In trying a new technique for polar alignment I've noticed an issue with the RA setting circle. Either this is new or I missed it previously but not sure how I could have overlooked this. Anyway, here is the issue.
If I grab the fork arms and manually move the scope in right ascension the RA setting circle immediately moves a very small amount (1/4 degree or so) then makes a small, distinct clicking noise and stops turning as the fork arms continue to turn.
However, if I move the fork arms by using the RA adjustment knob only there is no movement in the RA setting circle.at all - which is the way it should be.
Also, I can rotate the setting circle to set it without any issues, it seems fine in that respect. And, as far as I can tell the setting circle is being driven correctly by the motor drive - I'll try to check that tonight.
Hoping someone can let me know what might be causing this. Thanks in advance.
Clear skies, Tim
