PIER ADAPTER

FOR CELESTRON CGE MOUNT

 

According to my plans for establishing a Roll-Of-Roof Observatory I decide to make ready a pier adapter for Celestron CGE equatorial mount.


The aim was to attach the pier adapter to the main concrete pier. Celestron CGE mount attaches to the upper adapter plate in the same manner as attaching to the Celestron CGE tripod.

The design was inspired from the image of CGE pier adapter I have seen in the web site of Michael Paur, a friend of mine from Germany. I am very grateful to him for the entire help I have got for completing my astronomical equipment. The difference is that I decide to use three steel bars (long bolts) and to get easier way for leveling.

The pier adapter was designed to add a finished appearance to the top of the future concrete telescope pier. The pier adapter ought to provides stable platform for CGE. The upper plate matches Celestron CGE electronic pier. The bottom plate allows prime azimuth adjustment with three oval shaped openings.

The top parts of pier adapter are made from duralumin and only the nuts and bars are made from steel. After the fixing CGE pier adapter to the main concrete pier all parts will be black colored to prevent any lights beam refraction.

Once the pier is cured in concrete one could use the three top nuts for level adjusting by a water-level. Then using a wrench the nuts have to be tightened equally as much as possible to maintain level.

Any opinions and suggestions are welcome ...

Notice the oval shaped openings at 120 degrees apart. They allow prime azimuth adjustment of the setup.

The final result - assembled with tree steel bars, nuts and washers.

The steel bars will be fixed within the main concrete pier. After that all parts will be black colored to prevent any lights beam refraction.
