Your welcome Raphael, thank you. Happy to help!

I don't see any advantage of imaging with autoguiding in combination with easytrack except if your DSC is not working, so a good backup solution!
PHD2 will not have to work/correct as much when you have done the 2-star alignment because of more accurate tracking, but it could potentially still correct to the same RMS error.

PHD2 is very good, and made for correcting low frequency errors like slow drift. Which is the case when using easytrack compared to a good 2-star alignment.

Edit: It is not possible to point at all with Easytrack, you would have to use a Telrad or similar, just like when doing visual.
