When you select an object catalog, the first object of the catalog 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 center key (22). 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 navigate to Jupiter by following these steps.
Press the center key (22) on your handbox and select the ‘Navigation’ option. Move the selection bar with the arrow
keys, then press the center key (22) for confirmation.
Next, select the ‘Solar System’ menu option and scroll with the arrow keys to find Jupiter. Select Jupiter by pressing
the center key (22).
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.
Formula for calculating magnification:
Focal length (Telescope) ÷ Focal length (Eyepiece) = Magnification
Examples:
350 mm
÷
20 mm
=
17.5x
350 mm
÷
10 mm
=
35x
1250 mm
÷
25 mm
=
50x
1250 mm
÷
12.5 mm
=
100x
