Focusing and Orientation of the Guiding Bundle

The end of the guiding bundle in front of the TV camera can be focussed using the manual mechanism (see Figure 5). The same procedures as those described for focusing the acquisition bundle should be adhered to here. If procedure i) is used, the sharpest image of the space between the two bundles indicates the best focus position.

As is the case with the acquisition bundle the correct orientation is currently indicated by a painted mark, but again, we anticipate that the bundle will be shortly doweled into position.

In the standard configuration the inner (outer) field is to the right (left) of the TV screen.
