I have been looking worldwide for some info on "Rotating Rings" for equatorial mounted Newtonian type scopes, they appear to alleviate the need to be an acrobat when using your scope as the tube can be rotated quickly to allow the focused to remain at the side and not upside down for example.

Has anybody any ideas of how these could be fabricated both locally and cheaply as a set of commercally availably rings that I think would possible suit my scope are in excess of $US400.
