900 Precision-Adjust Rotating Pier Adapter with Azimuth Bearing (900RPA)
This item is out of stock but you can place an order now and we’ll ship when it becomes available.
The new pier adapter rotates on a bearing surface for ultra-smooth operation. This allows you to lock the mount down with no need to loosen the base during azimuth adjustment. This option is especially recommended for use in the field. You may wish to purchase two or more of these assemblies to install on separate piers. Perhaps you have a permanent observatory and a portable pier for traveling to dark sky sites.
Two assembled machined plates
Four machined aluminum lock knobs
Four 5/16 x 1.5"OD flat washers
Azimuth adjuster block
Six 5/16-18 x 5/8" socket buttonhead screws
Six 5/16 x 9/16"OD x 0.060" flat washers
All machined parts are black anodized and the fasteners are stainless steel. This adapter will mount directly into an Astro-Physics Portable Pier. The Precision Adjust Rotating Pier Adapter can also be used in conjunction with the 1600 Flat Surface Adapter (1612FSA) for installation with your own custom pier or with the 1200 Hi-Lo Latitude Wedge (1200WDG).
All 1200 mount models (DA, QMD, SMD and GTO) that have been produced.
Note: The Azimuth Adjuster Block on this adapter is designed to be used with the Heavy Duty Azimuth Adjuster and does not need to be upgraded.
