Pegasus Astro NYX-88 Harmonic Gear Mount
Harmonic Gear Drive on both axes
The Pegasus Astro NYX-88 Harmonic Gear Mount features two axes of harmonic gear drive.
The NYX-88, developed with travelers in mind, has an exceptional payload capacity of up to 14 kg (mount weighs 5 kg) without the need of counterweights. This mount is designed for precision and performance in astrophotography and observational astronomy, ensuring smooth and consistent operation.
The NYX-88 boasts strain wave drives on both the RA and DEC motions, ensuring a backlash-free experience with high torque even at maximum weights. Its entirely CNC machined aluminum alloy 6061 body, anodized in black and blue, combines durability and style. Inside, you’ll discover high-quality branded components, such as stepper motors and strain wave gears, to ensure the mount’s long-term reliability.
The mount also has an electrical brake on the RA axis to prevent backsliding when the power is turned off, as well as safety limit stops for slewing or tracking. Whether you’re exploring the night sky from your home or a remote area, the NYX-88 is the ideal companion for travelers looking for precision and dependability in their astronomical adventures.
Lightweight & Powerful
Lightweight Design with Impressive payload capacity.
Aircraft-Grade Build, CNC-machined aluminum alloy AL6061.
Compact: Mount weighs just 5 kg.
High precision strain wave gears
Harmonic Gears on Both Axis ensure high payload capacity and a smooth backlash-free operation.
Combining a stepper motor and belt drive with sophisticated electronics, the RA axis achieves a remarkable 0.15 arcseconds of resolution, offering very low periodic error for ultra-smooth and stable tracking down to subarcsecond accuracy.
Supporting high imaging loads for its class
Counterweights are not required for payloads up to 14 Kg (31 lbs).
With a weight of 5 kg, the mount supports a payload of up to 14 kg, demonstrating a high load-to-weight ratio.
However, they can be installed for higher payloads by using a counterweight rod.
Equatorial or Altazimuth Mode
Versatile Mount: Use as German Equatorial or Altazimuth.
Switch Modes Easily: Via PC, Hand-Controller, or Mobile App.
Power Off Brake
RA Axis power-off brake ensures an instant safe stop during any power interruption.
Built-in Wireless & USB operation
Seamless Connectivity: Wireless and USB2 supported simultaneously.
Wide Compatibility: Works with ASCOM Alpaca, ASCOM, INDI, and LX200 protocols.
Additional Key Features
DC 12 Volts Battery Operation
The NYX-88 requires only 12V for smooth operation, allowing you to use a standard 12V battery without additional converters. The mount consumes less than 0.6 amps during tracking and up to 2 amps during slewing.
Universal Saddle Plate
The NYX-88 includes a low-profile and rigid universal saddle that accepts Vixen and Losmandy 3-inch dovetails.
Integrated ST-4 Autoguiding Port
An ST-4 port is available, compatible with our dedicated NYX hand controller or an ST-4 guiding camera.
DC Output
At the side of the mount an extra DC (GX-12) output can provide up to 8A to your equipment sitting on top of the NYX-88 mount.
Reverse Voltage Polarity Safety
NYX-88 has been designed with reverse voltage polarity protection. A saver if you accidentally reverse voltage or battery polarity during the night.
Optional Counterweight support
The mount does not require counterweights for payloads up to 14 kg. However, if you need to install counterweights for heavier payloads, there is a compatible M12 threaded shaft hole at the end of the DEC axis.
Auto Home Slew
The automatic home position feature is implemented with encoders on both axes.
ASCOM & INDI
The mount fully supports ASCOM 7, ASCOM Alpaca and INDI framework. Sky-Safari is also supported allowing you to control the mount through your mobile device.
LX200 Compatibility
LX200 protocol is fully compatible with the NYX-88 mount. Any device that support LX200 such as Sky-Safari works out of the box with the mount.
Mobile Control
A mobile application for IOS and Android platforms allows you to control both axes of the mount, slew to installed catalogs of thousands of night sky targets and do a rough polar alignment through an electronic polar assistant.
Safety limits on RA axis
Safety limit encoders on RA Axis prevent internal cable snag or collision with the tripod.
Firmware Upgrade
An easy firmware upgrade process allows you to stay up to date with bug fixes and the latest features of the mount.
