Hi Allyn,
It is better if guiding star is close to target, because of atmospheric refraction and because of polar alignment errors.
The near objects have almost the same conditions.

<p> Hi,
Leading on from Robin's question, is there any need, aside from
mechanical considerations of the guidescopes mounting, for the guide
star to be close to the image target? I am trying to set up an old 60mm
refractor as a guide scope. Clearly, this will need pretty bright guide
stars if I am going to use an unmodified ToUcam.
