Nico, as a possible explanation, I saw star trails after doing exposure straight after slewing which were caused by backlash in the RA drive. It was visible only after slewing east as the motor had to catch up to the backlash. It was not visible after slewing west. Keep in mind that my mount is not that great...

Any objections to removing the option to do bias-before-exposure from the driver? It is probably just adding about 2s to each exposure without any effect. The sensor clearing in the firmware seems to be doing adequate job.
