It doesn't matter where you suspend it, it would not work. Ships move.

A - a large brass plate with a non-stiff telescope would work (I already posted a statement to that effect). However, you reject the notion that the plate is large. B - a smaller brass plate is supported by the telescope. I already posted a statement on the same - the telescope needs to be stiff to support the plate. Pasteboard won't do. > That applies only to Mike's special interpretation of the instrument, and to > the Royal Society engraving.

I'll accept anything that can be reasonably proved. I've seen no such proof. You are continually referring to some mythical Newtonian instrument that you never describe and is completely undocumented. Provide a reliable source or drop the fantasy.
