Thanks to Peter_4059 I have been able to achieve some promising drift alignment results. I then moved on to a N-star alignment with EQMOD 1.17d, which has a significant change to the alignment interface, apparently requiring use of the SYNC function to accept a star. I have yet to find a user guide for the new version.
When you click on the telescope function in Stellarium it initially asks you if you wish to slew or sync. I selected slew and clicked the little box to always do a slew, thinking I could change it later.
I can't find anyway to change it as the box no longer comes up, it always slews

, so I can slew the scope to a star, align it correctly, but am unable to sync, so can never complete the alignment.
The 10.2 user manual is still very short on telescope control info, so Barry, what's the answer? I tried CDC and all worked fine, but I would prefer to use Stellarium if it will do the job.
