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 navigate
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 second
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 con-
stantly 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).
Constellation Orion: The Orion Nebula (M 42)
Right Ascension:
05

35
m
(hours : minutes)
Declination:
-05° 22' (Degrees : minutes)
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 naked eye and
a worthwhile object for telescopes of all types and sizes. The nebula consists
of a gigantic cloud of hydrogen gas with a diameter of hundreds of light years.
