Peter,
The relationship between your telescope/imaging system and its alignment with the Dec axis (and RA) isnt being considered.
If the scope rings, optical axis, scope tube, mirror collimation is out - it doesnt know.
So even if they can eliminate the difference between the RA axis and the PoleMaster, its still not fixing a common problem that a full Tpoint model is designed to correct.
Even just using the 6 standard terms that Tpoint defaults to, will eliminate the most common errors that are probably in existence in almost every system. so it makes sense to use Tpoint still - even if you use PoleMAster as well !
I guess people can use whatever they like, but to discard a tool that not only provides an accurate Polar Alignment report well beyond the capability of the other option, but also goes on to correct (in software - using TheSky) all the normal geometric problems inherent in most systems and with a more expanded model, all the rest of the problems just seems retrograde.
These comments really applies only to systems using TheSky where the Tpoint model is fully integrated into the pointing and tracking control.
Ill try and find the video.
