4.2. Explore GOTO and Tracking Capability
In order to experience the full GOTO capability of GoToNova

technology it is important to set
up the mount correctly before observation.
4.2.1. Level the Mount and Set Initial Position
Leveling is critical for good GOTO and tracking accuracy
Level the mount by observing the bubble (shown) on the base of the
mount by adjusting the tripod legs. The bubble should be in the
center of the circle. The leveling is very critical for a good goto and
tracking accuracy. You may use an additional torpedo level to
assure a precise leveling, or calibrate the existing spirit level. Turn

the mount around by pressing ► or ◄ button to make sure it is always leveled, or the bubble

stays in the same position, during rotation.
Initial Position
Each time the mount is turned on the default position is Park Position, (i.e., its altitude is 90º0.0’
and azimuth is 180º0.0’. There might be a few seconds difference) which means the “SOUTH”
mark is pointing to south and the telescope is pointing straight up at the zenith.

Note: You can always improve the initial position later during “One Star Align” or “Sync to
Target”. To set the Park Position you can:
Target”. To set the Park Position you can:
1. Align the mount to south by releasing the azimuth lock half a
turn and rotating the mount so that the South mark faces south.
An additional compass is needed. Unlock the altitude lock (#4)
and rotate the telescope to point straight up at the Zenith. Put a
torpedo level on top of the optical tube may help. Make sure the
mount is leveled. Then turn the mount power on.
