Here is a quick update on the tracking telescope project. The telescope is equipped with a dual-axis direct-drive mount with 26-bit optical encoders.

A Servosila team working on the project managed to improve the control laws so that more noise is rejected, and got to the following improved results:
- The static angular positioning accuracy is now 25bits out of 26bits.
- The dynamic tracking accuracy at angular speeds of ~2deg/sec is 22-23bits.

These are nearly perfect results as far as what can be possibly achieved with 26bit encoders in real life settings.

The good news is that the improvements in the firmware and the control laws are now shipped with all stock SC-series controllers (SC-25 & SC-60), so that you could achieve similar results in your applications, too !
