5.3 Tube and Eyepieces

The tube is mounted to the stand either directly or with the use of intermediate modules. It is fastened in place with the side clamping screw (9.1).

•Loosen the clamping screw (9.1).

•Insert the tube in the circular receptacle (dovetail ring).

•Retighten the clamping screw (9.1).

•Only for the MBDT motorized tube:

Connect the tube to the stand with the con- nector socket (10.1).

•The eyepieces are inserted into the eyepiece tubes on the tube.

6.4 Objectives

The receptacles on the objective turrets are numbered (Fig. 11). The individual objectives have already pre-assigned positions at the factory according to their configuration.

A list of the exact objective positions is provided in shipment. (“Identification Sheet”)

!Caution:

Cover unoccupied threads on the turret with dust protector caps!
