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.
AIM

PRODUCT OVERVIEW
KEY FEATURES
1. High-precision strain wave gears on both axes ensure high payload and a smooth, backlash-
free operation without the need for counterweights for payloads up to 20 Kg
2. Lightweight CNC-machined aluminum alloy AL6061 used for aircraft makes the mount an excellent
choice for your setup.
3. Can be used as a German Equatorial or as an Altazimuth mount.
4. Wi-Fi and USB2 connectivity in the mount can work simultaneously.
5. A power-off brake is installed on the RA Axis and provides an instant safe stop during a planned or
unplanned power interruption.
6. DC 12 Volts Battery Operation with reverse polarity protection
7. Power and USB sockets are placed on the non-movable part of the mount.
8. Mount integrates a barometric sensor required to calculate atmospheric refraction corrections during
sidereal tracking.
9. Universal saddle plate that accepts Vixen and Losmandy 3’’ dovetails.
10. Integrated ST-4 Autoguiding Port.
11. QHY PoleMaster adapter in the front that allows you to place the PoleMaster and perform a quick and
precise polar alignment.
12. ASCOM 6, INDI, LX200 protocol support. Sky-Safari works out of the box with the mount.
13. Safety limits on RA axis. Safety limit sensors on RA Axis prevent internal cable snags.

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.
