At what weight attached to OK-3 a counterweight on the opposite side of the focuser is necessary?

Hello all,

 

I am referring to the following post:

 

http://forum.astrosysteme.com/index.php?/topic/96-cant-move-more-than-a-few-degs-in-dec-position-error-clear-servoerror/

 

 

Philipp raised a point in his feed back concerning balancing the tubus especially with heavy ccd equipment attached to the focuser.

 

It would be very much appreciated if users could post their solution for balancing the tubus if heavy equipment is attached to the focuser.

 

(I was browsing pictures in google looking for solutions, but I did not find any setup with a weight attached to the opposite side of the telescope's focuser...)

 

What weight is heavy? 3kg? 5 kg? 

 

Clear skies,

Christian
