As I have a permanent setup my objective is to achieve good balance in all positions. I have my OTA (ASA N10) off the mount (DDM60 Pro) to investigate the radial balance of the OTA.
There is a HUGE radial imbalance of several kilograms (Ok3 plus corrector plus camera).
I have read this thread over and over and I am still not convinced that I really understand.
Are we saying that I do not have to fully balance the OTA radially as long as the remaining imbalance is centred and symmetrical about the plane of the Dec axis?
In other words, if I were to place the OTA on horizontal bars with the focuser pointing down and add small weights to correct the asymmetries until the focuser is perfectly vertical and then ensure the focuser centre line is on the plane of the Dec axis then that is all I need to do?
I have already constructed a counterweight system to fully radially balance the OTA (which is working) but I am concerned about the weight it adds and even more about how far that extra weight is from the mount. And then I would have to add even more to the RA weights. So it is starting to seem like a bad idea to radially balance the OTA in all positions when the imbalance is so large.
So could someone please confirm that fully radially balancing the OTA is actually unnecessary as long as there is no imbalance about the plane of the Dec axis and that the large remaining imbalance in the Dec axis plane will not matter when trying to achieve good mount balance in all sky positions?
