pier.  Please refer to the PDF schematic for dimensions.

Pier options:

• Use with the 10" ATS pier (no modification required)
  The base of the 1612FP has already been machined per the specifications provided by ATS to fit into their piers without further modification.

• Use with other piers (may require custom modification)
  Machine the bottom portion of this plate to fit the I.D. of your pier, if necessary. Please refer to the diagram to determine if your pier is suitable.

Top attachment options:

• Attach 10" 1612FSA (use existing tapped holes)

• Attach 8" 119FSA (use existing tapped holes)

• Attach custom  mount adapter (machine custom tapped holes)

If you intend to attach an 1600GTO or older 1200 mount to the ATS pier, then it is best to choose the combination .  It is a two-part adapter that combines both the 1612FSA and the 1612FP. 

Fasteners included:
1/4-20 x 3/4" (8) - attaches 1612FSA or 119FSA to Flat Pier Plate (1612FP)
5/16-18 x 5/8" (6) and washers - attaches 1612FP to ATS pier

Note:  Since the bottom of the flat plate is designed to fit into the 10" ATS Piers, the diameter (9.450") is too small to be used in the Astro-Physics 10" Portable Piers.
