This section covers the assembly instruc-
tions for your SVBONY SV501P. Your
telescope should be set up indoor the first
time so that it is easy to identify the various
parts and familiarize yourself with the correct
assembly procedure before attempting it
outdoor.
The SVBONY SV501P comes in one box.
The pieces in the box are – telescope optical
tube, tripod, erect image diagonal, 20 mm
eyepiece, 5x24 finderscope with bracket (all
packed in the travel backpack).
1. The tripod comes preassembled so that the set up is very easy.
2. Stand the tripod upright and pull the tripod legs outward until
each leg is fully extended (Figure 3).
3. You can raise the tripod legs to the height you desire. At the
lowest level the height is about 17.7” (45 cm) and extends to
about 54.3” (138 cm).
4. To raise the height of the tripod, you unlock the tripod leg lock
clamps at the bottom of each tripod leg (Figure 4) by opening the
clamp for each section by pulling outward. Once a clamp is
unlocked, then pull the tripod leg out as far as it will go and then
close the leg lock to secure it. Continue doing this for each
tripod leg and each section to raise the height to the level you
desire. A fully extended tripod looks similar to the image in Figure
5. With all the legs raised up on all sections, the height will be
about 54.3” (138 cm).

◆ATTACHING THE TELESCOPE TUBE TO THE TRIPOD
The telescope optical tube attaches to the tripod by using the mounting bracket on the
bottom of the optical tube and the mounting platform of the tripod. Before starting make sure
all of the knobs on the tripod are locked.
Fig. 5 Fig. 6
Fig. 7
Fig. 8
1. Remove the protective paper covering the optical tube.
2. Loosen the top right knob (Figure 7) by turning it counter-
clockwise.This allows you to tilt the tripod platform up 90° as
shown in Figure 8. After tilting the platform up, tighten the
knob to secure it in place.
3. Figure 9 shows the bottom of the optical tube, the tripod
platform, and where they will attach to each other.
4. Under the center of the tripod platform, you will see a knob
(Figure 9) that contains a ¼ x 20 screw to attach the platform
to the telescope optical tube.
5. You can put the ¼ x 20 screw into the threaded holes of the
SV501P (it doesn’t matter which one you use) in the mount-
ing bracket of the telescope optical tube whereas Hold the
optical tube with one hand while threading the screw clock-
wise until tight with the other hand. Now the assembly will
look like Figure 10.
6. Lastly, loosen the knob for the tripod platform and lower the
platform down to the level position. Then, tighten the knob
securely.

5.If you want to raise the tripod height up further you must use the central column locking knob
which is the knob located at the bottom left in Figure 6. Turn the locking knob counterclock-
wise until loose. Then, pull up on the head of the tripod and the central column will move up.
Continue pulling to the height you desire and then tighten the locking knob. When the central
column is raised up as far as it will go, then the maximum height possible is achieved – 63”
(160 cm)

◆MOVING THE TRAVEL SCOPE MANUALLY
The SV501P is easy to move wherever you want to point it. The up and down (altitude) is
controlled by the Pan Handle Control Knob (Figure 1). The side-to-side (azimuth) is
controlled by the Azimuth Locking Knob (top left knob in Figure 7).
Both knobs are loosened when turned counterclockwise and tightened when turned clock-
wise. When both knobs are loose you can find your objects easily (through the finderscope
which is discussed shortly) and then lock the controls.
◆INSTALLING THE DIAGONAL AND EYEPIECE
The diagonal is a prism that diverts the light at a right angle to the light path of the telescope.
This allows you to observe in a position that is more comfortable than if you had to look
straight through. The SV501P diagonal is an erect image model that corrects the image to
be right side up and oriented correctly left-to-right which is much easier to use for terrestrial
observing. Also, the diagonal can be rotated to any position which is most favorable for you.
To install the diagonal and eyepiece:
1. Make sure the two thumbscrews on the rear of the telescope tube do not protrude into the
opening before installation, the plug up cap is removed from the opening at the rear of the
telescope tube, and the caps are removed from the barrels on the diagonal. Insert the small
barrel of the diagonal all the way into the rear opening of the telescope tube (Figure 11).
Then tighten the two thumbscrews.
2. Put the chrome barrel end of one of the eyepieces into the diagonal and tighten the thumb
screw. When doing this make sure the thumbscrew is not protruding into the diagonal before
inserting the eyepiece.
3. The eyepieces can be changed to other focal lengths by reversing the procedure in step 2
above.

