2. Assembly

1. Attach the three aluminum tripod legs (A) to the yoke

mount (B) (Figure 3a) with the three hinged leg brac-

es facing inward. Three hex-head bolts (C) each about

3" long, with 5/8" washers (C) and wing nuts (shown in
Figure 1 attached to the bolts), are provided for this
purpose. Note that the bolts should be inserted from the

side of the leg that has the hex-shaped hole, so that the
bolt head seats in the hex-shaped hole (Figure 3b). The

washer then the wing nut are placed on the opposite side
on the exposed end of the bolt.

2. Attach a leg lock thumbscrew (D) to each leg as shown

(Figure 4). Extend the sliding inner portion of the adjust-
able-height tripod leg to the desired length for all three

legs. Lock in place by tightening the leg lock thumbscrews.

Do not over-tighten the leg lock thumbscrews or you
may damage the collar they are attached to.

3. Now stand the tripod upright, spreading the legs evenly
apart so the accessory tray can be positioned to attach to
the three leg braces.

4. Attach the accessory tray (E) to the leg brace supports
(Figure 5) with the three short screws (F), small (3/8”)
washers, and small wing nuts provided (washers and
wing hunts shown attached to the screws in figure 1).
Place a washer on the screw. Then place the accessory
tray on top of one of the leg braces so that the mounting
screw passes through the hole at one of the corners of
the accessory tray, and through the slot in the leg brace.
Then place another small washer on the screw and thread
on and tighten the wing nut. You may find it helpful to use
the supplied screwdriver tool (O) to hold the screw heads
while tightening the wingnuts. Repeat this procedure until
the tray is attached to all three leg braces.

The tripod and yoke mount are now fully assembled (Figure

6). Next you will install the telescope tube on the altazimuth

yoke mount.

5. With the optical tube (G) oriented relative to the yoke
mount (B) as shown in Figure 7, line up the holes in the
attachment plates on the side of the optical tube with the
holes in the ends of the yoke mount (7a). Then secure
the optical tube to the mount by inserting a yoke knob (H)
through the hole on each side of the yoke and thread them
into the attachment plates on the optical tube (7b). They
should be reasonably tight but still allow movement of the
telescope up and down with gentle force.

6. Insert the altitude micro-motion rod (I) through the hole in

the metal receptacle on the yoke mount (Figure 8a). You
may have to unthread the altitude lock knob a few turns to
provide clearance for the rod). Then attach the other end
of the rod to the metal anchor cylinder using the anchor
screw (J) provided (Figure 8b). Use the supplied screw­driver tool (O) to tighten the screw.

Finally, you will install a few accessories, then you’ll be ready

to observe!

7. To attach the red dot finder scope (K) to the optical tube,

orient the finder scope as shown in Figure 9 and slide
the bracket foot into the finder scope base until it clicks.
(To remove the finder scope, press the small tab at the
back of the base and slide the bracket out.)

8. Insert the star diagonal (L) into the focuser drawtube and

tighten the thumbscrew on the drawtube collar (Figure

10). Then insert the 25mm eyepiece (M) into the diagonal

Aligning and Using the Red Dot Finder Scope

The included red dot finder scope (Figure 11) makes point­ing your telescope almost as easy as pointing your finger! It’s a
non-magnifying aiming device that superimposes a tiny LED red

dot on the sky, showing exactly where the telescope is pointed.

It permits easy object targeting prior to observation in the higher-

power main telescope.

Before you can use the red dot finder scope, you must remove
the small plastic tab sticking out from the battery compartment

(Figure 11). Doing so will allow the pre-installed 3V CR-2032
button cell battery to make contact with the finder scope’s elec­tronic circuitry to power the finder’s red LED illuminator. The tab

can then be discarded.

To use the red dot finder scope properly, it must be aligned with
the main telescope. This is easiest to do during daylight hours,
before observing at night. Follow this procedure:

1. First, remove the dust cap (P) from the front of the tele­scope.

2. Then, with the 25mm eyepiece already in the focuser from

step 8 above, point the telescope at a well-defined land
target (e.g., the top of a telephone pole) that’s at least a

quarter mile away. When pointing the telescope, be sure

to loosen the azimuth lock knob and micro-motion lock

knob (for coarse movement in altitude) to allow the tele­scope to rotate freely about both axes.

3. Center the target in the eyepiece

the holes in the tube’s attachment plates with those in the yoke

mount. b) Thread the yoke knob into the threaded hole in the
attachment plates.

4. Now that a distant target is centered in the main tele-

scope’s eyepiece, turn on the red dot finder scope by slid-

ing the power switch to ON (refer to Figure 11). The “1”
position provides dim illumination while the “2” position
provides brighter illumination. Typically the dimmer setting
is used under dark skies and the brighter setting is used

under light-polluted skies or in daylight. Position your eye

at a comfortable distance from the rear of the unit. Look
through the rear of the finder scope with both eyes open
to see the illuminated red dot. The target object should
appear in the field of view somewhere near the red dot.

