Intro
Thank you for purchasing our products! Prodigy Microfocuser is a robust 3-inch robotic focuser which
allows you to precisely and remotely control the focus of your telescope setup. Its sturdy mechanical
design ensures that Prodigy Microfocuser can lift up to 10Kg of equipment, dead accurate and flexure
free. Focuser has a 25mm of draw tube travel and a clear aperture of 76mm / 3-inch.
Focuser’s drawtube accepts different types of optional telescope adapters such as Celestron SCT Edge,
RC telescopes and refractors.
Prodigy houses 2 x USB2 switchable ports and 2 x 12V switchable power outputs that provide electric
“juice” to your equipment close to the focuser (e.g Filter Wheel, Guiding camera etc).
CONTROLLER CARE
•Controller is protected from moisture but it is not waterproof and it should be kept clean and
dry.
•Excessive moisture for long periods of time can damage electronics and connectors.
•Do not allow solvents or chemicals to come into contact with the device.
•Store controller indoor in a dry room when not in use for long time.
•Do not touch the internal components as they may get hot when in use.

OPERATING INSTRUCTIONS
•Plug the temperature sensor to the “Sensor” socket.
•Plug the USB cable to the “PC” socket.
•Plug any USB2 device to the dual stacked USB2 Ports. Same applies for the 2 x 12V Outputs.
•Plug the power cable into the “12V DC IN” socket.
•Device will boot and after three seconds is going to be fully operational.
•Download USB drivers, standalone software or ASCOM drivers from pegasusastro.com/support
in order to connect to the device.
FOCUSER’s DRAWTUBE
Drawtube has a clear aperture of 3 inches or 76mm. It can travel up to 25mm.
Prodigy Microfocuser isn’t a Crayford neither a Rack & Pinion type. Its innovative mechanical focus
design provides very high load support and accuracy with zero maintenance.
The focuser can easily lift up to 10Kg (22lb) of imaging equipment with zero flexure.
A limit sensor is engaged when the drawtube is fully inside the Prodigy’s body. Limit sensor allows the
user to recalibrate focuser’s position to zero.
ADJUSTABLE ROTATION
Focuser allows adjustable rotation / precise orientation on both sides. This helps you to easily fit the
microfocuser to your telescope and also place your camera with the desired orientation.

POWER INPUT
Controller accepts a voltage range from DC 11.0V –15.0V *
We strongly recommend you use our certified “Pegasus Astro 12V/10A power supply”
•A 13.8V lead (or calcium/lead) battery is also recommended.
•Please use a power supply that can provide at least 2 Amps of current. If you utilize the USB and
Power ports on the side of the focuser you might need up to 8 Amps of current.
Under no circumstance exceed DC 15.0V input as you might cause a severe damage to the electronic
board
Controller has been designed with reverse polarity protection. If you accidentally reverse the power
source polarity, the unit will instantly cut the power. The controller is fitted with a 2.1mm DC power
connection (centre positive pin) which powers on the unit.
Insert the 2.1mm plug on the DC power cable. Controller will initialize and get fully operational after 3
seconds. (The 3 seconds wait time duration is on purpose for a new firmware upload process).
DATA CONNECTIVITY
A USB2 Type B port at the side of the unit accepts the USB cable for PC connection. It is strongly advised
using a branded and shielded USB cable that does not exceed 5 meters /16ft. Plug one end into a spare
USB 2.0 port on the computer or USB Hub, the other end into the USB type B receptacle on the controller
labelled USB-PC.
Controller will be identified as “Prodigy MF revX” and a “USB Serial Port COMx” will be appeared to the device
manager of Windows, under Ports (COM & LPT).
Each device gets a unique serialized COM number (e.g: COM8) so you can simultaneously plug to your PC as many
focusers as you need.

EXTERNAL PORT (EXT)
The controller is fitted with a RJ45 Female Jack for auxiliary usage. In this socket you can ONLY plug the optional
EZY Focus Hand Controller.
IMPORTANT NOTICE:
DO NOT CONECT ANY MOTOR OUTPUT OF AN EXTERNAL CONTROLLER SUCH AS ULTIMATE
POWERBOX OR DUAL MOTOR FOCUS INTO THE RJ45 PORT. THIS WILL CAUSE SEVERE DAMAGE TO
THE DEVICE.
TEMPERATURE SENSOR
The external probe is temperature measurement device which is attached to the controller. It comes with
length of 0.6m cable with a mini stereo jack. Probe measures temperatures from -55°C to +125°C.
Accuracy of the probe is ±0.5°C from -10°C to +85°C. The controller instantly detects during startup the
presence of the probe and requests temperature readings every 30 seconds.
When using multiple controllers and probes, the reported temperature may differ slightly between units
due to small differences between individual sensor readouts. This does not affect the operation of the
units, as they respond to measured temperature change, not to the actual temperature.
Please notice that you have to connect the sensor before you power on the controller. You can also
connect it later but you will need to wait for 15-30 seconds for sensor auto-detection and calibration
12V POWER OUTPUTS
On the right side of the Prodigy Microfocuser there are two (2) 12V DC unregulated outputs. These power
outputs are driven by a dual channel smart mosfet, capable to deliver up to 8 Amps of current (in total).
This mosfet incorporates a broad range of smart features like diagnose and protection. The 12V Channel
can be switched ON/OFF via software. Each 12V power output has the following specification:

DUAL PORT USB2 HUB
Prodigy Microfocuser includes an industrial grade USB hub IC capable to deliver 2 x USB2 High Speed
ports. These dual stacked ports exist on the side of the Prodigy. Both USB ports are controllable and can
be switched ON/OFF via supplied software.
These USB ports allow the connectivity of equipment close to the Prodigy focuser such as a Filter Wheel,
a guiding camera, a motorized OAG etc.
MOTOR OPERATION
Prodigy Microfocuser has an embedded stepper motor. Its rotation is driven via a belt and pulley system
to the focuser’s drawtube. Stepper motor design ensures a smooth, low noise and backlash
free operation. V-Curve points during automatic focus procedure are dead accurate.
•Focuser has been (factory) configured to perform position steps from 0 -> 11000
•Each step movement is 0,0227 mm / 2.27 micron
RESET WATCHDOG
A hardware watchdog resets the device if for any reason there is no response from the controller after
two (2) seconds. A neat feature in the unlikely event of a microcontroller freeze –when have a remote
observatory and you need to be sure that everything works as expected.
OPERATION LED
A red colored LED is fitted on the centre of the Prodigy enclosure. Every time the motor is moving the
LED lights on to indicate that Focuser is sliding in or out. When motor is idle, led turns off to avoid any
light reflection inside the focuser.
RECOMMENDATION
•It is advised to select and use good quality and short length USB cables.
•Do the same for power cables. Long and thin power cables will have an effect of voltage drops.
This can cause issues to your camera (CCD or CMOS) image quality or mount tracking.
