Hi Mario
Your problem may not be fixable with either EQMOD or PHD2.
In most cases the default settings in PHD2 work fine and tweaking them would not make the diference between 0.6" and 1.5"
In any case, the log will show what settings you are using already in case something can be adjusted.
Listing our every single parameter from EQMOD and PHD2 is very difficult.
