Yes, another question
I have the Ioptron CEM25EC mount. And for balancing an Ioptron CEM mount I see/read that it is done for each axis separate: first balancing DEC, lock it, then balance RA axis.
But I am used to check the balance with both axis free: when moving the RA axis from one end to the other (so 180 degrees), the DEC axis should stay (almost) stable on it's own axis, constantly pointing in the same direction as where the counterweight is.
And when the movement of the RA axis is stopped (in any position), it should stay in that position and the DEC axis in it's position.
For me this is logical: the whole system is in balance, no matter the positions and the strain on the motors is also balanced. But when each axis is balanced separate, there is no "real" balance: when the RA axis is moving, the DEC will become more unbalanced when the RA axis angle increases and the strain on the motor will also increase because of that.
And that is no theory: I tried separate balancing per axis and then, when moving by hand with both axis free, indeed the DEC will go out of balance then when the RA axis is moving.
So, am I crazy? Is there something I am missing?
