2. Understanding Celestial Motion and

Coordinates

Understanding where to locate celestial objects and

how these objects move through the sky is

fundamental to fully appreciating astronomy as a

hobby. Most amateur astronomers use the same

visual path (or star-hopping) method for locating

celestial objects. To do this they use maps of the

sky or an astronomy program that identifies bright

stars and constellations of stars that serve as

"roadmaps" and "markers" in the sky. These visual

reference points guide amateur astronomers in

their search for astronomic objects and although

the visual path method is the preferred

approach—giving thought to whether or not to use

circles of digital coordinates for locating objects is

desirable as your telescope offers this function. Be

warned however, when compared with a visual path

approach, looking for objects using circles of digital

coordinates requires a greater investment in terms

of patience and time in order to achieve a more

precise alignment of the telescope's polar axis on

the celestial pole. This is partially why the visual

path approach is preferred since it’s the simplest

(and quickest) way to get started.

Understanding how astronomic objects move

Given the earth's rotation, celestial bodies (stars)

appear to move from east to west along a curved

trajectory across the sky. The trajectory that they

follow is known as the right ascension line (R.A.).

The angle of the trajectory that they follow is known

as the declination line (Dec.). The right ascension

and the declination form a system that is similar to

the terrestrial system of latitude and longitude.

In the system of R.A. and Dec. coordinates, stars

are projected onto the "celestial sphere", i.e. onto

the imaginary sphere where all of the stars appear

to be located.

Understanding celestial coordinates

In the system of celestial coordinates, the poles are

defined as being the two points where the earth's

rotation axis, when prolonged infinitely to the north

and to the south, intersects with the celestial

sphere. Consequently, the celestial North Pole is

the point in the sky where the prolongation of the

earth's axis passing through the North Pole

intersects the celestial sphere. In fact this point in

the sky is located close to the North Star or pole

star (Polaris).

So-called "longitude lines" are drawn on the earth's

surface between the north and south poles. In the

same way, "latitude lines" are drawn along an

east-west direction, parallel to the earth's equator.

The celestial equator is simply a projection of the

earth's equator into the celestial sphere. Just like

on the earth's surface, imaginary lines have been

drawn on the celestial sphere to form a grid of

coordinates. The positions of the stars on the

earth's surface are specified by their latitude and

longitude.

The celestial

equivalent to terrestrial

latitude is called

"Declination" or simply

"Dec", expressed in

degrees, minutes, and

seconds north (“+”) or

south ("-") of the

celestial equator.

Consequently any

point located along the

celestial equator (e.g.

passing through the

constellations of Orion,

Virgo and Aquarius) is

specified by its

declination of 0º0’0”.

The declination of the

North Star or pole star located very close to the

North Celestial Pole is +89.2º.

The celestial equivalent to terrestrial longitude is

called "Right Ascension" or "R.A.", expressed in

hours, minutes and seconds from a "zero" R.A. line

defined arbitrarily and which passes through the

constellation of Pegasus. The coordinates of the

Right Ascension range from 0h 0mn 0s to 24h 0mn

0s (not inclusive). Therefore, there are 24 primary

(Polaris)) Star

R.A. lines located at 15 degree intervals along the

celestial equator. The objets that are further away,

eastwards, from the primary Right Ascension grid

line (0h 0mn 0s) carry rising R.A. coordinates.

Consequently, once it is possible to specify the

position of all of these celestial objects using their

Right Ascension and Declination coordinates the

task of searching for objects (especially low

brightness stars) using the astronomer's telescope

may be simplified. The digital, R.A. (16) and Dec.

(13) setting circles for your telescope can be made

up, in practice to read the object's coordinates, by

positioning it close to the telescope's telescopic

field of view (FOV). The advantage of using these

setting circles is however only justified after first

correctly aligning the telescope with the North

Celestial Pole.

3. Getting Started

Before you can use the telescope effectively, there

are still a few steps to be performed.

3.1. Selecting an Eyepiece

1. Always begin viewing with the lowest power

eyepiece. (Note: a 20 mm focal length eyepiece is

lower power than a 12.5 mm one.) A formula can

be used to determine the power of each eyepiece:

Telescope focal length divided by eyepiece focal

length equals magnification. Ex. 900mm ÷ 20mm =

45X (magnification)

2. Included with this telescope is a 90° Star

Diagonal.

