1. Introduction
Important Points About Your New Telescope
Take the time to read this instruction manual thoroughly, so that you may gain
the maximum benefits from your new telescope!
1. Never look at the sun without the proper, professionally made full aperture
filtration system. You can be permanently blinded by concentrated sunlight. Never use a dark-glass screw-in eyepiece filter; it may crack under
intense heat.
2. Like all telescopes, performance is best after the telescope has cooled to outside temperatures for at least 30 minutes (longer in colder climates). Better yet,
store it cold. Use only low powers until your scope has equalized.
3. Observe from a dark location, away from street and porch lights. Your eyes
take 10 to 30 minutes to reach maximum sensitivity. Use a red filtered flashlight; a white light can seriously reduce your low-light sensitivity.
4. Keep your telescope’s optics in good condition for maximum performance.
You should use a blower bulb (not canned air) to remove dust and other bits
of debris prior to and after each use.
5. You should not have to lubricate the gears on the mount; this has been done
at the factory. However, after long periods of storage, or a visit to a particularly dusty observing site, you may want to put a light coating of automotive
bearing grease on the gears.
DANGER
Do Not Look At the Sun
With Your Telescope!
Never, ever, look directly at the
sun with your telescope without a
professional solar filter which
completely covers the front of the
telescope! Permanent eye damage may result from looking at
the sun for even an instant. Young
children should only use this
telescope with adult supervision.

2. Terminology
Optical Tube The main body of the telescope, holding the optics.
Objective Lens Gathers light and brings it to a focus.
Rack and Pinion Focuser The mechanical holder for the eyepiece, which
allows the eyepiece to be moved in and out to
adjust the focus of the telescope.
Eyepiece The part into which you look. It has a number of
lenses which magnify and allow your eye to focus
on the image formed by the telescope. Two eyepieces are supplied with the telescope. You can buy
additional eyepieces; eyepieces of different focal
lengths will produce different magnification factors.
Equatorial Mount The equatorial mount allows for the telescope's
axes of rotation to be adjusted to the user's
latitude. The overall effect is that the observer
can track the heavens along the path of the
Earth’s rotation.
Finder Scope Aids in pointing the telescope. It is a small, low-
power telescope with ”cross hairs“ that attach to
the optical tube. Its wide field of view greatly
reduces the work of finding a faint object in the
main eyepiece of the telescope.

