And got the following answer:
However you want. How good are you at making things? I make telescopes and equatorial mounts like thousands of amateur astronomers do, mosty bulding the mounts from scrap, whatever I can find. Here's a mention of highly 'engine-ered' one..right down in the edit from Mounts http://uk.answers.yahoo.com/question/index?qid=20091122083238AAxR6It . . . . . Alumnised Mylar film (space lanket) can be used for a reflecting surface and stiff wire or metal poles can make the flexible support. Motor drives for astronomical telescopes which follow the Earth's rotation are easily available and will turn a 5lb -150lb reflector if you get the bearings good enough and a strong enough motor. Bearings csn come from bicycle or motorbike wheels, old lawnmowers etc. http://www.go-astronomy.com/telescopes/telescope-drive-systems.htm . . . . http://www.opticalvision.co.uk/astronomical_accessories/motor_drives_and_goto_upgrades . . . . . Large clock mechanisms can also be used,eg from mantelpiece clocks, with the clock mechanism regulating a falling heavy weight to provide the power, or you can use water (clypsidra) or sand clocks like giant egg timers, using a weight on the sand or a heavy float for the water clocks to provide the power via levers and chains or cords, with the motion regulated by the size of the leakage hole. This telescope is driven by a clockwork motor...see the last sentence http://projects.exeter.ac.uk/nlo/Observatory___Telescopes___Kensington~EN.php . Simple equatorial mounts are easy to make, with one axis parllel to te Earth's axis, pointing at the pole to follow the Sun's or a star's movement with only that one axis turning.. Mount the reflector onto that axis either directly or via another at right angles for up and down adjustments to point the reflector at the Sun accurately, and it will follow the Sun, and you can drive the axis as above. http://www.google.com/search?hl=en&q=simple+equatoril+mount+home+made
