20 Technical Characteristics of STELESCOPE 70
Congratulations on your purchase of this STELESCOPE 70 telescope!
Stelvision's STELESCOPE range has been designed to make quality sky
observations as simple as possible. This manual will give you the explanations
you need to simply and easily learn about your telescope and make your first
observations. Read it carefully. We are at your service for any questions that
may remain after you’ve read these pages (see p. 20).
Happy observing,
The Stelvision Team
This instruction manual is to be considered an integral part of the telescope. Please read it carefully,
making sure to understand the safety instructions before use. Keep this manual for the entire service
life of the telescope and attach it to the telescope in the event of resale or transfer.
CAUTION: RISK OF PERSONAL INJURY
RISK OF BLINDNESS: Never look directly at or near the Sun through the telescope without a
specific sun filter, as this may cause irreversible damage to your eyes. Children should only use the
telescope under adult supervision.
DANGER OF SUFFOCATION: Keep packaging materials (plastic bags, rubber bands, etc.) out of the
reach of children.
FIRE HAZARD: Never leave the telescope, especially the lenses, exposed to direct sunlight. The
magnifying glass could cause fires.

The letters refer to the indications in the images on the left of each
page. The capital letters also refer to the description of the items
on page 5.
TRIPOD SET UP
1. The telescope mount includes the tripod with adjustable
legs, its mount and accessory tray . Extend the legs of the
telescope and lock them in place by tightening the knobs
.
Stand the tripod upright and gently pull the tripod legs
apart until the center brace snaps into place horizontally. Adjust
the length of the feet if necessary.
2. Position the accessory tray so that its central hole can be inserted
over item at the center brace line.
3. Rotate the tray until the tabs clip into the pins on the three
leg braces.
6. Screw the panning handle onto the mount.

PLEASE NOTE: Although not essential, the accessory tray helps
reinforce the telescope and increases the stability of the images
provided by the optics.

OPTICAL TUBE PLACEMENT
The optical tube is attached to the mount by means of a dovetail
bar. This trapezoid-shaped metal part is inserted into the slide rail
located on the telescope clamp at the top of the mount.
5. Loosen the two knobs of the slide rail until the passage is
completely free.
6. Position the telescope clamp horizontally and tighten the
panning handle and the azimuth tension knob . Insert the
dovetail bar of the tube into the slide rail and tighten the
knobs .
INSTALLING THE ACCESSORIES
The Red Dot Finder
The STELESCOPE 70 is equipped with a red dot finder which
helps point celestial objects.
7. Set up the red dot finder lens so that it is positioned towards the
front of the tube. Insert the finder on the base found at the rear of
the optical tube and tighten the clamp screw. Remove the plastic
tab under the battery cover before use.
The Eyepiece Holder and Star Diagonal
8. Remove the cap from the eyepiece holder and insert the Amici
prism star diagonal . Tighten the clamp screws .
Dust Caps
9. Dust caps must always be in place when STELESCOPE 70 is
not in use in order to limit dust deposits on the optics as much as
possible. There are two caps: the eyepiece holder cap which can
also be used on the star diagonal in the absence of an eyepiece
(see picture) and the optical tube cap to be placed at the front
of the tube.

Before you use your STELVISION 70 for the first time, carry out
the following adjustments in day light for the best results. You
will be able to do this at night just before observations once you
have a better understanding of your telescope.
MOTION
The azimuth tension knob must be just tight enough to allow for
smooth, frictionless movement from left-right. Once this tightness
has been adjusted, the panning handle can be used to maneuver
the STELESCOPE 70. This handle, located on the altitude axis that
moves up-down, makes swiveling the optics possible. The handle
should be unscrewed when maneuvering the telescope. It must be
tightened (without over-tightening) before release to ensure that
the tube remains stationary.
POINTING
Always use the eyepiece with the lowest magnification, i.e., the one
with the longest focal length (20 mm), to make pointing easy.
Pointing can be done by moving the tube via the panning handle.
To do this, aim at the target by placing your eye along the tube or
by using the red dot finder. (Make sure that the red dot finder is
correctly aligned: see Aligning the Red Dot Finder paragraph on
p.10).
Tighten the panning handle to lock the tube in place.
Twist the knob until focus is reached (see the following section),
and then center on
the target in the eyepiece with more precision
by operating the height adjustment lever.
EYEPIECE PLACEMENT AND FOCUSING
To guarantee the quality of the images delivered by
STELESCOPE 70, the focus, i.e. the sharpness of the image, must
be properly administered. This can be done by turning the knob
located at the rear of the eyepiece holder. Choose a distant object
and point the telescope at this object to focus your eyepiece for the
first time (if the distance is too short, focusing will be impossible).
10. Insert an eyepiece and tighten the clamp screw.
Place your eye on
the eyepiece and turn the focus adjustment dial
gently in one direction
until you find the sharpness range. If this does not work, turn the
dial in the other direction.
Once you find the sharpness range, you can refine the focus quality.
To do this, turn the dial back and forth to "frame" the area. Each
overshoot in either direction will be gradually reduced until you
stop at the sharpest point. This method will prevent your eye from
getting used to an otherwise blurry image. It naturally compensates
for an approximate focusing, but it makes the observation much
less comfortable and leads to faster eye fatigue. The back and
forth movement of the eyepiece holder's dial deceives the eye
and makes it easy to find the right focus.
Please note that the eyepiece holder is equipped with a clamp screw
which must be tightened just enough to allow smooth focusing.

UNDERSTANDING IMAGE ORIENTATION
11. The STELESCOPE 70 telescope is a refractor, which means
that it made up of lenses. Light passes through these lenses and
then through the eyepiece, which is also composed of lenses.
You can insert an eyepiece
directly behind the optical
tube. In this case, the image
will appear inverted (both
upside-down and left-right
direction).
It is better to add a star
diagonal to the telescope,
which makes viewing much
more comfortable. This
accessory is equipped with
an Amici prism optical
system which flips the image on both ends. This is particularly useful
if STELESCOPE 70 is used for daytime terrestrial observing.
RED DOT FINDER ALIGNMENT
The red dot finder is necessary to center on the celestial objects
in the telescope. It therefore must be perfectly aligned with the
optical tube to work.
12. The red dot finder does not magnify the image. It is made up of
a window which displays an illuminated red dot. Stand behind the
finder while keeping both eyes open to use it.
Aim the tube at an easily recognizable object, such as the top of
a pole, which should be as far away as possible (at least twenty
meters).
Once the target is in the 20 mm eyepiece, center on the top of the
pole via the panning handle. Then repeat this by replacing the 20
mm eyepiece with the 9 mm eyepiece.
Turn on the red dot finder and look through (set the intensity to its
maximum level if you are in a lit area).
13. The red dot must be placed on your target. If this is not the
case, use the two knobs to adjust it.
Check that the target is still centered in the eyepiece's field of view
after adjusting the finder. If not, repeat steps 12 and 13.
