If the distance from the pivot point to your eyepiece is for example 1200mm,
and the counterweight[s] will be mounted for example 400mm the other side
of the pivot point, then the counterweight[s] will need to be 3x the weight of the eyepiece, because the eyepiece is 3x as far from the pivot point as the weight[s] are, and yes, simple answer to your question, 2kg. Put simply, however many times further the eyepiece is from the pivot point than the weight[s] are, is how many times heavier the weight[s] have to be.
