INTRODUCTION  
Before you begin, we urge you to take a few minutes to completely read this manual so that you can  
get the best use of the equipment. This manual details the set-up, operation, specifications and  
optional accessories of the Polaris 60-AZ-D altazimuth refracting telescope. Designed for both  
astronomical and terrestrial observing, the Polaris 60-AZ-D will be your companion in exploring a  
universe of celestial and earthly objects.  
STANDARD EQUIPMENT (Refer to Fig. 1)  
Complete optical tube assembly (objective lens diameter = 60mm; focal length = 700mm)  
Full-length, fully adjustable, aluminum tripod and accessory tray.  
H 25mm (28X), H 12.5mm (56X), and SR 4mm (175X) Eyepieces (0.965" O.D. “Outside Diameter”)  
3x Barlow Lens (0.965" O.D.)  
Diagonal mirror (0.965" O.D.)  
5 x 24mm viewfinder with bracket  
Altazimuth mount with micro-altitude control  
Hardware package: A. 3 bolts (3" long) with wing nuts and washers  
B. 3 screws (1/2" long) with wing nuts and screwdriver tool  
Note: All other necessary hardware provided in place.  
StarLocator astronomy software (separate instructions supplied in software package)  
UNPACKING AND ASSEMBLY  
First time assembly of the telescope should require a set up of about 15 minutes. To set up the  
telescope, follow this procedure:  
1. Remove and identify the telescope’s components, using the listing above.  
2. Attach the 3 aluminum tripod legs (7, Fig. 1) to the base of the altazimuth mount (10, Fig. 1) with  
the 3 hinged leg brace supports (8, Fig. 1) facing inward. Three bolts (11, Fig. 1), each about 2"  
long, with washers and wing nuts, are provided for this purpose in hardware package “A.” Stand  
the telescope upright, spreading the tripod legs evenly apart so that the accessory tray can be  
positioned to attach to the 3 leg braces.  
3. Attach the accessory tray (9, Fig. 1) to the leg brace supports (8, Fig. 1) by threading the bolt on  
the bottom of the tray into the center hole located where the three brace supports meet (see Fig.  
1, Inset A) and turning the tray clockwise. Tighten to a firm feel, but do not overtighten—you will  
need to remove the tray if you wish to collapse the tripod. To remove the tray, just rotate the tray  
counterclockwise untill the tray comes loose.  
4. Extend the sliding center portion of the adjustable height tripod leg (19, Fig. 1) to the desired length  
for all 3 legs. Lock the tripod legs by tightening the leg lock thumbscrew (20, Fig. 1) to a firm feel.  
5. Remove the two vertical lock knobs (D, Fig. 2) from the optical  
D
C
tube assembly.  
6. Place the optical tube between the forks of the azimuth mount (A,  
Fig. 2), oriented as shown in Fig. 2.  
7. Slide the altitude rod (B, Fig. 2) into the hole in the altitude coarse  
adjustment control assembly (C, Fig. 2). Tighten to a firm feel.  
8. Thread a vertical lock knob (D, Fig. 2) through each of the holes in  
B
A
the forks of the azimuth mount (A, Fig. 2) and tighten to a firm feel.  
9. Attach the viewfinder bracket (2, Fig. 1) to the telescope using the Fig. 2 Mounting the optical  
tube assembly: (A) azimuth  
mount; (B) altitude rod;  
(C) altitude coarse adjustment  
control; (D) vertical lock knob.  
2 thumbscrews provided (25, Fig. 1). The thumbscrews fit through  
the 2 holes located at the base of the viewfinder bracket and  
thread into the main tube (see Fig. 1, Inset B).  
– 5 –  
 
10. Insert the diagonal mirror (13, Fig. 1) into the focuser drawtube (15, Fig. 1) and the H 25mm  
eyepiece (1, Fig. 1) into the diagonal mirror. Tighten the respective thumbscrews to a firm feel.  
11. The telescope is now completely assembled. To move the telescope and point it from one object  
to another, first slightly loosen one of the chrome-lock (star-shaped) knobs (5, Fig. 1) which serve  
as a vertical lock, then loosen the azimuth (horizontal) lock (6, Fig. 1). Also, slightly loosen the  
altitude coarse adjustment lock knob (17, Fig. 1). Loosening these locks allows the telescope to  
be moved freely (vertically or horizontally) in any direction so that the telescope can be positioned  
to center a terrestrial or celestial object in the telescopic field. Once an object is found, the altitude  
lock knob (17, Fig. 1) can be tightened and the altitude slow-motion fine-adjustment control knob  
(16, Fig. 1) can then be used to make very smooth and accurate tracking in the vertical axis.  
