INSTRUCTION MANUAL

WARNING: Never look directly at the Sun through your telescope or its finder scope — even for

an instant — as permanent eye damage could result. Do not point the telescope at the Sun, as

parts will melt! Children should use this telescope only with adult supervision.

The Western Montana Astronomical Association

The WMAA is an educational organization that promotes public awareness of astronomy.

We hold public star parties, demonstrations, presentations, and discussions, all free of

charge.

Visit http://missoulasky.org for more information about club events and contact

information.Our meetings are typically the 2nd Friday of every month either at the Target

Range School Library or the Montana Natural History Center’s Native Garden Plant

Classroom. See the website for details about upcoming meetings.

The checkout program and telescope are modeled after a similar one in New Hampshire.

The WMAA partially funded this telescope and is providing the library with ongoing help

in public education about astronomy and maintenance of this telescope.

We hope you enjoy using it!

Transporting the Telescope

The telescope comes in a hard carrying case to minimize damage while transporting the telescope

and bundle accompanying items along with it. It is easy to lift with one person, though two can be

helpful to navigate it through doors and into cars. Grab both handles securely and ensure that the

clasps on the front of the case are closed completely before lifting. The picture below illustrates

how the telescope should be fitted

into the case. Please flip the

telescope tube over on the mount so

that the eyepiece is pointing

downward into the case (don’t bind

up the strings that attach the caps to

the mount). Put the telescope into

the case as shown, close the lid

gently, and turn the clasps

clockwise to lock the lid shut. The

case should fit easily into the back

seat of a car or the trunk.

Care and Maintenance

Aligning the Mirrors: Again, please don’t. If it seems that the telescope is in need of adjustment,

please tell a librarian.

Fog on the mirrors and eyepieces: One of the odd things that happens when star gazing is that

dew forms on pretty much everything (and everyone). The big mirror is tucked safely down at the

bottom of the telescope, and so it does not get much dew on it. Eyepieces, however, often have dew

form on them, making them useless until they warm up and dry out. If the eyepiece fogs up, wrap

your hands around it for a few moments. As it warms up, the fog should disappear. Please don’t

wipe the lens with a tissue or cloth as it has special coatings on it that could be damaged if you do.

Please ask people to not touch the lens… ever.

The Eyepiece chart on the telescope shows what magnification you will have for each setting of the

Zoom Eye piece. The “True Field” describes the width of the image in the eyepiece. A full Moon is

30 minutes of a degree (or !of a degree) wide, so you could fit about 4 full Moons in the field of

view when using the 8mm setting. Change the zoom setting until your target fits the eyepiece the

way you like. You will have to tweak the focus.

Getting Started

Please read the instructions and practice with the telescope inside before you take it out in the dark.

The image will be much better if you let the telescope cool down to air temperature before you start

observing.

This is a “Push-to” telescope. Once you find what you are looking for, you can either watch the

object move through your “field of view” (what you see through the eye piece) and then reposition

the telescope, or keep pushing the scope to hold the object in the center of the eyepiece. Objects

appear to move across the field of view faster at higher magnifications. This is because the field of

view becomes narrower.

Like many reflector telescopes, the image in the eyepiece is upside-down. When looking at star

charts you will have to keep this in mind. The Moon map on this telescope is “flipped” so it

matches what you see in the eyepiece.

Do You Wear Eyeglasses? If so, you will probably be able to observe with your glasses off by just

refocusing the telescope to your unaided vision. If your eyes are astigmatic, images will probably

appear best with glasses on. This is because a telescope’s focuser can accommodate for

nearsightedness or farsightedness, but not astigmatism.

This is important enough to say again:

WARNING: Never look directly at the Sun through your telescope or its finder scope — even for an

instant - as permanent eye damage could result. This is one of the few really bad things you can do

to yourself twice. Young children should use this telescope only with adult supervision.

Focusing the Telescope: Try out the telescope during the day when you can see what you’re doing.

Remove the dust caps from the eyepiece and telescope tube.

The “power” of a given telescope depends upon the eyepiece you use. This scope has a zoom

eyepiece. Always start by using the telescopes’ lowest-power (turn the body of the zoom so the

pointer is at “24”) to locate and center an object. Low magnification shows a larger area of sky in

the eyepiece, making finding and centering an object much easier.

With the eyepiece adjusted for low power (24 mm), aim the telescope in the general direction of an

object at least 1/4-mile away. Slowly rotate the focus wheels until the object comes into sharp

focus. Go a little bit beyond sharp focus until the image starts to blur again, then reverse the

rotation of the knob, just to make sure you’ve hit the exact focus point. When focusing on stars,

bring them to as small a point as possible.

Many “deep-sky” objects are big, but dim. Low magnification will be better for them. Once you’ve

centered an object in the eyepiece, you can switch to a higher magnification by twisting the zooms’

barrel towards the “8”. This is recommended for small and bright objects, like planets and double

stars. The Moon also takes higher magnifications well. You may have to refocus a little after

changing power.

If you find that it’s awkward to put your eye up to the eyepiece, you can rotate the telescope tube

by loosening the knob on the tube clamp and moving the telescope tube until the focuser is in a

convenient position. Be sure to tighten it again!

You may find that the telescope tube is either too hard to move or does not stay in place. Use the

altitude adjustment tension knob (it holds the telescope to the upright part of the base) to find the

right level of tension.

Operating the EZ Finder

A “finder scope” helps you point the scope, rather like a rifle sight. The EZ Finder works by

projecting a tiny red dot onto a screen mounted in the front of the unit, so that when you look

through the screen, the red dot will appear to float in space. Turn the power knob clockwise until

you hear a “click” indicating that power is on. With your eye positioned near the rear of the

telescope, look through the EZ Finder with both eyes open to see the red dot. The intensity of the

dot can be adjusted by turning the power knob. Use the dimmest possible setting that allows you to

see the dot without difficulty. When the EZ Finder is properly aligned with the telescope, an object

that is centered on the EZ Finder’s red dot should also appear in the center of the telescope’s

eyepiece. Checking the alignment of the EZ Finder is easiest during daylight. Aim the telescope at a

distant object, such as the top of a telephone pole or chimney and center it in the telescope’s

eyepiece. Now, turn the EZ Finder on and look through it. The object should appear near or under

the red dot. If not: Without moving the telescope, use the EZ Finder’s left/right (azimuth) and up/

down (altitude) adjustment knobs to position the red dot on the object in the eyepiece. If the red dot

is centered on the object in the eyepiece, you’re done!

The finder scope has a battery pack attached to the telescope. At the end of your observing session,

be sure to turn the power knob counterclockwise until it clicks off.

What to Expect

Depending upon what is in the sky; Planets will look small, but you might be able to see cloud

bands on Jupiter or the rings of Saturn. Craters on the Moon will be clear and numerous, the

waxing and waning of Venus should be visible, and many bright deep-sky objects will fill the

eyepiece. Don’t expect to see color as you do in NASA photos as our eyes are not sensitive enough
