7. Install the Zenith mirror into the end of
the main scope tube.
8. Tighten the screws to fix the Zenith

Start using your Stargazer telescope
Practice during the day:
Please remove the lens dust protectors first and then fit the 25mm eyepiece, we
always recommend for first use, and practice to use the 25mm eyepiece. Point the
telescope using the finder-scope to a distant object. Twist the altitude control
handle (see fig.10a) to move the telescope up and down and unscrew the locking
dial (see fig. 10b) on the opposite side to move the telescope left to right. Once the
target is found twist the altitude control handle and tighten the the locking dial to
secure the telescope to your target.

It is important to practice this during daylight so that you get familiarised with the
telescope operation and how to secure the telescope into position when you have
chosen your target, practice makes perfect . A good target is a church tower,
distant tree, a chimney or a distant mountain peak if possible. Once locked into
position rotate the focuser dial so that the focuser tube moves in and out until you
find the best view possible, you may still need to adjust the telescope slightly if it
moves out of position of your chosen target, this is normal and adds to the
excitement and practice of finding your target perfectly. We suggest that you start
by rotating the focuser all the way in and slowly rotate it out until you find the
perfect view of your chosen object. Always practice first with the 25mm eyepiece.
Remember practice makes perfect.
NEVER LOOK DIRECTLY AT THE SUN THROUGH A TELESCOPE WITHOUT AN
OBJECTIVE SOLAR FILTER!
The Finder-scope:
The Finder-scope is a valuable part of the telescope when finding your chosen
object. Tooperate properly,the telescope and the finder-scope, should be aligned.
The chosen object through the finder-scope has a much broader field of view than
that of the telescope. Aligning your chosen image means matching the telescope’s
image as seen through the eyepiece to the chosen image at the centreof the
finder-scope. This way when looking through the finder-scope you know that the
telescope is pointing near exactly to the same point as the finder-scope. Thereis
nothing wrong with your finder scope if images appear upside down and reversed
left to right. This is a normal function of a finder-scope.
Barlow Lens:
The Barlow lens is a very interesting device. It is a negative lens that multiplies the
telescopes focal length. This unit is supplied with 1 piece Barlow Lens which offers
3 x Magnification. Meaning when using in conjunction with the 10mm or 25mm
eyepiece it will increase your magnification by 3 times. The barlow lens is fitted
between the Zenith mirror and the 10mm or 25mm eyepiece and usually best used
at night.
Zenith Mirror:
The Zenith Mirror is the right-angle prism or a plane mirror to reflect the rays from
an object near the zenith to the side of a refracting telescope for more convenient
observation.

Please Note: If you wear corrective lenses (specifically glasses) you may want to
remove them when observing with an eyepiece attached to the telescope. If you
have astigmatism then corrective lenses should be worn at all times.
Astronomer:
On your journey to becoming an established Astronomer it is important to study
readily available astronomy magazines or study the internet which will give you
valuable information, updates and the locations of the planets and best viewing
dates and times as they change position from month to month.
Observing Tips:
Try to view objects that are high in the sky if possible. Waiting until the object rises
well above the horizon will provide a brighter and crisper image. Objects on the
horizon are viewed through several layers of earth’s atmosphere. Ever wonder why
the moon appears orange as it sets on the horizon? It’s because you are looking
through a considerable more amount of atmosphere than you would directly
overhead. (Note: If objects high in the sky are distorted or wavy, you are probably
viewing on a very humid night and can be frustrating.) During nights of unstable
atmosphere and overcast conditions, viewing through a telescope can be
frustrating, if not impossible, at times. Astronomers refer to crisp, clear nights as
nights of "good viewing" and will study the internet and weather forecasts for the
perfect night.
The Eight Planets:
In our solar system thereare 8 planets, of which 4 will show some form of surface
details, being Mars, Saturn and Jupiter and of course our Moon. Study the internet
regularly for best viewing dates when these planets will be at their best for viewing.
Our moon is the easiest observing target. It will always look approximately the
same through low magnification as any telescope. But larger instruments will allow
you to zoom in to reveal the real beauty of our moon, showing the craters and
mountains. Study when the moon will be at the largest and clear sky's for the best
results. Jupiter and Saturn are next. Saturn's rings can be seen by all but the
smallest telescopes (except when the rings areedge on). It is also possible to see
bands within Jupiter's atmosphere. Mars can be seen on a good night and will
show the largest and most prominent features on the Martian surface, although the
image will be very small and the resolution too low to reveal much detail.

Troubleshooting and frequently asked questions
Q: I can’t get to focus my telescope, only get a bright circle.
A: Make sure you have inserted the diagonal Zenith mirror and an eyepiece
(start by the lowest power eyepiece – 25mm).
Q: I use the finder-scope to point to objects but I always miss the
target.
A: You probably need to realign the finder-scope on the target if you accidentally
nudge the telescope. After and learning how to tighten the telescope into
position of the target you will find you improve on this.
Q: When I use the barlow lens and the 10mm eyepiece the image
is so dark I can’t hardly see anything.
A: It depends on how stable the atmosphere is, too much turbulence causes
image distortion. The more magnified the image is the darker it gets.
Q: The stars only appear as points in the telescope, is this normal?
A: This is normal. Stars will always appear only as points, even in the largest
telescopes in the world. It is more interesting for beginners to observe two-
dimensional objects, such the moon or planets. Once you find these, you will
be able to start learning about the astronomical calendar.
Q: I would like to observe the Sun. How can I do it?
A: An appropriate specialist solar filter, placed over the objective, is essential for
observing the sun. These are available as plastic foil or glass filters (not
supplied by us). They allow only a tiny and harmless fraction of sunlight into the
telescope’s aperture. When securely positioned over the objective, they allow
observation of the sun in complete safety. Eyepiece solar filters should be
avoided at all costs as they are considered unsafe.
NOTE: NEVER LOOK DIRECTLY ATTHE SUN THROUGH A TELESCOPE
WITHOUT AN OBJECTIVE SOLAR FILTER!
Q: Ican’t see anything when I look through my telescope.
Did I do something wrong?
A: Check you have removed all the lens dust caps. All Telescopes are only suitable
for astronomical observing and when used outside at night when the sky is
clear is when you achieve the best results. Observing from inside a house
through a window or during the day is not usually best practice unless
practising and learning how to use the telescope.

Cleaning and Storage:
Agood storage place should be dry, dust-free, secure, and large enough to get the
telescope in and out easily. Ideally, store the telescope in its storage bag when not
in use. Always fit the lens covers when not in use.
For Basic Cleaning:
1. Use suitable compressed air to blow off loose dust and large particles.
2. Use a lens cleaning solution for telescope lenses to gently lift off any remaining
dirt or smudges.
3. Use the solution to wet soft, plain tissue or cotton balls for larger optical surfaces
or cotton swabs for small parts like eyepiece lenses.
4. Make sure the lens protection caps are fitted and gently wipe the body over with
asoft cloth.
