USING YOUR TELESCOPE
WARNING
NEVER USE AN INSTRUMENT TO LOOK DIRECTLY AT THE SUN.
LOOKING DIRECTLY AT THE SUN, OR IN ITS IMMEDIATE SURROUNDING AREA,
WILL CAUSE IMMEDIATE AND IRREVERSIBLE DAMAGE TO YOUR SIGHT. SIGHT
DAMAGE DOES NOT GENERALLY CAUSE ANY PAIN, AND THE OBSERVER WILL HAVE
NO WARNING UNTIL IT IS TOO LATE. NEVER POINT THE INSTRUMENT, OR THE
FINDERSCOPE, DIRECTLY AT OR IN THE SURROUNDING AREA OF THE SUN. DO
NOT LOOK IN THE EYEPIECE OR THE FINDERSCOPE WHEN THE INSTRUMENT IS
MOVING. ANY USE BY CHILDREN MUST BE SUPERVISED BY AN ADULT.
Once the telescope has been set up, the finderscope set and the poles aligned, you are ready to start
your observations.
Your telescope will allow you to carry out two types of observations:
Planetary observations:
The Moon, Mercury, Venus, Mars, Jupiter, Saturn.
Deep sky observations:
Galaxies, Nebulae.
Note: it will not be of any particular interest to observe a star. Essentially, stars are so far away that
when seen through a telescope, they look like a simple dot!
For your first observation, choose something easy to see: The Moon to help you get used to how the
telescope works and how to use it.
To achieve the best results during your observations, heed the following advice:
Warning: During all observations, your telescope must remain aligned, so you can benefit from the
advantages of the equatorial mount.
In order to move the optical tube towards an object to be observed, you simply need to unscrew the
two brakes (RA) and (Dec) so that the telescope can turn freely, while the right ascension axis conti-
nues to point to the North star.
Once an object becomes visible in the instrument's field of view, you will simply need to slowly turn
the right ascension knob (12) to offset the rotation of the Earth throughout the observation.
• To centre an object in the telescope, first use the finderscope to locate the object that you wish to
observe. Once the object is centred in the reticle of the finderscope, it will appear in the eyepiece of
the instrument. (If this is not the case, it means that the finderscope is not set: see how to adjust the
finderscope) tighten the two brakes (RA) and (Dec).
• Always start an observation with a low-powered eyepiece (for example, eyepiece K 25mm)
• Once the object has been centred, you can align the poles by turning the buttons on the eyepiece
holder (20). You will note that the celestial body observed starts to slowly move within the field of
