I have the GTOCP3 panel on my 900GTO and like to try to track the ISS from SW horizon to NE horizon with no meridian flip.
I don't use Ascom or APCC when tracking the ISS.
To do so I change the meridian delay in keypad from 0W to 6W(western horizon)
That keeps the scope on the west side for any position in the sky.
My starting point is with the scope upside down and pointing above the SW horizon.
