Re: Strange Mach2 RA oscillation.


 

This is so familiar.  Years ago, I wasn't able to balance a new heavier load on my Celestron CGEM with the stock counterweight bar and weights.  I had the facilities, so the "obvious" solution was to turn a 6" extension to the bar and move the weights out more.  The first (and last) time I used it I immediately noticed very wobbly and lengthy settling after any movement.  It needed more weights closer to the mount - not the same ones further away!
