I am building a ROR observatory in my backyard. Budget considerations may mean a home made pier. My background has me considering a four inch steel schedule 40 pipe welded to two steel flanges bolted to a twelve inch sonotube base. I have a Celestron AVX mount and have learned that the 1995 Ford Fiesta 1.4 litre front disc rotor has the exact axle hole to provide the female to the AVX male. All that would remain would be some machine shop work to mate the two flanges. I have a feeling that a car that old is going to be hard to find. Has anyone else done this with a late model car? Please do not give me any feedback on the folly of my quest, I know the peril of my choice. If the stock of a certain company I used to work for starts to go up, then it is all academic (**** Alberta oil patch!). Are there any late model cars that match the AVX?
I am hoping somebody else has done this with an AVX. The engineered metal piers you can buy are pretty awesome and have some pretty sound physics behind them, but Holy Crap, they are expensive.
I am very new to the hobby and I am building now. I would like to do astrophotography with my EDGE8. How solid is solid? How good is good? When do you get to a point of diminishing returns when you are constructing or buying a pier for your backyard telescope for your own images that you hope to get pretty good at eventually.
Thanks for any help.
