4. Getting Started

In order to experience the full GOTO capability of GoToNova technology it is very important to set up the mount correctly before observation.

4.1. Setup the Mount and Polar Alignment

Setup and polar alignment your iEQ75-GT mount according to Section 2.5. The default position for the mount is the Zero Position, as shown in Figure 15, when the mount is powered on: the counterweight shaft is pointing to ground, telescope is at the highest position with its axis parallel to the polar axis and the telescope is pointing to the North Celestial Pole.

4.2. Manual Operation of the Mount

You may observe astronomical objects using the arrow keys of a GoToNova hand controller.

Flip the I/O switch on the telescope mount to turn on the mount. Use ►,◄,▼ or ▲ buttons to point the telescope to the desired object. Use the number keys to change the slewing speed. Then press STOP/0 button to start tracking.

4.3. Setting Up the Hand Controller

The iEQ75-GT is equipped with a GPS receiver, which will receive the local time, longitude and latitude information from satellites after the link is established. A clear sky outside is needed for the GPS to establish its link with the satellites.
