2.2. Installing the Azimuth Encoder. Locate the Azimuth Encoder (part #7) and the supplied screws (4 units –part #8) and
fix it to the base with a screw driver (not included) as shown.
Make sure the metal axis on the Azimuth Encoder slides all the way through and that the Azimuth Encoder is flush to the
wood base. Use the screw driver to push the screws and pierce through the wood and fix the screws to the wood base.
Make sure the Azimuth Encoder is placed as shown, parallel to the sides and the connection socket to the opening side.
Insert the original hand knob, supplied with the telescope, through the
hole and tighten it firmly.
Confirm that the Azimuth Encoder is correctly fixed to its axis by
rotating the base.
2.3. Installing the Altitude Encoder and Bluetooth® Box. Now that
you have fixed the Azimuth Encoder, install the Altitude Encoder
and Bluetooth® Box to the base.
Start by releasing the spring friction system on the left-side panel of
the telescope as shown. Use a screw driver (not included) to
remove it. This exposes and frees the side bearing and the base side
plate. This is needed to install the Altitude Encoder and Bluetooth®
Box (part #3).
Keep the telescope’s hand knob aside, it will be needed later. The
spring and the other components should be carefully added to the
other stored items.
When the base is rotated in one direction (for example to the
right), the hand knob should also rotate to the same direction
(right).

2.4. Install the Altitude Encoder and Bluetooth® Box. Align it
to the side panel so that the hand knob slides and aligns with
the side bearing. Keep the Altitude Encoder and Bluetooth®
Box in the up-right position and place the two spacers (part #4)
aligned to the two holes on the bottom so that they are
sandwiched between the side plate and the Box. Use the two
supplied screws (part #5) and the screw driver (not included) to
fix it to the side panel. Apply some pressure to the screws in
order to pierce them through the wood panel.
Tighten the hand knob firmly. Test it like previously done with
the Azimuth Encoder.
Place the tube horizontally and then bring it to the vertical
position. Verify if the hand knob also rotates.
2.5. Connecting the two boxes. Now that the Azimuth Encoder and the Altitude Encoder and the Bluetooth® Box have
been installed to both axes and tested (rotation) it is time to connect both with the supplier cable (part #1).
Connect using the supplied cable. If you hear a “click”,it usually means a good connection!

2.6. Laying the cable. Lay the
cable along the telescope panels
as shown. Cable holders (clips)
are supplied (5 units part #2).
Remove the protective paper to
expose the adhesive and stick it
to the side panel and base circle
as required. Using the clips
insures the cable is not hanging
loose which may be important
for transportation.
3. Installing the Smartphone Holder. The smartphone is an important part of the setup and a smartphone holder was
included. Use the smartphone holder (part #9) and fix it with the two supplied screws (part #10) using a screw driver (not
included). Apply some pressure to the screws so they pierce through the wood. Note that the screws should not squeeze
the metal but allow it to slide if necessary. Remove it whenever required (transportation).
3.1. Adjusting the position of the smartphone. Adjust the smartphone’s
position if necessary (vertical or horizontal position) and fix it using the
supplied hex screw (part #11) as shown.
4. Powerbank and 5V USB to 12V power cable. We have included a powerbank and a power cable with the Push+ Go kit.
Make sure the powerbank is fully charged before using it, please refer to the dedicated instruction manual.
5. Starting the Push+ Go. Before powering, make sure the tube is in the horizontal position as shown.

7. How to pair Push+ to a device or computer?
Pairing is done as you would do with a smartphone or other
device. First power the Push+ by using the supplied power
cable. As soon as Push+ is powered, the red LED will start to
blink. There are two options: you can pair Push+ to an
Android® device (phone or tablet) or to a Windows™ based
Computer.
7.1. Pairing Push+ to a device like an Android®
phone. Make sure your phone is compatible with
Bluetooth 2.0 (or higher).
Step 1
Enable the Bluetooth® option in your device. Do this by
going to the Settings Tab or directly by pressing the
Bluetooth® symbol as shown in figure 26.
Step 2
A window with a list of the available devices will be visible. If you have a previously paired device, it will show
up on the list. If Push+ is powered, it will also show either as Unknown Device or as Push+.
Step 3
Select Push+ from the list and pair it by inserting the 4-digit pairing code.
Each Push+ has its own signature and when pairing, it will “remember” to
which device it is paired. This avoids problems when several Push+ are
working close to one another. Remember the maximum recommended Bluetooth® pairing distance is 10m.
Make sure you are within this distance.
Your Push+ is now being paired to your Android® device.
7.2. Pairing Push+ to a laptop or computer. Make sure
your computer or laptop is compatible with Bluetooth®
2.0 (or higher). There are several ways to pair your Push+ to a computer.
We will describe in the following steps a simple and effective way to do it.
Step 1
Select from Windows™ initial menu the arrow pointing up (show hidden
icons) - red circle (right bottom corner on the screen).
Step 2
Click on the Bluetooth® icon. Select “Add Bluetooth device”.
Step 3
Look for Push+, sometimes it may show up as “unknown device” Click pair.
Step 4
Insert pairing code “1234”.
Your Push+ is now paired with your computer.
Push+ pairing code is “1234”