3.2. Focusing Telescope

1. After selecting the desired eyepiece aim the

main telescope tube at a land-based target at least

200 yards away (e.g. A telephone pole or a

building). Fully extend focusing tube by turning the

focus knob.

2. While looking through selected eyepiece, slowly

retract focusing tube by turning focusing knob until

object comes into focus.

3.3. Aligning Finderscope:

The extended field of vision offered by the 5x24

mm finderscope (8) makes it easier to aim at an

object before viewing it through the main telescope

tube with a higher magnification.

1). Remove the front lens cover (33) from the

sunshade (29). Look through Main Telescope Tube

and establish a well-defined target (see focusing

telescope section). Tighten all lock knobs

(Declination, Latitude, Right Ascension, Horizontal

Axis) so that telescope’s aim is not disturbed.

2). Looking through the finderscope, alternate

tightening or loosing each finderscope Adjustment

Screw (9) until the crosshairs of the finderscope

are precisely centered on the same object already

centered in Main Telescope Tube’s field of view.

3). Now, objects located with the finderscope first

will be centered in FOV of the main telescope.

They can be focused by turning the finderscope’s

threaded eyepiece. The image in the finderscope

will be reversed.

3.4. Balancing the Telescope

To insure smooth movement of the telescope on

both axes of the equatorial mount, it is imperative

that the optical tube be properly balanced. We will

first balance the telescope with respect to the right

ascension (R.A.) axis and then in the declination

(Dec.) axis.

1. Keeping one hand on the telescope optical tube

(11), loosen the R.A. lock knob (14). Make sure the

Dec. lock knob (12) is locked. The telescope

should now be able to rotate freely about the R.A.

axis. Rotate it until the counterweight shaft (17) is

parallel to the ground (i.e., horizontal).

2. Now loosen the counterweight lock knob (20)

and slide the weight along the shaft until it exactly

counterbalances the telescope. That’s the point at

which the shaft remains horizontal even when you

let go of the telescope with both hands.

3. Retighten the counterweight lock knob. The

telescope is now balanced on the R.A. axis.

4. To balance the telescope on the Dec. axis, first

tighten the R.A. lock knob (14), with the

counterweight shaft (17) still in the horizontal

position.

5. With one hand on the telescope optical tube (11),

loosen the Dec. lock knob (12). The telescope

should now be able to move freely on the Dec. axis.

Loosen the ring clamps on the tube rings (10) a few

turns, until you can slide the telescope tube forward

and back inside the rings (this can be aided by

using a slight twisting motion on the optical tube

while you push or pull on it).

6. Position the telescope in the tube rings (10) so it

remains horizontal when you carefully let go with

both hands. This is the balance point for the optical

tube (11) with respect to the Dec. axis.

7. Retighten the ring clamps.

3.5. Polar Alignment of the Equatorial mount

Objects located in the sky appear to revolve around

the celestial pole. In northern latitudes, the North

Star (Polaris) is close to the pole. (In actual fact,

stars are essentially "fixed" in place and their

apparent motion is caused by the earth rotating

around its own axis.) Over a 24 hour period, stars

will perform a complete revolution around the pole,

generating concentric circles with the pole at their

center. By aligning the telescope's polar axis with

the celestial north pole (or with the celestial south

pole for observers located in the earth's southern

hemisphere), astronomic objects may be followed

(or tracked) by simply moving the telescope around

an axis, the polar axis.

If the telescope is reasonably aligned with the pole,

changing the instrument's declination using its

flexible control cable will consequently be of little

use – almost all the telescope motion required will

take place using the Right Ascension coordinates.

(If the telescope is perfectly aligned with the

pole—no declination change will be required to

follow stellar objects). For occasional visual

observations through the telescope, aligning the

telescope's polar axis by one or two degrees in

relation to the pole is more than enough. With this

level of aiming precision the telescope can achieve

precise tracking if the R.A. flexible control cable is

used while maintaining the objects within the

telescope's FOV for some 20 to 30 minutes.

To polar-align the telescope:

1. Level the equatorial mount by adjusting the

length of the three tripod legs (2).

2. Loosen the latitude adjustment knob (24) and tilt

the mount until the pointer on the latitude scale is

set at the latitude of your observing site. If you don’t

know your latitude, consult a geographical atlas or

search the internet. For example, if your latitude is

35° north, set the pointer to 35. Then retighten the

latitude knob. The latitude setting should not have

to be adjusted again unless you move to a different

viewing location some distance away.

