Thank you for purchasing a Stellarvue

Telescope. Back in the mid 1960’s my
father bought me a 60mm refractor to
encourage my interest in science. That
telescope almost ended my interest in
astronomy altogether! With its wobbly
mount, inferior eyepieces and optics, I
struggled for several nights, then retired

the telescope to the closet. There are millions of cheap department store tele-
scopes sitting in closets. This should not be the case with your telescope. You
are now the owner of a quality telescope that is easy to use. Please look over
this manual to learn how easy it is use your new Stellarvue

WARNING!

LOOKING AT THE SUN CAN CAUSE SERIOUS EYE INJURY AND BLIND-
NESS. NEVER POINT A TELESCOPE OR BINOCULARS AT OR NEAR THE
SUN. VIEWING THE SUN WITHOUT A PROPER SOLAR FILTER MAY
RESULT IN BLINDNESS, AS WELL AS DAMAGE TO THE INSTRUMENT.
NEVER ALLOW CHILDREN TO USE BINOCULARS OR TELESCOPES DUR-
ING THE DAYLIGHT HOURS, UNLESS THEY ARE SUPERVISED BY AN
ADULT WHO UNDERSTANDS THE DANGER OF POINTING ANY OPTICAL
INSTRUMENT IN THE GENERAL DIRECTION OF THE SUN.

INTRODUCTION

Stellarvue telescopes are individually made and are
triplet tested before they leave the factory. Please store
and use it as you would any optical device. If dust accu-
mulates on the lens, you may use a bulb type blower to
remove it. Always be careful to avoid marring the lens.
Stellarvue refractors use a full multi-coating to increase
light transmission and contrast. Lenses are accurately
hand figured but may show some cosmetic marks which
do not affect performance. The telescope is internally

baffled and treated with an ultra flat black interior. The apo lens, dark interior
and full multi-coatings result in exceptional contrast and clarity.

Assembling your telescope is easy. Once it is assembled and adjusted, you
are ready to observe. The telescope may be easily moved. When transporting
with the focuser removed, use the dust cover to keep dust out of the tube
interior. We recommend storing the tube assembly in a padded, breathable
case to protect the finish. Do not leave it outside after observing with it. When
working in the field, it is a good idea to cover the telescope when not in use,
to prevent dust from settling on the optical and mechanical parts.

CARE AND MAINTENANCE

Keep the telescope covered when not in use with the lens caps in place. Cover the lens
to reduce the dust and debris that can fall onto the lens. When observing, extend the
dews hield all the way out to minimize the amount of dew that forms on the lens. If the
lens gets wet, bring it indoors and let it air dry before replacing the lens cap. Do not
store the telescope in an air tight container. Store it in a cool, dry place. Lens cleaning
should be done very infrequently. A small amount of dust or small spots on a lens will
not affect performance. If dust accumulates on the lens, blow it off with a bulb syringe. If
the lens needs cleaning, make sure you blow all the dust off the lens before cleaning it.
Dust particles can be hard and scratch glass. So every bit of dust should be removed
before you use a lens cloth. Once the lens is clear of any particles, use lens cleaner on
a Kimwipe or optical cleaning cloth to clean the lens, followed by a dry wipe. Never
spray directly onto the lens as the liquid could migrate around the lens to the inside.

The tube exterior can be cleaned with a lint free cloth and a commercial cleaner like
“Fantastic.” As with any cleaner, follow the instructions on the container.

Your telescope comes with a retracting dews hield. Velvet is used to provide a solid,
smooth motion. Under some climates, the velvet may compress slightly and the dews
hield may slip down when the telescope is pointed upward. In this case, you need to
simply add more velvet. We extra strips of adhesive velvet with every telescope. You
can use these to effectively tighten the dew shield:

1. Remove the dust cover and unscrew the tapered ring
from the dews hield. Turn the ring and not the dews
hield.

2. Slide off the dews hield rotating it clockwise as you
pull it off.

3. Add two or three strips of the adhesive velvet over
the existing velvet making sure the edges are adhered
well to the surface.

4. Replace the dews hield making sure the velvet is fit-
ted under the edge so it does not pull up. Rotate the
shield clockwise as you carefully install it.

5. Screw the tapered ring back onto the rear of the
dews hield.

Note: The dews hield should never be rotated counter-
clockwise when moving the dews hield in or out. This can
start to unscrew the main lens. If this happens, the main
lens can be screwed back into the main tube without con-
sequence but it should be avoided.

Never touch the lens cell retainer located on the front or rear of the lens cell.