cradle rings, but not so tight that the optical tube is dented.
The telescope is now a complete unit, ready for first light. However, there is one
additional step that should be done prior to taking your SkyView out for the first
time: aligning the finder scope.
Aligning the Finder Scope
Having a finder scope makes it very easy to locate objects in the night sky. You
may be looking for an object with your naked eye and not see a thing, but the use
of a properly aligned finder scope can put that object right in the center of your
telescope’s eyepiece.
After mounting the finder scope, you will want to align the finder to the main
telescope . . . to have them both pointing at the same object. This is best done
during the daylight hours so that you know the image is the same in the finder
scope and telescope. Choose a tree, telephone pole, street sign, anything that is
roughly one-fourth to one-half mile away, the further the better. Put that image
in the center of the field of your telescope’s eyepiece. Where is it in your finder
scope’s eyepiece? Hopefully the image will be in the field of view and some
simple adjustments on the alignment screws of the mounting bracket will put the
image dead center in the cross hairs. By loosening one of the alignment screws,
and tightening another one, you are changing the line of sight of the finder scope.
Continue making adjustments to the various alignment screws until the image in
the finder scope matches exactly the image in the telescope’s eyepiece. Check the
alignment by moving the scope to another object and fixing the cross hairs on the
exact point you want to look at. Then look through the telescope’s eyepiece to see
if the images are the same. If they are, the job is done. If not, make the necessary
adjustments until the two images match up.
Finder scopes often come out of alignment during transportation from site to site.
Make the necessary adjustments to the alignment screws to bring the image back
into the center of the cross hairs. Check to see that the same image is in your
telescope’s eyepiece. One way to help minimize any misalignment is to keep the
finder-to-main tube bolts very tight.
5. Using Your Telescope
Moving the Telescope
The telescope is easy to take wherever you want to do your observing. You’ll be
amazed at the difference in views from the city lights to the dark country skies.
(The moon and planets aren’t affected much by city lights, however.)
Don’t be afraid to load the telescope into your car for a trip to the hills. Common
sense prevails: as long as the telescope doesn’t roll or bounce around, you won’t
hurt it at all by moving it. Naturally, you should be careful not to damage any
6
4. Getting Started
Unpacking Your Telescope
The SkyView comes almost completely assembled from the factory. For ease of
transportation, it is broken down into several main parts: the tube, the mount,
and the tripod. Compare the diagram of accessories to the box you have just
opened and identify all the parts. Make sure that all the items listed are present.
Please be sure to keep the original shipping container intact. Not only would it
be needed in the event of shipping the telescope to another location, or back to
Orion for warranty repair service, but it also makes a very good storage container when the telescope is not in use.
Assembling the Tripod and Mount
The tripod and equatorial head come pre-assembled
from the factory. Your first step will be to attach the
accessory tray to the center of the leg supports; it
attaches from the bottom with the knob that has been
included. Next you will want to thread the counterweight shaft into the equatorial head along the
declination axis. Slide the counterweight onto the
shaft and thread in the counterweight stop at the end
of the shaft. The final step in completing the tripod
and mount assembly is to attach the two slow motion
control cables. They attach to either side (whichever is
most comfortable for you) of the shafts extending from the worm gears on the RA
and DEC axes.
Optical Tube Preparation
The optical tube is pretty much complete. The optics have been installed at the
factory and there is no need to do any adjustments to them. However, you will
need to install the finder scope.
Locate the finder scope from the items in the shipping container. The bracket has
already been installed onto the OTA; you will need to install the finder scope into
the bracket. Back out the adjustment screws until the tip is flush with the
bracket, insert the finder scope, and tighten the adjustment screws. To start, you
will want to have the finder scope floating in the middle of the rings. For further
adjustment, see Aligning the Finder Scope.
Optical Tube into the Cradle Rings
Attaching the optical tube to the tripod and mount assembly is done with tube
clamps. These clamps are bolted to the equatorial mount at the head of the declination axis with the included knobs. By unthreading the knobs on the ringed
portion of the cradle, the clamps will swing open and the optical tube will
securely fit inside. Thread the knobs so that the tube does not slide while in the

can easily be kept within the telescope’s field of view.
In the Northern Hemisphere, the Earth’s rotational axis points very close to the
star Polaris, the North Star. This can be easily be demonstrated by pointing at
Polaris with your index finger, and after several minutes the sky will have rotated
from its original position around your finger. When the RA axis is pointed at
Polaris, the telescope can follow the path of the stars as they rotate around their
rotational axis.
There are several methods of aligning the RA axis to the Earth’s rotational axis;
the quickest and easiest method is to align the RA axis to Polaris. This will keep
celestial objects centered in the telescope’s field of view over time with adjustments to the RA slow motion control cable. Swing the optical tube of the telescope
about the declination (DEC) axis so that the tube is parallel to the RA axis. The
DEC setting circle should read +90. Move the tripod so that the RA axis roughly
lines up with Polaris. Adjust the latitude (tilt) of the RA axis up and down until
Polaris is in the center of the field of the finder scope; center Polaris in the crosshairs. Then, with the 25mm eyepiece in the focuser,repeat the process of adjusting
the tilt of the RA axis so that Polaris is in the center of the field in the 25mm
eyepiece. Using the T-knob on the side of the mount, lock down your latitude
position . . . this should not have to be adjusted again unless it comes loose or you
go to an observing site several hours North or South of your main site.
Moving the telescope from object to object is accomplished by loosening the RA
and DEC axes locking mechanisms and moving the telescope into the general
area you wish to observe. Lock down the axes by tightening the knobs and locate
the object using the slow motion cables. Moving the tripod is not necessary. To
keep the object in the field of view of the telescope over a period of time, use the
RA slow motion control to keep the object centered. You are moving the RA axis
to follow the sidereal motion of the object around the rotational axis of the Earth.
Tube Balancing
Balancing the optical tube to the mount’s two axes of rotation is critical for the
equatorial mount to operate smoothly. If unbalanced, there will be torque put on
one axis of the mount, and the telescope will tend to shift at the most awkward
moment so the heavier end will be lower than the lighter end.
To balance your telescope, set the mount so the DEC setting circle reads +90.
Rotate the telescope in RA until the counterweight is on one side of the mount
and the tube on the other. Leave the RA lock knob loose so the telescope will
rotate freely in the RA axis. Adjust the counterweight so when horizontal, the
telescope does not rotate in RA, and then tighten the RA lock knob. You will
now want to release the DEC axis lock knob and slide the optical tube forwards
and back in the cradle rings until there is no torque in the DEC axis. Now the
telescope is completely balanced and will not move without being touched,
regardless of the axes being locked down.

