I noticed the last observations that the tracking isn’t smooth anymore in RA of the ASA DDM85 mount. I checked the balance again and noticed if the telescope is on the other side of the mount the RA-current to the motor was much higher, while the balance wasn’t changed. So i contacted ASA and tols me that it is best to send the mount in maintenance/repair. Possibel is there a problem with the bearing of the RA-axis, after 9 years of working. So i removed the telescope, a hug and difficult work because this is a huge instrument and heavy (about 50 kg). Then packed the mount and sending for repair to ASA in Austria.