8. Which software and apps to use?
8.1. SkySafari® from Simulation Curriculum is one of the most popular planetarium app. This planetarium app
shows the sky on a device screen (they have both Android® and iOS versions) and allows telescope control. It
has a huge database with constellations, deep-sky objects, stars, asterisms and many other objects. To know
more visit www.simulationcurriculum.com. SkySafari® is available in several versions from entry level to the
most advanced ones. We recommend using the SkySafari® Plus 4 for Android®. It can be downloaded from the
Google Play® app centre. Please notice, this is not a free app. The free version does not allow controlling
telescopes or Push+. SkySafari® has a quite intuitive interface and is easy to use.

11.1. Connecting SkySafari® App to Push+. Make sure you followed all the steps mentioned above. This is
really important as without this information SkySafari® will not be able to work with Push+. It is very
important at this point to exit the app and re-start it.
Important!
After the settings in 11 are done, please exit the App and re-start it so that SkySafari® applies the recent
changes to the settings!
11.1.1. Connect. Tap “Connect” to connect the telescope to Push+.
Connecting may take some time. When the connection is established,
the red LED stops blinking and remains powered ON.
11.1.2. Cross-hair. As soon as the connection is established, a cross-hair will randomly appear on the
screen. If you move the telescope on both axes, you will see this cross-hair moving accordingly. This is a good
sign; it means both encoders are working. When calibrated, the cross-hair will point to a certain region in the
sky. This region will match the field of view as seen through the telescope eyepiece.
11.1.3. Choosing calibration stars. Alignment is done with one-star or two-star alignment. We recommend the
two-star alignment as it provides a much better pointing accuracy. The two-star separation should be no more
than 30 degrees but no less than 10 degrees - both in Altitude (Alt) and Azimuth (Az). Avoid using alignment
stars close to the horizon and zenith.
Step 1
Centre a bright star - a star that you know or recognize from a constellation - in the
centre of the eyepiece field of view. Follow the rule mentioned above –final
movements always Up and Left. It is important to centre the star in the eyepiece field
of view with some accuracy, we recommend using a cross-hair eyepiece for this
procedure.
Step 2
Match the star to the one shown on the device’s screen. Just swipe the screen so that
the sky rotates and zoom in or out to look for that particular object. Make
sure you know the object matches the one targeted through the eyepiece –
a common mistake is aligning the wrong object. Tap on the star. A small
cross will show on top of the star.
Step 3
Tap “Align” to use that star.
“Align Telescope?”
For a one-alignment star, this is enough. Tap “Align”.
The selected star also named “First Target” or “First Alignment Star” was used
for calibration. You will now see the cross-hair moving across the screen
pointing approximately to the same direction as the telescope.
For additional pointing accuracy, we recommend using a second alignment
star.
Select a second star and align it, make sure it is not more than 30 degrees apart
from the “First Target”.
Alignment should be successful. You are now ready to point to objects using
your Push+.
Rule. Always Up and Left- for consistent results we recommend that the final fine
adjustments to the object, centring in the telescope’s eyepiece, to be made Up –in Alt and
Left –in Az.

12. Troubleshooting with SkySafari®. The most common problems as described below.
Problem
Solution
Cross-hair does not move
If the connection cable is not properly installed, the encoder
position will not be read. Please check the cable connection. Make
sure the hand knobs (both the Azimuth and Altitude are tightened)
and rotate solidary.
SkySafari® gives an error
message when aligning the
second-target
There is a big difference between the position read by the encoders
and the object’s database coordinates. Please make sure you use
the right-hand rule (up-left).
If the problem persists, make sure you are not using a star too close
to the first one.
I get pointing errors higher
than 0.5 degrees
Make sure the two alignment-stars are not separated more than 30
degrees.
Objects are completely off
the FOV.
Wrong star used for alignment.