bearing surface by scratching it up.
To carry the telescope out of the house for at-home viewing, you can easily carry
the tube and base separately. Use common sense when moving the telescope.
While the components are not terribly heavy, they are bulky; use caution to avoid
hurting yourself. If in doubt, get someone to help you.
Field Use and Set-Up
When selecting a location for observing, be sure to place the telescope as far away
as possible from direct artificial light, such as street lights, porch lights, and automobile headlights. The glare from these lights will seriously impair your night
vision. The telescope should be located on a relatively level surface for proper
operation of the mount. You may set it on a sturdy level platform to increase the
height of the eyepiece, but be sure it’s strong enough and does not wobble.
Tracking an Object
When viewing the night sky, celestial objects will drift out of the telescope’s field
of view due to the rotation of the Earth. Equatorial mounts, like the one that
comes standard with the SkyView, are designed to compensate for this problem.
When aligned correctly with the rotational axis of the Earth, the right assention
(RA) axis of the telescope will match the Earth’s rotation and the celestial objects
Polar Alignment

9mm provides 111x. Many other eyepieces are available for more detailed closeup viewing, and for even lower power, wider field viewing. Most amateur
astronomers will end up with a selection of three to six eyepieces, making it possible to choose the right magnification, brightness, and contrast for each object
and for different observing conditions.
Switch up to higher magnification eyepieces only after you’ve located a small
object. Most viewers use the lowest power eyepiece all the time! Keep in mind
that higher powers will always be fainter and less sharp (this is a fundamental
law of optics). Naturally, higher magnifications are desirable for viewing many
celestial objects; we simply want to emphasize to the beginner that the low magnification eyepiece is definitely the one to use when searching for an object and
for a lot of extended viewing.
Exotic, extra-heavy eyepieces may cause enough imbalance on the tube that you
will need to re-balance the telescope.
7. Astronomical Viewing
How to Find Interesting Celestial Objects
You need to use a star chart or atlas to help find objects so you won’t be disappointed at what you see. Except for the moon and bright planets, it’s pretty
time-consuming to hunt down impressive nebulas and star clusters by trial-anderror. You should have specific targets in mind before you begin looking through
the eyepiece.
Don’t spend a lot of money on a fancy, expensive star atlas until you have seen
all the brightest objects listed in a basic atlas. The Edmund Mag 6 Star Atlas is
highly recommended for all levels. A Planisphere will help you learn the constellations visible at a given time of night and any particular date. Use a
red-light flashlight to preserve your night-adapted vision.
You can locate Saturn, Jupiter, Venus, Mars, and the other planets by referring to
the charts published in Astronomy or Sky & Telescope magazines each month.
These objects are fun to follow across the skies as the months go by.
Unless you know exactly where to look, you'll need a star atlas to locate celestial
objects. Don’t expect to find anything interesting without one! The universe is
vast, and it will take a LONG time to find interesting subjects if you just scan
at random!
The Moon
Night viewing of the moon and its surface detail is one of the easiest and most
interesting ways to first use your telescope. The best time to observe is when the
moon is not full, as the shadows on the surface reveal more detail. You may want
to try using more powerful optional eyepieces for observing the details of the
moon’s surface.

