PART I : SETTING UP THE VIRTUOSO GTi MOUNT

1.1 Installing the Telescope

1. Loosen the altitude clutch wheel and rotate the saddle until the dovetail groove is horizon-

tal, then tighten the altitude clutch wheel again (Fig 1.1a).

2. Loosen the dovetail locking knob until nothing is obstructing the dovetail groove in the sad-

3. Hold the telescope horizontally and slide the dovetail bar of the telescope into the dovetail

groove of the saddle (Fig 1.1b).

4. Tighten the dovetail locking knob until the bar is securely locked in the groove. DO NOT

LET GO OF THE TELESCOPE UNTIL YOU ARE SURE IT IS FIRMLY ATTACHED TO

THE SADDLE
