Pegasus Astro NYX-88 Harmonic Gear Mount

Pegasus Astro NYX-88 Harmonic Gear Mount

Pegasus Astro is excited to unveil the latest addition to their NYX harmonic mount series: the NYX-88, a compact mount designed to complement its larger sibling, the NYX-101.

The NYX-88, designed with travelers in mind, offers an impressive payload capacity of up to 14 kg (mount weighs 5 kg) without the need for counterweights. Engineered for precision and performance in astrophotography and observational astronomy, this mount ensures seamless and reliable operation.

Featuring strain wave drives on both the RA and DEC movements, the NYX-88 guarantees a backlash-free experience with high torque even at maximum payloads. Its fully CNC machined aluminum alloy 6061 body, anodized in black and blue, combines durability with aesthetics. Inside, you´ll find top-quality branded components, including stepper motors and strain wave gears, ensuring the mount´s long-term flawless performance.

The mount also includes an electronic brake on the RA axis to prevent backsliding when the power is off, as well as safety limit stops during slewing or tracking. Whether you´re exploring the night sky from your backyard or a remote location, the NYX-88 is the perfect companion for travelers seeking precision and reliability in their astronomical pursuits.


Main Features

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 axes ensure high payload 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.

Reduction on RA axis is 400:1 and 300:1 on DEC axis.

Supporting high imaging loads for its class

Counterweights are not required for weights up to 14 kg (31 lbs).

Counterweights can be installed for higher payloads by using a counterweight rod - compatibility with M12.

With a weight of 5 kg, the mount supports a payload of up to 14 kg, demonstrating a high load-to-weight ratio.

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 and USB Control

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 mount requires only 12 V for smooth operation, allowing you to use a standard 12 V battery without additional converters. The mount consumes less than 0.6 amps during tracking and up to 2 amps during slewing.

Secure Power
The power cable is a GX12 type which can securely lock onto the mount. The socket is placed on the non-movable part of the mount. No cables moving during slews and tracking.

Reverse Voltage Polarity Protection
NYX-88 has been designed with reverse voltage polarity protection. A saver if you accidentally reverse battery polarity during the night.

DC Output
An extra DC (GX12) output on the side of the mount provides up to 8 A to your equipment.

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 at the back of the mount, compatible with a dedicated NYX hand controller or an ST-4 guiding camera.

Polemaster Adapter
In the front of the mount, there is a place for the QHY Polemaster (adapter included), which allows you to perform a precise polar alignment, required for your imaging sessions.

Optional Counterweight Support
The mount does not require counterweights for up to 14 kg of payloads. 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
The 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 collisions 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.


ASCOM Alpaca Native Support

ASCOM Alpaca outshines classic ASCOM drivers with its platform independence, modern web standards, streamlined installation, remote control capabilities, extensibility, and open-source options. This ensures superior compatibility and user-friendly performance, making it the preferred choice for advanced astronomy applications.

The NYX-88 comes equipped with an integrated web server that seamlessly communicates with Alpaca clients natively. This integration enhances the user experience by providing easy and driverless access to mount control through ASCOM Alpaca.

Modern imaging software like N.I.N.A. automatically identifies native Alpaca devices and lists them for immediate use.


Unity Platform

NYX mounts are controlled and fully configured through Pegasus Astro´s Unity Platform via USB or Wi-FI channel. The included ASCOM driver supports multiple clients.


Optional Accessories

Pegasus Carbon Fiber Tripod
With its rigid and lightweight carbon fiber legs, the tripod can be used with imaging equipment for up to 15 kg. Some data:

Length retracted: 65 cm

Max length: 120 cm

Weight: 2000 g

Max load capacity: 50 kg

Angle of Legs: 35° fixed

Half Pier Extension 180 mm
The pier can be easily constructed by purchasing the three (3) following parts:

1. EQ6 / Universal adapter (PEG-ADAPT101-EQ6)

2. Aluminum standoffs - 3 pcs (PEG-ADAPT101-STDOFF)

3. Carbon Tripod Adapter (comes along with the Carbon Tripod PEG-TRPD101).

Note 1: If you do not own the carbon tripod then the EQ6 / Universal Tripod Adapter can be doubled to assemble the half-pier extension.
Note 2: Three (3) additional standoffs can be purchased to increase pier stability (Half Pier accepts up to 6 standoffs).