6. Observing Tips & Techniques
Seeing Limitations
Atmospheric conditions vary significantly from night to night. If the stars are
twinkling noticeably, upper atmospheric turbulence may limit viewing to low
powers. Planetary observing may be very limited under these conditions as the
higher magnifications necessary to see detail will only give a blurry image in
the eyepiece.
Cooling Your Telescope
Allow at least one-half hour for your scope to cool. In very cold climates (below
freezing), it is essential to store the telescope as cold as possible. If the scope has
to adjust to more than a 40° temperature change, allow at least one hour for the
optics to adjust. All optical instruments need time to reach “thermal equili-brium.” The bigger the instrument and the larger the temperature change, the more
time is needed.
Atmospheric distortions (dust in the air, air currents, etc.) will show up at higher
magnifications. With an out-of-focus star image, any movement across the
“disc” will be a result of an unstable atmosphere. Make sure you are not looking
over buildings or any other source of heat; that will also cause the image to
become distorted.
If the movement is on one side of the disc, or there is a distinct slow-moving
bump or spike in one section, this is an indication of tube currents. To solve this
problem, let the telescope cool down longer, or store cold (outside garage or storage facility) to minimize the temperature change needed to reach equilibrium.
Do You Wear Eyeglasses?
Keep your glasses on to begin with. Just look though the eyepiece and adjust the
focus knob for the best image. Many people prefer to remove their glasses and
just re-focus the telescope (especially with higher power eyepieces).
Preserve Your Night Vision
Don’t expect to walk directly from a normally-lit house into a back yard, and
immediately see faint nebulas, galaxies, or star clusters. Your eyes take about 30
minutes to reach perhaps 80% of their full dark-adapted sensitivity. Many observers notice improvements after several hours of total darkness. Very bright
daylight for extended times can affect your night vision for days. So please,
give yourself at least a little while to get used to the dark. (Nearby porch and
street lights seriously affect night vision, as do automobile headlights. )
Eyepiece Selection
Always start up with your lowest-power, widest-field eyepiece. Of the telescope’s standard eyepieces, the 25mm Kellner provides 40x magnification, which
is moderately low and provides very bright images of deep space objects; the
power eyepieces, depending on the object, may be needed as well. Take plenty of
time to get used to the dark. Don’t expect these subjects to appear like photographs in magazines. As you become more experienced, you will see more and
more detail. (Our eyes are not sensitive enough to see color in deep sky objects
except for a few of the brightest ones. ) Use your star atlas to choose deep space
objects for the date and time you are observing.

Terrestrial Viewing
Your telescope is capable of focusing on distant terrestrial subjects; however, the
image will be reversed. With the addition of an optional image correcting prism,
your SkyView 90 can be used for all types of terrestrial viewing.

