Telescope Terms To Know:
Diagonal: A mirror that deflects the ray of light 90 degrees.
With a horizontal telescope tube, this device deflects the light upwards so
that you can comfortably observe by looking downwards into the eyepiece.
The image in a diagonal mirror appears upright, but rotated around its
vertical axis (mirror image).
Focal length: Everything that magnifies an object via an optic lens has a certain focal length. The focal length is the
length of the path the light travels from the surface of the lens to its focal point. The focal point is also referred to as the
focus. In focus, the image is clear. In the case of a telescope, the focal length of the telescope tube and the eyepieces
are used to determine magnification.
Lens: The lens turns the light that falls on it around in such a way so that the light gives a clear image in the focal point
after it has traveled a certain distance (focal length).
Eyepiece: An eyepiece is a system made for your eye and comprised of one or more lenses. In an eyepiece, the clear
image that is generated in the focal point of a lens is captured and magnified still more.
Magnification: The magnification corresponds to the difference between observation with the naked eye and
observation through a magnifying device like a telescope. If a telescope configuration has a magnification of 30x, then
an object viewed through the telescope will appear 30 times larger than it would with the naked eye. To calculate the
magnification of your telescope setup, divide the focal length of the telescope tube by the focal length of the eyepiece.

Using/Aligning the Red Dot Viewfinder:
The viewfinder is powered by a CR-2032 battery that is included. Before using the viewfinder for the first time,
remember to remove the plastic insulator that is blocking the battery from connecting.
For The Viewfinder To Be Effective, It Must Be Aligned. To do this:
• Insert the 26 mm eyepiece into
the diagonal and power on the
viewfinder by sliding the switch
on its right side to an “On”
position.
• Point the eyepiece at an easy to
identify target like a telephone
pole that is approximately 200
yards away. Center the object in
the eyepiece. Lock the telescope
into place by tightening the
locating screws on both the
altitude fine adjustment and the
altitude axis (Fig 1, #9 & Fig 2,
#10).
• Without moving the telescope,
position the red dot using the
two adjustment screws so that it
shares the same view as the one
in your eyepiece. The front screw
will move the viewfinder up and
down, and the other will move it
side to side. Your viewfinder is
now aligned.
Note: To preserve battery life, don’t
forget to turn off the viewfinder
after use.
Using your telescope:
After you have aligned your viewfinder, you are ready to start observing! Put the 26 mm eyepiece into the diagonal to
get the widest field of view. This wider field of view will make it easier to locate and track objects. Loosen the locating
screws for the altitude fine adjustment and the altitude axis to move the scope up, down and side to side until your
target comes into view in the eyepiece. When you have the object well placed in the eyepiece, you can re-tighten the
locating screws and fix the position of the telescope (Fig 1, #9 & Fig 2, #10).
It is important to remember that the rotation of the Earth means objects will move out of your eyepiece fairly quickly.
Once you have found and focused on your desired target, you can track it as it journeys across the night sky using the
panhandle.
For a closer look at an object, you can insert the 9.7 mm eyepiece. The magnification will increase from 27x to 72x.
For a more closer look at an object, you can insert the 2x Barlow lens. The magnification will increase to 54x for the
26 mm eyepiece and 144x for the 9.7 mm eyepiece.
Cleaning:
Your telescope is a precision optical device and keeping the optics free of dust and dirt is crucial for optimal
performance. To clean the lenses (objective and eyepiece) use only a photo-grade soft brush or a lint-free cloth, like a
microfiber cloth. Do not press down too hard while cleaning, as this might scratch the lens. Ask your parents to help if
your telescope is really dirty, if necessary, the cleaning cloth can be moistened with an optical glass cleaning fluid and
the lens wiped clean using very little pressure. Do not use harsh detergents!
Make sure your telescope is always protected against dust and dirt.
After use, leave it in a warm room to dry off before storing.

Terrestrial Images
Possible Objects for Observation:
Terrestrial objects
Take note of the examples below, including Mount Rushmore and the golf course.
Start with the 26 mm eyepiece and focus until the image is clear. After mastering
the 26 mm eyepiece, switch to the 9.7 mm eyepiece and practice scanning and
focusing until the image is clear. Choose several terrestrial objects to practice
focusing on, but never point your telescope at or near the sun, or you risk blindness.
The Moon
Diameter: 3,476 km
Distance: Approximately 384,401 km
The Moon is the Earth’s only natural satellite, and it is the second brightest object in
the sky (after the Sun). Although it is our closest neighbor, a lot of people have never
really taken a good long like at the Moon. With your telescope, you should be able to
see several interesting lunar features. These include lunar maria, which appear as
vast plains, and some of the larger craters. The best views will be found along the
terminator, which is the edge where the visible and cloaked portions of the Moon meet.
Orion Nebula (M 42)
M 42 in the Orion constellation
Right ascension: 05:35 (Hours: Minutes)
Declination: -5:22 (Degrees: Minutes)
Distance from Earth: 1,500 light years
Located about 1,500 light years from Earth, the Orion Nebula (Messier 42,
abbreviation: M 42) is the brightest diffuse nebula in the sky – visible with the naked
eye, and a worthwhile object for telescopes of all types and sizes, from the smallest
field glass to the largest earthbound observatories and the Hubble Space Telescope.
When talking about Orion, we‘re actually referring to the main part of a much larger
cloud of hydrogen gas and dust, which spreads out over half of the Orion constellation.
The expanse of this enormous cloud stretches several hundred light years.
Ring Nebula (M 57)
M 57 in the Lyra constellation
Right ascension: 18:53 (Hours: Minutes)
Declination: -33:02 (Degrees: Minutes)
Distance from Earth: 2,400 light years
The famous Ring Nebula M 57 in the constellation of Lyra is often viewed as the
prototype of a planetary nebula; it is one of the magnificent features of the Northern
Hemisphere’s summer sky. Recent studies have shown that it is probably comprised
of a ring (torus) of brightly shining material that surrounds the central star (only
visible with larger telescopes), and not of a gas structure in the form of a sphere or
an ellipsis. If you were to look at the Ring Nebula from the side, it would look like the
Dumbbell Nebula (M27). When viewed from Earth, we are looking directly at the pole
of the nebula.
Dumbbell Nebula (M 27)
M 27 in the Fox constellation
Right ascension: 19:59.6 (Hours: Minutes)
Declination: -+22:43 (Degrees: Minutes)
Distance from Earth: 1,360 light years
The Dumbbell Nebula (M 27) in Fox was the first planetary nebula ever discovered. On
July 12, 1764, Charles Messier discovered this new and fascinating class of objects. We
see this nebula almost directly from its equatorial plane. If we could see the Dumbbell
Nebula from one of its poles, we would see the shape of a ring, and we would see
something very similar to what we know as the Ring Nebula (M 57). In reasonably good
weather, we can see this object well even with low magnifications.

Troubleshooting Guide:
Problem Solution
No picture Remove dust protection cap and sun-shield from the
objective opening.
Blurred picture Adjust focus using focus ring.
No focus possible Wait for temperature to balance out.
Bad quality Never observe through a glass surface such as a window.
Viewing object visible in the finder, but
not through the telescope Align finder to telescope (see instructions)
Despite using star diagonal prism the
picture is “crooked”
The star diagonal prism should be vertical in the eyepiece
connection.