3. Loosen the Dec. lock knob (12) and rotate the

telescope optical tube (11) until it is parallel with the

R.A. axis, as it is in Figure 1. The pointer on the

Dec. setting circle (13) should read 90°. Retighten

the Dec. lock knob.

4. Loosen the azimuth adjustment knob (23) on the

mount and rotate the mount so the telescope tube

(and R.A. axis) points roughly at Polaris. If you

cannot see Polaris directly from your observing site,

consult a compass and rotate the mount so the

telescope points north. Retighten the azimuth

adjustment knob.

Figure 3: Finding Polaris

The equatorial mount is now polar aligned.

From this point on in your observing session, you

should not make any further adjustments in the

azimuth or the latitude of the mount, nor should you

move the tripod. Doing so will undo the polar

alignment. The telescope should be moved only

about its R.A. and Dec. axes.

4. Using the Telescope

With the telescope aligned on the pole, you are

now ready to start your observations.

4.1. Getting familiar with you mount and

telescope

Before observing a celestial object, looking at

terrestrial objects during the day provides a good

exercise on how to operate the mount and

telescope.

4.2. Star observation

First of all you will need to choose an object that is

easy to find. The Moon or a bright star is a good

target to start with.

1. Slightly loose the telescope's Right Ascension

locking knob (14) and the Declination locking knob

(12), located close to the Declination adjustment

ring (13). By applying slight pressure by hand, the

telescope should now move freely along its two

axes.

2. Move the telescope along R.A. and Dec axes

and using the aligned finderscope to find the Moon.

With the object centered in the finderscope's cross

hairs, retighten the R.A. and Dec. knobs.

3. The Moon should be visible somewhere within

the FOV of main telescope. Focus the image by

adjusting the focusing knob (26). Center the Moon

by adjusting the mount using RA and DEC control

cable (27, 28).

4. You’ll find that the object immediately starts to

shift across the FOV. This motion is due to the

earth rotation. To "track" the object and keep it in

the FOV, turn the cable that controls R.A. slow

motion (27). Objects will appear to move faster at

higher magnifications. The Declination control

cable (28) is only used for centering the object and

not for tracking.

4.3. Observation Tips

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 greatly

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

grass or dirt surface, not asphalt, because asphalt

radiates more heat, which 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. 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.

Furthermore, it is preferable to let your telescope

reach outside ambient (surrounding) temperature

before starting an observation cycle.

Wait a few minutes to allow your eyes to become

used to the darkness before attempting any serious

observations. Use a flashlight with a red filter to

preserve your night vision when looking at star

maps or checking telescope parts.

Avoid touching the eyepiece during observation.

Vibration generated by this contact may cause the

view to move. Also avoid observing from locations

where terrestrial vibrations are significant.

Observing from the upper floors of buildings may

also cause the images vibrating.

Warning! Never attempt to observe the sun

through your telescope without a proper solar filter.

Observing the sun, even for a fraction of a second,

may cause immediate and irreversible harm to your

eye as well as physical damage to the telescope.

Some atmospheres may deform the image that you

are observing. Planets in particular, when observed

low on the horizon, often present a fuzziness – the

same object when observed at a higher altitude in

the sky may benefit from far better definition and a

far higher degree of contrast. Furthermore, air

turbulence in the upper layers of the atmosphere

may cause "trembling" to affect the view observed

through the eyepiece. In this case, reduce the

magnification factor until the picture stabilizes.

Keep in mind that even a small sized but bright and

well defined image will reveal far more interesting

details than a larger, but less bright and slightly

fuzzy, view.

4.4. How to use setting circles

Understanding the Setting Circles

The setting circles on an equatorial mount enable

you to locate celestial objects by their “celestial

coordinates”. The R.A. and Dec. values for

celestial objects can be found in any star atlas or

star catalog.

The mount’s R.A. setting circle (16) is scaled in

hours, from 1 through 24, with small marks in

between representing 6-minute increments. The

numbers closest to the R.A. axis gear apply to

viewing in the Southern Hemisphere, while the

numbers above them apply to viewing in the

Northern Hemisphere.

The Dec. setting circle (13) is scaled in degrees,

with each mark representing 2° increments. Values

of Dec. coordinates range from +90° to -90°. The 0°

mark indicates the celestial equator. When the

telescope is pointed north of the celestial equator,

values of the Dec. setting circle are positive, while

when the telescope is pointed south of the celestial

equator, values of the Dec. setting circle are

negative.

