EQMOD does have a polar alignment feature which requires the use of your polar scope ( I don’t use this )
As far as star alignment for Goto functions , EQMOD has a sync based algorithm in its pointing model when used through your planetarium ( Stellarium or Cartes du Ciel etc... )
The 2 algorithms available are 3 point plus nearest and nearest point which you can select
I use 3 point plus nearest which is excellent
It would be helpful for you to read up on EQMOD
The manual is available on their website
www.eq-mod.sourceforge.net
Don’t know if this answers your enquiry
