Pegasus NYX-101 Harmonic Gear Mount

Nyx, the ancient Greek goddess of the night, enlightened us to design and produce a high-performing, high payload mount that can easily carry imaging equipment up to 20Kg without needing a counterweight or shaft.

Strain wave drive on RA and DEC movement ensures a backlash-free operation with high torque at high payloads. A fully CNC machined aluminum alloy 6061 body, black and blue anodized, and a selection of branded parts (stepper motors, strain wave gear) inside the mount, ensure that NYX-101 will perform flawlessly for many years. Mount includes an electronic brake on the RA axis to prevent backsliding when power is off as well as safety limit stops during slew or tracking.

High precision strain wave gears

Harmonic Gears on Both Axis ensure high payload and a smooth, backlash-free operation. A hybrid combination of a stepper motor belt system along with sophisticated electronics can drive RA axis down to 0.10 acsecs of resolution. Reduction on RA axis is 500:1 and 300:1 on DEC axis.

Supporting high imaging loads

Counterweights are not required for weights up to 20Kg. Counterweights can be installed for higher photographic loads – compatibility with M12 shaft.

Lightweight Design

Lightweight Design, compared to the payload of weight the mount can lift.

CNC machined aluminum alloy AL6061 used for aircraft makes the mount an excellent choice for your setup.
Mount weights 6.4 Kg

From a small refractor to a fully loaded SCT 11-inch telescope, NYX-101 can easily handle the payload

Equatorial or Altazimuth Mode

Mount can be used as a German Equatorial mount or as an ALT/AZ, more suitable for visual observations The mode can be switched from our PC or Mobile Application

Built-in Wireless & USB Control

NYX-101 support wireless and USB 2 connectivity out of the box.
Both technologies can work simultaneously.

Mount is compatible with LX200 protocol and Sky Safari for mobile interaction

Power Off Brake

A safety power-off brake is Installed on the RA Axis and provides an instant safe stop
during a planned or unplanned power interruption.

Optional Accessories - Pegasus Carbon Fiber Tripod

This is the Pegasus Carbon Fiber Tripod for NYX-101 Harmonic Drive Mount (PEG-TRPD101).

The tripod legs are rigid and lightweight, made from carbon fiber. We strongly suggest using this tripod with imaging equipment for up to 15Kg.

• Length Retracted: 65 cm
• Max length: 120 cm
• Weight: 2000 gr
• Max Load Capacity: 50kg
• Angle of Legs: 35° Fixed

Half Pier Extension 180mm

A pier extension ( 18 cm / 7” is available). The pier can be easily constructed by purchasing the three (3) following parts:

1. EQ6 / Universal adapter
   (PEG-ADAPT101-EQ6) 
2. Aluminium Standoffs – 3 pcs
   (PEG-ADAPT101-STDOFF)
3. Carbon Tripod Adapter
   (comes along with our 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).

Assembly / Usage Scenarios

Note: You also have the option to discard the pier extender and place the NYX-101 directly on a tripod/pier by using only the Universal /EQ6 Adapter (PEG-ADAPT101-EQ6)
This scenario is most appropriate when you have a small refractor setup that does not require a pier extender

This is a classic example of using your Aluminium EQ6 Tripod with our Half Pier Extension along with 2 x PEG-ADAPT101-EQ6 adapters.

The real deal!

We loaded a refractor (A Takahashi FSQ85-ED @ 450mm) on the NYX-101 harmonic geared mount and a CMOS camera QHY268C along with other astrophotographic equipment. The payload was 8Kg / 17.6lbs. Guiding was achieved via an off-axis guider and QHY-5III Series camera.

Moreover, we tried the extreme scenario and loaded our Celestron EdgeHD 11”with imaging equipment. (Prodigy Micro focuser, QHY268M, QHY-OAG, QHY 5III Guiding camera Pegasus Indiigo 7 pos Filter Wheel) in our backyard. The total payload is 18kg and the focal length remains default at 2800mm.

The real deal is the two images below from our actual tests during long cloudless nights.

1. An image from NINA with unguided results from an 120-sec exposure at 2800mm
2. PHD2 guiding graphs from the OAG guider. The guiding exposure interval is every 2 seconds.
