Tightening EM200 Dec Clutch

Dear all,

I have an EM200 for a year but note that the Dec clutch is not
tightened enough, such that even if the Dec is apparently balanced and the Dec clutch tightened by my thumb, the stars still drift along the Dec axis.

I later try to re-tighten the thought-to-be already tightened Dec clutch a bit and am surprised to find that it could still be slightly moved further. However, while the stars' drift problem
lessens a bit, I can still notice slight stars' Dec drift, about
several arc seconds away per second.

How can I make sure that the Dec axis will not move after I tighten
the Dec clutch ?

All comments are welcome.

Hi Raymond,

I checked my EM200 and it does not do the same thing.

It sounds to me like you need a service.

I would contact Art at TNR