5. You’ll want to center the target object on the red dot.

To do so, without moving the telescope, use the finder

scope’s vertical and horizontal adjustment knobs (shown

in Figure 11) to position the red dot on the object.

6. When the red dot is centered on the distant object, check

to make sure the object is still centered in the telescope’s
eyepiece. If it isn’t, re-center it then adjust the finder
scope’s alignment again. When the object is centered in
the telescope eyepiece and on the finder scope’s red dot,

the finder scope is properly aligned with the telescope.

The red dot finder scope’s alignment should be checked

before every observing session.

At the end of your observing session, be sure to slide the power
switch on the red dot finder scope to OFF to preserve battery life.

Understanding the “Altazimuth” Mount

The Observer II 70mm Altazimuth refractor features an “altaz­imuth” mount, which permits motion along two perpendicular
axes: altitude (up/down) and azimuth (left/right) (see Figure

2). This makes pointing the telescope easy and intuitive. To
move the telescope in the azimuth direction, loosen the azimuth
lock knob, take hold of the telescope and gently rotate it to the

desired position. Then re-tighten the azimuth lock knob. To move

the telescope in the altitude direction, loosen the altitude lock
knob then move the tube up or down to the desired position.
Then retighten the altitude lock knob. If the telescope moves too
freely in the in the altitude direction, then tighten up the yoke
knobs a bit. Of course, you can move the telescope in altitude
and azimuth simultaneously by loosening both of the lock knobs.

Because making fine-adjustments in the altitude of the tele-

scope can be difficult, the Observer II 70mm Altazimuth refractor

comes equipped with an altitude micro-motion rod and thumb-

wheel (Figure 12). After making coarse altitude adjustments
by moving the tube by hand, you can then move the telescope

incrementally by turning the micro-motion rod’s thumbwheel (the

altitude lock knob must be tightened for this). The telescope will
move a very small amount either up or down, depending on
which direction you turn the thumbwheel. Fine motion can be
helpful when centering an object in the eyepiece.

Choosing an Observing Site

When selecting a location for observing, get as far away as pos­sible from direct artificial light such as street lights, porch lights,
and automobile headlights. The glare from these lights will great-

ly impair your dark-adapted night vision. Set up on a grass or

dirt surface, not asphalt, because asphalt radiates more heat.
Heat disturbs the surrounding air and degrades the images seen
through the telescope. Avoid viewing over rooftops and chim­neys, as they often have warm air currents rising from them.
Similarly, avoid observing from indoors through an open (or
closed) window, because the temperature difference between
the indoor and outdoor air will cause image blurring and distor­tion.

If at all possible, escape the light-polluted city sky and head for
darker country skies. You’ll be amazed at how many more stars
and deep-sky objects are visible in a dark sky!

“Seeing” and Transparency

Atmospheric conditions vary significantly from night to night.

“Seeing” refers to the steadiness of the Earth’s atmosphere

at a given time. In conditions of poor seeing, atmospheric
turbulence causes objects viewed through the telescope to
“boil.” If you look up at the sky and stars are twinkling notice­ably, the seeing is poor and you will be limited to viewing at
lower magnifications. At higher magnifications, images will
not focus clearly. Fine details on the planets and Moon will
likely not be visible.

In conditions of good seeing, star twinkling is minimal and
images appear steady in the eyepiece. Seeing is best over­head, worst at the horizon. Also, seeing generally gets better
after midnight, when much of the heat absorbed by the Earth
during the day has radiated off into space.

Especially important for observing faint objects is good “trans­parency”—air free of moisture, smoke, and dust. All tend to scat-

ter light, which reduces an object’s brightness. Transparency is

judged by the magnitude of the faintest stars you can see with
the unaided eye (5th or 6th magnitude is desirable).

Cooling the Telescope

All optical instruments need time to reach “thermal equilibri­um.” The bigger the instrument and the larger the temperature
change, the more time is needed. Allow at least 30 minutes for
your telescope to acclimate to the temperature outdoors before
you start observing with it.

Let Your Eyes Dark-Adapt

Don’t expect to go from a lighted house into the darkness of the

outdoors at night and immediately see faint nebulas, galaxies,
and star clusters—or even very many stars, for that matter. Your
eyes take about 30 minutes to reach perhaps 80% of their full

dark-adapted sensitivity. As your eyes become dark-adapted,
more stars will glimmer into view and you’ll be able to see fainter

details in objects you view in your telescope.

