Your E-mail was clear but mine maybe not.
I think that the sats I was mentionning are not absolutely geostationary.
Therefore, the telescope has to be controlled for satellites tracking and
not for the stars tracking, nore fixed. Just in case of long exposures.

My pleasure, avec plaisir,  Alphonse