Before you can use the setting circles to locate

objects, the mount must be correctly polar aligned,

and the R.A. setting circle must be calibrated. The

Dec. setting circle has been permanently calibrated

at the factory, and should read 90° whenever the

telescope optical tube is parallel with the R.A. axis.

Calibrating the Right Ascension Setting Circle

1. Identify a bright star in the sky near the celestial

equator (Dec. = 0°) and look up its coordinates in a

star atlas.

2. Loosen the R.A. and Dec. lock knobs (14, 12) on

the equatorial mount, so the telescope optical tube

can move freely.

3. Point the telescope at the bright star whose

coordinates you know. Lock the R.A. and Dec. lock

knobs. Center the star in the telescope’s field of

view with the R.A. and Dec control cables.

4. Rotate the setting circle until the metal arrow

indicates the R.A. coordinate listed in the star atlas

for the object

Finding Objects With the Setting Circles

Now that both setting circles are calibrated, look up

in a star atlas the coordinates of an object you wish

to view. Loosen the Dec. lock knob (12) and rotate

the telescope until the Dec. value from the star

atlas matches the reading on the Dec. setting circle

(13). Remember that values of the Dec. setting

circle are positive when the telescope is pointing

north of the celestial equator (Dec. = 0°), and

negative when the telescope is pointing south of

the celestial equator. Retighten the lock knob.

Loosen the R.A. lock knob (14) and rotate the

telescope until the R.A. value from the star atlas

matches the reading on the R.A. setting circle (16).

Remember to use the upper set of numbers on the

R.A. setting circle. Retighten the lock knob.

Most setting circles are not accurate enough to put

an object dead-center in the telescope’s eyepiece,

but they should place the object somewhere within

the field of view of the finderscope, assuming the

equatorial mount is accurately polar aligned. Use

the R.A. and Dec control cables to center the object

in the finderscope, and it should appear in the

telescope’s field of view.

The R.A. setting circle must be re-calibrated every

time you wish to locate a new object. Do so by

calibrating the setting circle for the centered object

before moving on to the next one.

4.5. Calculating the Power

The power or magnification offered by a telescope

is determined by two factors: the optical or focal

length of the telescope's lens and the eyepiece's

focal length. This telescope's focal length is 900

mm. To calculate the magnification factor, divide

the lens' focal length by that of the eyepiece. The

resulting value represents the magnification factor

offered by the telescope when it is used with this

eyepiece. For example, using a 20 mm eyepiece

provides a magnification factor of:

Magnification = 900 mm/20 mm = 45X

Dec. setting circle

R.A. setting circle

Dec. mark

R.A. mark

A Barlow lens is used to increase the magnification

of each eyepiece. First insert the Barlow 3X lens in

the telescope’s eyepiece holder, then the diagonal

mirror and the eyepiece itself. Secure the lens

using thumbnail screws. The total magnification will

be 135X when a 20 mm eyepiece (45X) and a 3X

Barlow lens are used together.

Some words of caution on magnification.

Although the theoretical power or magnification of

a telescope is virtually limitless, there are practical

limits, such as he earth's atmosphere. Every

telescope has a useful magnification limit of about

2X per millimeter of aperture. This comes to 140X

for the 900X70. Moderate magnifications are what

give the best views. It is better to view a small, but

bright and detailed image than a dim, unclear,

oversized image.

5. 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 caps on the front of the telescope and on

the focuser drawtube when not in use.

Your 900X70 telescope requires very little

mechanical maintenance. The optical tube is

aluminum and has a smooth painted finish that is

fairly scratch resistant. If a scratch does appear, it

will not harm the telescope.

Cleaning Lenses

Any quality optical lens cleaning tissue and optical

lens cleaning fluid specifically designed for

multi-coated optics can be used to clean the

objective lens and the exposed lenses of your

eyepieces. Never use regular glass cleaner or

cleaning fluid designed for eyeglasses.

Before cleaning with fluid and tissue, blow any

loose particles off the lens with a blower bulb or

compressed air. 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.

For the larger surface of the objective lens, clean

only a small area at a time, using a fresh lens tissue

on each area. Never reuse tissues.

This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

iOptron reserves the right to modify or discontinue, without prior notice to you, any model or style telescope.

If warranty problems arise, or if you need assistance in using your telescope, mount, or controller contact:
