eq6 10s harmonic

Choppy guiding of around 1.0 RMS, so had a look at the RA motor. Cleaned and re-greased the motor pinion and idler gear. 

The pinion/gear on the stepper motor tooth mesh time of 10s is back. Ah well...

Still OK, but not good to watch so look at the end result instead. One over 4 nights, cloud and wind permitting and the other to fill an hour before dawn.
