PREFACE
INTRODUCTION
Thank you for purchasing the Pegasus Astro NYX-101 Mount.
Strain wave drive technology results in a smooth, backlash-free mount operation with extremely high torque,
without the need for counterweights. A fully CNC machined aluminum 6061 and stainless-steel body, black and blue
anodized, and a selection of branded internal parts, ensure that Nyx-101 will perform flawlessly for many years.
This hybrid combination of a stepper motor & belt system along with sophisticated electronics drives the Right
Ascension axis down to 0.10 arcseconds of resolution. Mount has an electronic brake on the RA axis to prevent
backsliding when power is off as well as safety limit stops during slew or tracking.
NYX-101 is compatible with ASCOM, INDI, and any software that supports the LX200 command set.

PACKAGING
Mount comes inside a hard-shell carry case. All parts are specially packed inside this case. When you receive your
new NYX-101 mount, pay attention to check that no part has been damaged during shipment.
MOUNT CARE AND HANDLING
▪Handle the mount like a precision instrument.
▪Excessive moisture for long periods can damage electronics and connectors.
▪Do not touch the power cords with wet hands. There is a risk of electric shock.
▪Never touch the internal electronic board as it produces high voltage and may get hot when in use.
▪Do not disassemble or modify the product. The product may be damaged.
▪Do not allow solvents or chemicals to come into contact with the device. Wipe the mount with a soft cloth.
▪Mount electronics are not waterproof and they should be kept clean and dry.
▪Store mount indoors in a dry room when not in use for a long time (preferably inside the carry-on case).
▪Mount does not require re-greasing on both strain wave gears or any other internal mechanical part.
▪Re-greasing the pitch elevation mechanism might be required after a long time of usage.
▪The load capacity of the mount is 20 kg without counterweights (30 Kg with counterweights). Overloading the
weight can cause damage to the mount.
▪Telescope equipment is usually heavy, so be careful not to drop it when transporting or installing.
▪Persistent rubbing with a cloth on logo marking areas may wear them.
HIGH TORQUE WARNING
NYX-101 produces very high torque on both axes which can be dangerous if cables, your hand fingers
or any other obstacle collide with the mount or stuck between moving parts!
In this unlike event, mount can easily crash or cut anything that is left unattended. Mount parts can
also get damage due to the strong torque.
Take extra care of your gear, setup mount limits and most important, do not touch the mount when
in slew.

MOUNT KEY POINTS
[1]
Dovetail Saddle and Clamp Knobs: Saddle is compatible with Vixen and Losmandy 3-inch dovetails.
Use the two knobs or insert an Allen hex tool (5mm hex key) to grip your telescope onto the saddle.
[2]
Altitude Tensioner: Loosen this knob to adjust the altitude knob of the mount and fasten again when after
completion.
[3]
Altitude Adjustment Knob: Use this knob to adjust the mount altitude (pitch) from 0-90 degrees.
[4]
Azimuth Adjustment Knobs: Rotate these two knobs to adjust the azimuth base of the mount (± 5 degrees).
[5]
Azimuth Locking Knobs: Tighten to secure the mount in the azimuth base.
[6]
Counterweight Shaft Screw: Remove this cap and use this thread to place an M12 countershaft and install
counterweights.
[7]
Accessory Holes: These M4 holes on each side allow you to securely attach accessories to the mount’s body.
[8]
Polarscope camera screw holes: A QHY PoleMaster adapter is already installed onto the mount. Use this hole pattern
to install the polar scope camera onto the mount.

Pegasus Astro –NYX-101 Product Manual
All electronics and connections are integrated into the non-moving part of the mount and are accessible from the
back of it.
[8]
12V Power Input: The GX12 type socket ensures a secure, lockable connection. Use the included PSU (12V/5A) to power
on the mount.
[9]
12V Power Output: The GX12 type socket ensures a secure, lockable connection. The input voltage is passed through
this output. This output can deliver up to DC 12V/7Amps (for this purpose, a higher power PSU is required).
[10]
USB Socket: Connects the mount to your PC via a USB2 interface.
[11]
ST4 Guiding Port: Connect an ST4 camera for mount guiding in this port. This EXT port has a multipurpose role and
can be used to plug a modern hand controller with a display (available soon).
[12]
Red LED Indicator: Light blinking pattern shows different mount states.
[13]
Power Switch: Turns on and off the mount.
Mount connections should be established before turning ON the mount, to avoid the risk of
damaging the electronics. The USB port is an exception and can be plugged or unplugged when
mount is in operation.
As the mount steps up the input voltage up to 42V DC it is important that you will not undervalue
the risk of electric shocks.
Keep this mount back plate clear of dew and water.

BASE PLATE -TRIPOD ADAPTER
Before attaching the base plate adapter (PEG-ADAPT101-XXX) to any tripod, you must install the azimuth dowel
required for the azimuth fine adjustment of the mount.
1. Locate the two small screw holes (M3) at the side of the tripod adapter.
2. Place the azimuth dowel (figure below) and secure it with the two supplied M3 Allen hex screws (use a
2.5mm Allen hex key).
•Use the M10 bolt (you will need an 8 mm Allen hex tool) to stack the EQ6 adapter with the aluminium
tripod base. (figure below)
•Use the EQ6 stock M12 shaft and pass it under and through the EQ6 adapter. Secure the mount head by
tighten it into the M12 thread of the mount.
If you own an EQ6 compatible tripod, you must unscrew and store safely, the stock metal dowel.

In order to attach the mount head directly to the EQ6 tripod you have to extend the M12 central thread of mount
base. Use the M12 male to female extension bolt (included with PEG-ADAPT101-EQ6 adapter) and attach it on the
M12 female thread as in figure below. (no special tool is required).
This is how it should look (figure below)
