Part IV – Observation

After aligning the telescope, the motors in the mount will begin to move the 
telescope so that the Earth’s rotation is compensated for and the objects 
stay in the field of view of the telescope.

Note:

 If you have aligned the telescope, don’t move it manually. Use the 

arrow keys on the handbox to make adjustments. If you do move it manually 
or change the tripod position, the telescope has to be realigned.

Once you have aligned the telescope, you can slew to every object in the 
night sky. This is done by pressing the 

centre key (5)

 on the handbox and 

selecting the 

'Navigation'

 option from the menu.

Select the object catalogue you prefer from the menu by using the arrow 
keys. Press the centre key (5) to confirm your selection.

When you select an object catalogue, the first object of the catalogue will be 
displayed. You can change the currently displayed object by pressing the up 
and down arrow keys.

Select the object you want to view with the telescope by pressing the centre 
key (5). The telescope will then slew to that position.

Example: Let’s observe Jupiter.

Jupiter is visible in different parts of the world at different times depending on 
location, time of year and local conditions.

If it is visible from your location and the telescope is aligned, you can navi-
gate to Jupiter by following these steps. Press the centre key (5) on your 
handbox and select  the 

'Navigation'

 option. Move the selection bar with the 

arrow keys, then press the centre key (5) for confirmation. 

Next, select the 

'Solar System'

 menu option and scroll with the arrow keys 

to find Jupiter. Select 

Jupiter

 by pressing the centre key (5).

Once you select Jupiter, your telescope will automatically slew towards 
Jupiter. When the telescope reaches Jupiter's position, a loud beeping noise 
will let you know that the telescope is done moving. You may then begin your 
observation.

Possible observation targets

The following section details several interesting and easy-to-find celestial 
objects you may want to observe through your telescope.

The moon

The moon is Earth's only natural satellite.
Diameter: 3,476 

km

Distance: 

384,400 km from Earth (average)

The moon has been known to humans since prehistoric times. It is the sec-
ond brightest object in the sky, after the sun. Because the moon circles the 
Earth once per month, the angle between the Earth, the moon and the sun 
is constantly changing; one sees this change in the phases of the moon. 
The time between two consecutive new moon phases is about 29.5 days 
(709 hours).

Declination:

Distance:  

1,344 light years from Earth

Though it is more than 1,344 light years from Earth, the Orion Nebula 
(M 42) is the brightest diffuse nebula in the sky. It is visible even with the
