Dear all,
I have just purchased an EM200 Temma 2 mount and find a strange phenomenon that the RA setting circle (already tight-fixed with its 2 little screws) does not move with the RA motor (when pressing the hand controller or through stewing through The Sky GOTO) when the RA clutch is tight.
However, when I loosen the RA clutch, the RA setting circle can move when the RA axis is manually moved. This meants that the RA setting circle can only be used in manual mode.
The DEC setting circle is alright, however. It moves with DEC axis either manually or through DEC motor.
Perhaps some experienced EM200 mount owners can comment on the strange behaviour of the RA setting circle.
Thanks
Raymond
