Hi Jacob.
You need to put the pictured setup on the scope in the focused, rack the focuser till you reach focus on the main camera. Make a not of that position.
Next, rack the focuser till you reach focus with the guide camera however much this takes... note that position. Now, the difference between the two positions that you noted is the amount you need to space or remove spacers from one of the cameras.
Does this make sense?
