Pier Plate
We used an endmill to shape a steel flange to accept the base of the CG5 mount. I used this in conjunction with two aluminum plates that were bolted together. This was bolted to the top plate. I didn't have any issues with it rotating once tightened down. I was using a 8 in Celestron SE.
A quick search will give you plenty of ideas.
Orion True Track Dual Axis Drive
https://www.telescope.com/Orion-Dual-Axis-TrueTrack-Telescope-Drive/p/7832.uts
This precision DC drive provides accurate, regulated tracking for SkyView Pro mounted telescopes.
The Orion TrueTrack Telescope Drive System offers dual-axis control which is ideal for high-power viewing and astrophotography. Electronic hand controller allows sidereal tracking in right ascension and electronic control of declination. Features 2x, 4x, and 8x speeds, plus pause mode. Thumbwheel clutches on both motors allow use of manual slow-motion controls if desired. Includes two motors, hand controller, and battery pack (four D cells not included).
11 lb. counterweight for use with CG-5 mounts.
Counterweights restore proper balance, increasing ease in handling and improved tracking accuracy.
You don’t need perfect balance to operate your telescope. In fact, it’s not always possible to achieve perfect balance with fixed-position weights. All you need to do is reduce, or eliminate, swing when R.A. and DEC locks are released. Celestron counterweights help you achieve the desired balance and stability with ease.
Get some help polar aligning your Celestron CGEM, Advanced VX, or CG-5 mount with the addition of the Polar Finderscope. Install the finder into the polar finder port, located at the rear of the mount, and focus the eyepiece until the reticle is sharp.
The reticle is etched with a few recognizable star patterns to help you align your telescope. If you are using your telescope in the Northern Hemisphere, you will recognize the Big Dipper asterism on the reticle, as well as the familiar “W” of Cassiopeia. Use the Big Dipper to guide you in the spring and summer months, and Cassiopeia during the fall and winter. The North Star, Polaris, is also designated on the reticle, as is the NCP, or North Celestial Pole. Once you choose which star pattern to use, align your telescope so that the stars line up with the positions shown on the reticle, then move the telescope’s azimuth and altitude adjustment controls to place Polaris right in the crosshairs.
The Celestron Polar Axis Finder can also be used in the Southern Hemisphere. Four stars of the constellation Octans are etched in the reticle. Adjust your telescope until those stars line up as shown on the reticle.