VIEWFINDER FOCUSING AND ALIGNMENT  
The 5 x 24mm viewfinder (2, Fig. 1) is a low-power, wide-field sighting device that, once aligned, will  
allow you to point the telescope with greater precision. Note: When you look through the viewfinder,  
you will see a crosshair with images that will be upside-down; this is normal.  
To work properly, the viewfinder must first be aligned to the telescope’s main optical tube. To align the  
viewfinder, follow these steps:  
1. Remove the lens cap (22, Fig. 1) of the optical tube assembly. Insert the 25mm wide-field eyepiece  
into the diagonal mirror (13, Fig. 1). Point the optical tube assembly (4, Fig. 1) at a distant land  
object (e.g. a distant telephone pole). Make sure the detail of the distant object you have chosen  
is in sharp focus. Focusing is accomplished by turning the focusing knob (23, Fig. 1) until the  
sharpest possible image is attained.  
2. Center the viewfinder (2, Fig. 1) in both the front and rear rings using the collimation screws (3,  
Fig. 1). Next, looking through the viewfinder, adjust the collimation screws on the rear ring until  
the object centered in the telescope’s main tube is likewise positioned in the center of the  
viewfinder’s crosshairs. Now it is possible to quickly sight an object in the viewfinder first, then find  
that object approximately centered in the 25mm eyepiece of the telescope.  
3. If the viewfinder’s infinity image is not in sharp focus, the knurled end of the eyepiece can be turned  
to fine tune the focus. Be sure to hold the viewfinder firmly between your fingers when making this  
adjustment.  
USING THE TELESCOPE  
With the telescope assembled, you are ready to begin observations.  
1. First, pick out an easy-to-find object. Observing land objects during the daytime is a good way to  
become accustomed to the operation of the telescope. At night, try observing the Moon at first (if  
it is visible) or a bright star.  
NEVER POINT THE TELESCOPE DIRECTLY AT OR NEAR THE SUN AT ANY TIME!  
OBSERVING THE SUN, EVEN FOR THE SMALLEST FRACTION OF A SECOND,  
WILL RESULT IN INSTANT AND IRREVERSIBLE EYE DAMAGE, AS WELL AS  
PHYSICAL DAMAGE TO THE TELESCOPE ITSELF.  
2. To center an object in the main telescope, first use the aligned viewfinder to find the object you  
wish to observe. If necessary, slightly loosen the vertical lock (5, Fig. 1) and the altitude rod lock  
knob (17, Fig. 1) to re-position the telescope so that the desired object can be centered in the  
viewfinder. When the object is centered in the viewfinder, it should then, also, be somewhere in  
the main telescope’s field of view. Next, using the 25mm eyepiece, center the object in the main  
telescope’s field of view, and sharply focus the image by turning the focus knob (23, Fig. 1).  
The wide-field H 25mm eyepiece included as standard equipment is the best eyepiece to use for  
the initial finding and centering of an object. The low-power H 25mm eyepiece presents a bright,  
wide field of view, ideal for terrestrial and general astronomical observing of star fields, clusters of  
stars, nebulae, and galaxies. For lunar and planetary viewing, switch to a higher power eyepiece  
such as the H 12.5mm — if you have good viewing conditions. If the image starts to become fuzzy  
– 6 –  
 
as magnification is increased, back down to a lower power; The atmosphere is not steady enough  
to support higher powers. Note: Changing eyepieces changes power.  
3. If you are observing an astronomical object (the Moon, a planet, star, etc.) you will notice that the  
object will begin to move slowly through the telescopic field of view. This movement is caused by  
the rotation of the Earth and makes an object appear to be moving in the telescope’s field of view.  
To keep astronomical objects centered in the field, simply move the telescope on one or both of its  
axes (vertical and/or horizontal) as appropriate. At higher powers, astronomical objects will seem  
to move through the field of view of the eyepiece more rapidly.  
Observing Tip: Place the object to be viewed at the edge of the field and, without touching the  
telescope, watch it drift through the field to the other side before repositioning the telescope so that  
the object to be viewed is again placed at the edge of the field, ready to be further observed.  
4. Avoid touching the eyepiece while observing through the telescope. Vibrations resulting from such  
contact will cause the image to move. Avoid observing sites where vibrations may introduce image  
movement. Viewing from the upper floors of a building may also introduce image movement.  
5. Allow a few minutes for your eyes to become “dark adapted” prior to attempting any serious  
observations. Use a red-filtered flashlight to protect your night vision when reading star maps, or  
inspecting components of the telescope. Tip: You can make your own red filtered flashlight by  
taping red cellophane over a flashlight lens.  
6. Avoid setting up the telescope inside a room and observing through an opened or closed window  
pane. Images may appear blurred or distorted due to temperature differences between inside and  
outside air. Also, it is a good idea to allow your telescope to reach the ambient (surrounding)  
outside temperature before starting an observing session.  
