I'm pretty sure they use what is known generically as damping grease. There are many grades and the specific one that optimises the gear performance is the secret. But if you google damping grease you might find some to try and work out which is best for you.

@ OzAndrewJ:

The Dec motor is indeed identical to the RA motor, so maybe I'll swap them in the future to see if it make any difference in the PE behaviour, thanx for the sugestion!

I also tried pempro viewer, but it won't execute in my Win XP imaging laptop, gonna try this on another pc this week.

@ KenS + Wichwayisnorth:

Thanx for the advice about the lube, I indeed used PTFE superlube for the gearhead, for one motor to test the sound compared to the original lubed motor, and the conclusion about the motor containing superlube, is that it runs smooth and less noisier.
I'm gonna check out the thread about grease for sure, been reading a lot about grease the last months, very interesting.

For future pe measurement I fist have to find out what about the 2x sidereal movement of the mount.
Because it seems I cannot change this in the Starbook (mount controller), and first I thought I found the problem in the sphinx Ascom driver, which sidereal setting was on 2x... but when I tried to set it on 1x, I saw this was not possible, see the picture below... guiding rate to sidereal rate from 2 to 792 ?
For guided images on mosquito's I guess...
