Quote:Likewise if the speed is low enough to make the frequency to be within the bandwidth of the control system the servo can follow the error and no position error can be seen, but the telescope will be moving with the error.

I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.
Quote:I see, one more question though!
On the sketches you posted a while ago on the shaft you
would like to make, did you check if the end of your
RA-axis where the polar scope is screwed into, is trued
If not, screwing your new axis flat against that RA-axis
end which wouldn't be trued up wouldn't make much of an
improvement I am afraid!
Maybe just rotating the RA-axis with a little feeler gauge
against the flat end will show??
I hope to read more on your project, this is very
interesting all together!!!
