As Paul mentioned , use Ascom pulse guiding direct to mount ( not ST4 via camera to mount )
Try this ……..
Open PHD2 by itself ( not through NINA )
Run a new calibration near Dec =0 ( near celestial equator and north meridian)
Save calibration ( Auto restore calibration in Brain tab )
Pick an object in the east up at say 40 to 60 degrees
Guide on that object autonomously with PHD2 for 5mins
If guiding is good , return mount to home or park position, shut down mount
Restart mount and launch PHD2 through NINA as normal
Find same object in east and guide on it , if guiding has issues, NINA is your problem
If guiding is problematic using PHD2 by itself without NINA
Delete existing profile and create a new profile using the Wizard. The Wizard is the best method of setting up PHD2 and ensures you don’t miss or skip procedures , foul up on focal lengths of guide camera and miss Dark libraries etc….
Good Luck
Martin
