INFINITY SERIES

80, 90, 102mm Telescopes

WARNING!

Never use a Meade® telescope to look at the Sun! Looking

at or near the Sun will cause instant and irreversible

damage to your eye. Eye damage is often painless, so

there is no warning to the observer that damage has

occurred until it is too late. Do not point the telescope at

or near the Sun. Do not look through the telescope or

viewfinder as it is moving. Children should always have

adult supervision while observing.

INTRODUCTION

Your telescope is an excellent beginner’s

instrument, and is designed to observe

objects in the sky and also on land. It can

be your personal window on the universe or

allows you to intimately study the behavior of

nesting birds on a distant hillside.

The telescope is shipped with the following

parts:

• Optical tube

• Alt-azimuth mount with slow motion con-

trols

• Stainless Steel tripod with accessory tray

• Three 1.25” eyepieces:

MA26mm, MA9mm, MA6.3mm

• 90 degree erect-image diagonal prism

• 2X Barlow

• Red-dot viewfinder with bracket

The Infinity series of telescopes come in sev-

eral sizes (apertures) of optical tubes. The

heart of the optical tubes is the front lens. It

collects and focuses the incoming light from

distant objects.

The lens diameter is one of the most

important pieces of information about the

telescope. The size of the objective lens

determines how much detail you will be able

to see in your telescope.

Each optical tube also has a focal length

which is the distance the light travels inside

the optical tube before it comes to focus.

The focal length information is also important

and will help later on to calculate magnifica-

tion.

Setting up your telescope involves these

simple steps:

• Setting up your tripod

• Attach the accessory tray

• Attach the slow motion controls

• Attach the optical tube to the mount

• Attach the viewfinder

• Attach the diagonal prism and eyepiece

• Align the viewfinder

Study the picture on the next page and

become acquainted with the parts of your

telescope. Then proceed to “Setting up your

tripod.”

SETTING UP YOUR TRIPOD

The tripod is the basic support for your tele-

scope and comes pre-assembled from the

factory; except for the accessory tray. The

tripod height may be adjusted so that you

can view comfortably.

Note: Number in brackets, e.g., (3), refer

to the item numbers in Fig. 1.

1. To setup the tripod, spread the legs out

evenly and place it on a solid surface.

2. Set the height of your tripod:

a. Rotate and loosen the leg lock thumb-

screw (18) to unlock the leg lock.

b. Slide the inner portion of the leg (17) in

or out to the desired length. Repeat for

the other two legs.

c. Rotate and tighten the leg lock thumb-

screw to re-lock the leg lock.

d. Repeat for the other two legs.

ATTACH THE ACCESSORY TRAY

The accessory tray attaches at the center of

the tripod legs and is a convenient place to

hold eyepieces and other Meade accessories

while observing, such as the Barlow lens.

To attach, place the hole in the center of the

accessory tray over the attachment point as

shown in Fig 2. Then rotate the tray until the

wings of the tray snap into place on the tripod

leg brace supports(9).

To remove the tray, rotate the tray so it

unlocks from the leg brace supports (9), then

remove.

ATTACH THE SLOW-MOTION CONTROLS

The slow motion control cables (11 & 12) allow

you to make fine adjustments to the pointing

position of the optical tube. When viewing

objects in the night sky, you will notice that

the object moves slowly in the eyepiece. This

is caused by the Earths rotation. Use the slow

motion controls to follow (or “track”) these

objects as you observe. Note that each

axis has its own slow motion control

which is independently controlled.

To install, attach the flexible cables

(11 & 12) to the mount as shown in Fig 3.

The cables are secured in place with a firm

tightening of the thumbscrews located at the

attachment ends of each cable.

3. Turn the optical tube attachment knob

(24) counter-clockwise until firm.

4. To remove the optical tube, first support

the optical tube in one hand. Next, turn

the attachment knob (24) clockwise until

the OTA detaches from the mount.

ATTACH THE VIEWFINDER

An eyepiece (1) has a narrow field of view.

The included viewfinder (2) has a wider field

of view and red dot to make it even easier

to locate the viewing object. The red dot

viewfinder also comes with an easy to install

dovetail bracket.

1. To install the red dot viewfinder, slide the

viewfinder bracket into the dovetail adapter

( ).Fig 5

2. Next, secure the viewfinder in place with

the single locking knob.

ATTACH THE DIAGONAL PRISM AND

EYEPIECE

The erect-image diagonal prism reflects the

light from the optical tube to a more com-

fortable viewing position. It also corrects the

image orientation so the image is right side

up, and correct left-to-right.

1. To install, slide the diagonal prism (13)

into the focuser draw tube (15).

2. Tighten the draw tube thumbscrew to hold

the diagonal prism securely (15).

3. Next, slide the MA 26mm eyepiece (1)

into diagonal prism.

4. Tighten the diagonal prism thumbscrew to

hold the eyepiece securely.

ALIGN THE VIEWFINDER

Perform the first part of this procedure during

the daytime and the last step at night.

1. Point the telescope at an easy-to-find land

object such as the top of a tele-

ATTACH THE OPTICAL TUBE TO THE

MOUNT

The optical tube gathers distant light

which is focused in the eyepiece. It

attaches to the mount using the optical tube

attaching knob (24) and dovetail mounting rail

(6).

1. To attach the optical tube, first locate the

threaded hole on the bottom side of the

dovetail mounting rail(6) ( ).Fig 4

2. Using the optical tube attaching knob

(24), place the dovetail onto the top of the

mount, lining up the threaded