7. Planets and other objects viewed low on the horizon often lack sharpness — the same object,  
when observed higher in the sky, will appear sharper and have greater contrast. Turbulent air in  
the atmosphere can cause images to “shimmer” in the eyepiece. Try reducing power (change your  
eyepiece) until the image steadies. Keep in mind that a bright, clear, but smaller image is more  
interesting than a larger, dimmer, fuzzy one.  
8. Astronomical software or a good star atlas will assist you in locating many interesting celestial  
objects. These objects include:  
The Moon, covered with craters, mountain ranges, and fault lines. The Moon is best observed  
during its crescent or half phase when Sunlight strikes the Moon’s surface at an angle. It casts  
shadows and adds a sense of depth to the view. No shadows are seen during a full Moon,  
causing the bright Moon to appear flat and uninteresting.  
Cloud belts across the surface of the planet Jupiter.  
The 4 major moons of Jupiter, visible around the planet, changing position each night.  
Saturn and its famous ring system.  
Deep-Space: Nebulae, galaxies, multiple star systems, star clusters — hundreds of such  
objects are visible through your Polaris telescope. If possible, observe under a dark sky, away  
from city lights—you will be able to observe more deep-space objects through your Polaris  
telescope.  
Terrestrial objects: Your Polaris telescope may also be used for high-resolution land viewing.  
Important Note: Using the diagonal mirror results in an image which is reversed left-for-right,  
but which is correctly oriented up-and-down.  
Terrestrial observations should almost always be made using the 25mm low-power eyepiece  
for bright, sharp images. Observing horizontally through the Earth's atmosphere distorts  
images in higher-power eyepieces (such as 12.5mm).  
CALCULATING POWER  
The power (magnification) at which a telescope is operating is calculated by dividing the focal length  
of the telescope by the focal length of the eyepiece. The focal length of the 60-AZ-D telescope is  
identified on the focuser label as being 700mm (F = 700mm). The focal length of the eyepiece is  
usually identified on the top of the eyepiece barrel.  
– 7 –  
 
For example, if you are using a 25mm eyepiece, the resulting power will be:  
Power = 700mm ÷ 25mm = 28X.  
For example, if you are using a 12.5mm eyepiece, the resulting power will be:  
Power = 700mm ÷ 12.5mm = 56X.  
The purpose of a Barlow lens is to increase the magnification possible with a given eyepiece. The 3x  
Barlow supplied with this telescope will triple the normal eyepiece power. For example, the 25mm  
(28X) eyepiece, when used in conjunction with the 3x Barlow lens, yields 84X. The 12.5mm (56X)  
eyepiece yields 168X when used with the 3x Barlow lens.  
To use the 3x Barlow lens, remove the diagonal mirror (13, Fig. 1) from the focuser drawtube (15, Fig.  
1). Then insert the 3x Barlow lens, followed by the diagonal mirror (13, Fig. 1) and finally the 25mm  
eyepiece (1, Fig. 1). Refocus until the image is sharp.  
POWER AND EYEPIECES  
The useful higher magnification with any 60mm diameter telescope is in the range of 80 to 120 power.  
The general rule to follow with any telescope, regarding power: Only use as much magnification as a  
steady, well-defined image supports. The stability of the air varies and is one reason why having  
various eyepieces is desirable. Higher powers are no guaranty of better images; in fact, the opposite  
is often true.  
MAINTENANCE  
As with any quality optical instrument, lens surfaces should be cleaned as infrequently as possible. A  
little dust on the surface of the objective lens (14, Fig. 1) causes negligible degradation of image quality  
and should not be considered reason to clean the lens. When lens cleaning does become necessary,  
use a camel hair brush or compressed air to gently remove dust. Wipe only with a soft, clean cloth,  
applying as little pressure as possible to avoid scratching glass surfaces. Note: Gently pull off and  
remove the the dew shield/lens shade (21, Fig. 1) to access the objective lens (14, Fig. 1).

OPTIONAL ACCESSORIES  
#927 45° Erect-Image Roof Prism (0.965 O.D.): Correctly orients the telescopic image during  
terrestrial observing and yields an image position at a 45° angle to the main telescope tube, resulting  
in a more comfortable observing position in most cases.  
Additional Eyepieces (0.965"): Meade recommends the following eyepieces for enhanced  
astronomical and/or terrestrial viewing:  
MA 9mm (0.965" O.D.): Provides high quality, higher power, close-up observation of the Moon  
and planets (78X).  
MA 40mm (0.965" O.D.): Offers the most dramatic, wide field of view for observing deep-space  
objects. This is also the eyepiece most recommended for viewing objects on land (18X).