7

To see what you’re doing in the darkness, use a red-filtered

flashlight rather than a white light. Red light does not spoil your

eyes’ dark adaptation like white light does. A flashlight with a red

LED light is ideal. Beware, too, that nearby porch, streetlights,
and car headlights will ruin your night vision.

Eyepiece Selection

Magnification, or power, is determined by the focal length of
the telescope and the focal length of the eyepiece being used.
Therefore, by using eyepieces of different focal lengths, the
resultant magnification can be varied. It is quite common for an
observer to own five or more eyepieces to access a wide range
of magnifications. This allows the observer to choose the best
eyepiece to use depending on the object being viewed and
viewing conditions. Your Observer II 70mm Altazimuth refrac­tor comes with 25mm and 10mm Kellner eyepieces, which will
suffice nicely to begin with. You can purchase additional eye­pieces later if you wish to have more magnification options.

Magnification is calculated as follows:

Telescope Focal Length (mm)

=
Magnification

Eyepiece Focal Length (mm)

For example, the Observer II 70mm Altazimuth has a focal
length of 700mm, which when used with the supplied 25mm
eyepiece yields:

700 mm

= 28x

25 mm

The magnification provided by the 10mm eyepiece is:

700 mm

= 70x

10 mm

The maximum attainable magnification for a telescope is directly
related to how much light it can gather. The larger the aperture,
the more magnification is possible. In general, a figure of 50x per
inch of aperture is the maximum attainable for most telescopes.
Going beyond that will yield simply blurry, unsatisfactory views.

Figure 13. The Kellner eyepieces have barrels threaded to
accept optional Orion 1.25" filters. A Moon filter is useful for cut­ting glare and revealing more detail on the lunar surface.

Your Observer II 70mm Altazimuth has an aperture of 70mm,
or 2.8 inches, so the maximum magnification would be about
140x (2.8 x 50). This level of magnification assumes you have
ideal atmospheric conditions for observing (which is seldom the
case).

Keep in mind that as you increase magnification, the brightness
of the object viewed will decrease; this is an inherent principle
of the laws of physics and cannot be avoided. If magnification is
doubled, an image appears four times dimmer. If magnification
is tripled, image brightness is reduced by a factor of nine!

So start by using the 25mm eyepiece, then try switching to the
10mm eyepiece later if you want to boost the magnification.

Focusing the Telescope

To focus the telescope, turn the focus wheels (Figure 10)
forward or back until you see your target object (e.g., stars,
the Moon, etc.) in the eyepiece. Then make finer adjustments

until the image is sharp. If you’re having trouble achieving ini-

tial focus, rack the focuser drawtube all the way in using the
focus wheels, then while looking into the eyepiece slowly turn
the focus wheels so that the drawtube extends outward. Keep
going until you see your target object come into focus. Note
that when you change eyepieces you may have to adjust the
focus a bit to get a sharp image with the newly inserted eye­piece.

What to Expect

So what will you see with your telescope? You should be able to
see bands on Jupiter, the rings of Saturn, craters on the Moon,

the waxing and waning of Venus, and many bright deep-sky

objects. Do not expect to see color as you do in NASA photos,

since those are taken with long-exposure cameras and have

“false color” added. Our eyes are not sensitive enough to see

color in deep-sky objects except in a few of the brightest ones.

Objects to Observe

Now that you are all set up and ready to go, one critical decision
must be made: what to look at?

A. The Moon

With its rocky surface, the Moon is one of the easiest and most
interesting objects to view with your telescope. Lunar craters,
maria, and even mountain ranges can all be clearly seen from a

distance of 238,000 miles away! With its ever-changing phases,
you’ll get a new view of the Moon every night. The best time

to observe our one and only natural satellite is during a partial
phase, that is, when the Moon is not full. During partial phas­es, shadows are cast on the surface, which reveal more detail,
especially right along the border between the dark and light por­tions of the disk (called the “terminator”). A full Moon is too bright
and devoid of surface shadows to yield a pleasing view. Make
sure to observe the Moon when it is well above the horizon to
get the sharpest images.

Use an optional Moon filter to dim the Moon when it is very
bright. It simply threads onto the bottom of the eyepieces (you
must first remove the eyepiece from the focuser to attach a fil-

ter). You’ll find that the Moon filter improves viewing comfort, and

helps to bring out subtle features on the lunar surface.

8

B. The Planets

The planets don’t stay put like the stars, so to find them you

should refer to the monthly star charts at OrionTelescopes.
com, or to charts published monthly in Astronomy, Sky &

Telescope, or other astronomy magazines. Venus, Mars,

Jupiter, and Saturn are the brightest objects in the sky after the
Sun and the Moon. Other planets may be visible but will likely

appear star-like. Because planets are quite small in apparent
size, optional higher-power eyepieces or a Barlow lens are

recommended and often needed for detailed observations.