◆INSTALLING THE FINDERSCOPE
1. Locate the finderscope (it will be mounted in the finder-
scope bracket).
2. Remove the knurled nuts on the threaded posts on the
telescope tube (Figure 12).
3. Mount the finderscope bracket by placing it over the
posts protruding from the optical tube and then holding it in
place thread on the knurled nuts and tightening them down.
4. Note that the finderscope should be oriented so that the
larger diameter lens is facing toward the front of the
telescope tube.
5. Remove the lens caps from both ends of the finderscope.

◆ALIGNING THE FINDERSCOPE
1. Locate a distant daytime object and center it in the low power (20 mm) eyepiece in the
main telescope.
2. Look through the finderscope (the eyepiece end of the finderscope) and take notice of the
position of the same object.
3. Without moving the main telescope, turn the adjustment thumbscrews (Figure 12) located
around the finderscope bracket until the crosshairs of the finderscope are centered on the
object chosen with the main telescope.
4. If the image through the finderscope is out of focus, rotate the eyepiece of the finderscope
for a clear view.
Note: Objects viewed through a finderscope are upside down and backwards which is
normal.
◆TELESCOPE BASICS
FOCUSING
To focus your SV501P turn the focus knob located near the rear of the telescope (see Figure
1). Turning the knob counterclockwise allows you to focus on an object that is farther than the
one you are currently observing.
Turning the knob clockwise from you allows you to focus on an object closer than the one
you are currently observing.
Note: Remove the front lens cap of the SV501P optical tube prior to attempting your observa-
tion.
Note: If you wear corrective lenses (specifi cally glasses), you may want to remove them
when observing with an eyepiece attached to the telescope. If you have astigmatism,
corrective lenses should be worn at all times.
◆TELESCOPE MAINTENANCE
While your telescope requires little maintenance, there are a few things to remember that will
ensure your telescope performs at its best.
◆CARE AND CLEANING OF THE OPTICS
Occasionally, dust and/or moisture may build up on the objective lens of your
telescope. Special care should be taken when cleaning any instrument so as not to
damage the optics.
If dust has built up on the optics, remove it with a brush (made of camel’s hair) or a
can of pressurized air. Spray at an angle to the glass surface for approximately two
5

to four seconds. Then, use an optical cleaning solution and white tissue paper to
remove any remaining debris. Apply the solution to the tissue and then apply the
tissue paper to the optics. Low pressure strokes should go from the center of the
lens (or mirror) to the outer portion. Do NOT rub in circles!
You can use a commercially made lens cleaner or mix your own. A good cleaning
solution is isopropyl alcohol mixed with distilled water. The solution should be 60%
isopropyl alcohol and 40% distilled water. Or, liquid dish soap diluted with water
(a couple of drops per one quart of water) can be used.
Occasionally, you may experience dew build-up on the optics of your telescope
during an observing session. If you want to continue observing, the dew must be
removed, either with a hair dryer (on low setting) or by pointing the telescope at the
ground until the dew has evaporated.
If moisture condenses on the inside of the optics, remove the accessories from the
telescope. Place the telescope in a dustfree environment and point it down. This will
remove the moisture from the telescope tube.
To minimize the need to clean your telescope, replace all lens covers once you
have finished using it. Since the cells are NOT sealed, the covers should be placed
over the openings when not in use. This will prevent contaminants from entering the
optical tube.
Internal adjustments and cleaning should be done only by the SVBONY repair
department. If your telescope is in need of internal cleaning, please call the factory
for a return authorization number and price quote.
