My astronomy project:
Building a pier to my EQ6 / HEQ5 mount

Contents:

1. Introduction and steel plate
2. Making of the two concrete piers
3. Assemble it together
4. Find north and level mount
5. Drainage
6. Adapt the pier for HEQ5 mount
7. To be continued

Who is the person who don't want a permanent observatory? With a observatory you can leave parts of your equipment in place and have a polar aligned mount ready for astro photography.

I already have the EQ6 mount and had drawing some planes how to mount it on a self made concrete pier. I started with the steel plate that will connect mount with the concrete pier.

I was lucky to find a workshop that could manufacture these steel plates, I let them made two of them.

I chose the size 25 cm in diameter and 12 mm thick. Little bit to big for my EQ6 mount. But that leave space to mount a EQ8 when I get tired of my EQ6. Note that there is a small notches in the edge of previous cutting but it doesn't matter. I placed my holes very far out on the edge of the possible because of future EQ8 demands. There are three 18.1 mm holes and in the center a 12 mm. Later on, I also drill a hole and thread for stop to the mount head.