B. The Sun

You can change your nighttime telescope into a daytime Sun

viewer by installing an optional full-aperture solar filter over the

front opening of the telescope. The primary attraction is sun­spots, which change shape, appearance, and location daily.
Sunspots are directly related to magnetic activity in the Sun.
Many observers like to make drawings of sunspots to monitor
how the Sun is changing from day to day.

Important Note: Do not look at the Sun with any optical
instrument without a professionally made solar filter, or per­manent eye damage could result.

D. The Stars

Stars will appear like twinkling points of light. Even powerful
telescopes cannot magnify stars to appear as more than a
point of light. You can, however, enjoy the different colors of
the stars and locate many pretty double and multiple stars.

The famous “Double-Double” in the constellation Lyra and the
gorgeous two-color double star Albireo in Cygnus are favor-

ites. Defocusing a star slightly can help bring out its color.

E. Deep-Sky Objects

Under dark skies, you can observe a wealth of fascinating

deep-sky objects, including gaseous nebulas, open and glob­ular star clusters, and different types of galaxies. Most deep-

sky objects are very faint, so it is important you find an observ­ing site well away from light pollution.

To find deep-sky objects with your telescope, you first need

to become reasonably familiar with the night sky. Unless you
know how to recognize the constellation Orion, for instance,

you won’t have much luck locating the Orion Nebula. A simple

planisphere, or star wheel, can be a valuable tool for learning
the constellations and seeing which ones are visible in the sky
on a given night. Once you have identified a few constella­tions, a good star chart, atlas, or astronomy app will come in

handy for helping locate interesting deep-sky objects to view

within the constellations.

Do not expect these objects to appear like the photographs
you see in books and on the internet; most will look like dim
gray smudges. Our eyes are not sensitive enough to see color

in deep-sky objects except in a few of the brightest ones. But

as you become more experienced and your observing skills
get sharper, you will be able to ferret out more and more subtle
details and structure.

5. Worthwhile Optional
Accessories

• Moon Filter – A 1.25" Moon filter will cut down the strong

glare of sunlight reflected from the Moon, making Moon
viewing more comfortable and revealing more surface
detail. The filter threads into the bottom of the Kellner eye­pieces that came with your telescope (Figure 13).

• Barlow Lens – A 2x Barlow lens doubles the magnify-

ing power of any eyepiece it’s used with, giving you a big

power boost to get in closer to your target object. You just
insert it between the diagonal and the eyepiece.

• Correct-Image Diagonal – Also called an “erect-

image” diagonal, this accessory will provide a correctly ori­ented view through the telescope, which is recommended
for daytime terrestrial viewing.

• Planisphere – A nifty “star wheel” that shows what stars

and constellations are visible in the sky at any time of any
night. Just set the date and time see a mini representation
of your local night sky. Great for identifying what you see

and planning an evening’s observing session.

• Star Map – More detailed than a planisphere, a star

map is essential for locating interesting celestial objects
to observe with your telescope. Nowadays many mobile
astronomy apps feature customizable star maps that you

can access on your smartphone or tablet while you’re at

the telescope.

6. Telescope Care and
Maintenance

If you give your telescope reasonable care, it will last a lifetime.

Store it in a clean, dry, dust-free place, safe from rapid changes in

temperature and humidity. Do not store the telescope outdoors,
although storage in a garage or shed is OK. Small components
like eyepieces and other accessories should be kept in a protec­tive box or storage case. Keep the dust cover on the front of the
telescope when it is not in use.

Your refractor telescope requires very little mechanical mainte­nance. The optical tube has a smooth painted finish that is fairly

scratch-resistant. If a scratch does appear on the tube, it will not
harm the telescope. If you wish, you may apply some auto touch-

up paint to the scratch. Smudges on the tube can be wiped off
with a soft cloth and household cleaning fluid.

Cleaning Optics

Any quality optical lens cleaning tissue and optical lens clean­ing fluid specifically designed for multi-coated optics can be used

to clean the lenses of your telescope and eyepieces. Never use
regular glass cleaner or cleaning fluid designed for eyeglasses.
Before cleaning, remove any loose particles or dust from the lens
with a blower bulb or soft brush. Then apply some cleaning fluid
to a tissue, never directly on the optics. Wipe the lens gently in
a circular motion, then remove any excess fluid with a fresh lens
tissue. Oily fingerprints and smudges may be removed using this
method. Use caution; rubbing too hard may scratch the lens. On

9

larger lenses, clean only a small area at a time, using a fresh
lens tissue on each area. Never reuse tissues.

When bringing the telescope inside after an evening’s viewing

it is normal for moisture to accumulate on the lenses due to the
change in temperature. We suggest leaving the telescope and
eyepieces uncovered overnight to allow the condensation to
evaporate.