The Planets
Planets are the brightest objects after the sun and the moon. While the positions
of the stars remain fixed relative to each other, the positions of each planet are
constantly changing. Don’t be disappointed that you can’t tour all the visible
planets when your first get your telescope . . . you must limit yourself to planets
which happen to be well placed for observing at the moment.
Some daily newspapers, the magazines Sky & Telescope and Astronomy, or Abrams
Planetarium Sky Calendar will tell you the location of planets and the times they
are visible. Your SkyView 90 is capable of showing you the planets Venus, Mars,
Jupiter and Saturn in some detail. Other planets may be visible but will likely
appear star-like. Since planets are quite small, optional higher power eyepieces
are recommended and often needed for detailed observations.
JUPITER The largest planet, Jupiter, is a great subject for the SkyView 90. You can
see the disc of the giant planet, and watch the ever-changing positions of four of
its largest moons – Io, Callisto, Europa, and Ganymede. Higher-power eyepieces
should bring out the cloud bands and perhaps even the Great Red Spot (which
has faded to yellow in recent years).
SATURN The ringed planet is a breathtaking sight when Saturn is well positioned. The angle the rings present to the earth varies over a period of many
years . . . sometimes they are seen edge-on and are entirely invisible as they are
in 1995! Other times, they are broadside and easily seen as giant “ears” on each
side of Saturn’s disc. A steady night is necessary. You will probably see a bright
“star” close by, which is Saturn’s brightest moon, Titan.
VENUS At its brightest, Venus is the brightest object in the sky after the sun and
the moon. It will appear as a thin crescent when at its brightest. It is never seen
too far from the morning or evening horizon, being close to the sun. Sometimes
Venus is even visible to the naked eye during full daylight! No surface markings
can be seen as Venus is always covered with dense clouds.
MARS The Red Planet makes its closest approach to Earth every two years
(February 1995, March 1997, April 1999). During close approaches you’ll see a red
disc, and may be able to see the polar ice cap. To see surface detail on Mars, you
will need a high power eyepiece and a very steady night!
The Stars
Stars will appear like twinkling points of light. Even the more 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 double stars. The famous “DoubleDouble” in Lyra and the two-color double star Alberio in Cygnus are favorites.
Deep Sky Objects
Under dark skies, you can observe fascinating deep sky objects including
Nebulas, Star Clusters, Galaxies, and many more. Many of the objects will appear
as faint smudges or be invisible except under dark skies; higher power or lower
Your Orion SkyView 90 will provide years of viewing pleasure for you and
your family.

8. Care and Maintenance
Care of the Mount and Tube Assembly
Give your telescope reasonable care and it will last a lifetime. Store it indoors or
in a dry garage. Do not leave the telescope outside except when using it. Keep it
covered with a plastic tarp or drop cloth to keep dust and dirt off. The optical
tube is aluminum and has a smooth painted surface that should resist scratches
and smudges. If a scratch does appear on the tube, it will not harm the telescope.
If you wish, white auto touch up paint will cover the scratch nicely. Smudges can
be wiped off with standard household cleaners such as Windex or 409. The gears
on the equatorial mount should not need to have grease applied to them except
after a long period of storage or if you have been observing in a particularly
dusty site. Apply a thin ribbon of grease (automotive bearing grease works best)
just where the worm gear mates to the gear wheel, then work the grease around
the worm and wheel by rotating the slow motion control cables.
Care of the Optics
Any quality “Optical” lens cleaning tissue and “Optical” lens cleaning fluid specifically designed for multi-coated optics can be used to clean the exposed lenses
of your eyepieces or finder scope. Never use regular glass cleaner or cleaning
fluid designed for eyeglasses. Always put the fluid on the tissue, never on the
optics. Use lots of tissue on larger lenses. Never reuse tissue. Don’t take eyepieces apart for cleaning!
Always remove any dirt or grit with a light wipe with a moistened tissue, and
then re-clean with another tissue. Don’t grind dirt in! Oily fingerprints and
smudges may be removed using this method. Don’t smear dirt around; remove
it gently!
Cleaning the Objective Lens
The objective lens should not require cleaning unless it is touched and skin oils
are deposited upon the lens. Simply blowing off the dust with a blower bulb will
maintain the performance of your SkyView 90. If you need to clean the objective
lens, use the following procedure to ensure the lens will not be harmed.
Blow off the dust and dirt particles with a blower bulb; you can use a can of
compressed air provided you follow the directions very carefully. Canned air,
if held at an angle to the lens, has compounds that can get on the lens and are
very difficult to remove. Using a cleaning fluid that is safe for multi-coated
optics, put a drop or two onto a lens tissue that is also safe for multi-coated
lens (available at quality camera shops). Wipe the tissue across one-half of the
lens, and then, with a fresh tissue, dry off that half the lens. Repeat this process
using fresh tissues to clean the other half of the lens. Use a clean dry tissue to
touch up any areas as needed. The tissue may leave fibers on the lens; these
can be blown off with a blower bulb.
