8. Operation

Adjusting the viewing angle

For the AET22 and EDT22 ergo tubes, the viewing angle can be adjusted by tilting the binocular eyepiece in the range of 5° – 32° (Fig. 61).

Adjusting the eyepiece extension to the arm length

On the AET22 tube, the eyepieces can be ex- tended up to 30 mm (Fig. 61).
