Fig. 3.3 A colour photograph of the camera head with the TEK CCD mounted. The small carriage with the autoguider eyepiece and optical adjustments is attached to the probe and moves in the X direction as the X position is shifted.  You will observe most comfortably when this carriage is in front of you, or to your right or left.  Note that this image has been rotated  90° clockwise relative to Fig 3.1, in order to put it in the same orientation as Figure 3.2.
