Yes you are correct about the coordinates. But you have to have the motor and dish aligned to thor in the first place otherwise you are never gonna get the satellite arc right.
bo.
Sorry but you are wrong.
You can't just point it at Thor and expect it to track the arc correctly.
The motor and bracket have to point south, I know Thor is only 0.8 west of south but what if you live at 3west, pointing at Thor would give incorrect arc.
