Pegasus NYX-01 Harmonic Drive Mount with a Harmonic Gear Drive on both Axis

It can be used in both German Equatorial and ALT/AZ modes. 

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

The Strain Wave drive on RA and DEC movement ensures a backlash-free operation with high torque at high payloads. A fully CNC machined aluminium alloy 6061 body, black and blue anodised, and branded parts (stepper motors, strain wave gear) inside the mount ensure the Nyx-101 will perform flawlessly for many years. 

The mount includes an electronic brake on the RA axis to prevent backsliding when power is off, and safety limit stops during slew or tracking. 

It requires 12V only for its smooth operation, so you can use your standard 12V battery. You won't need an additional converter. The mount consumes less than 0.6 Amps during tracking and up to 2.5 Amps during slewing.

It is supplied with a GX12-type power cable that securely locks onto the mount. Similarly, the USB type B special socket provides a secure grip. Both sockets are placed on the non-movable part of the mount, so there is no cable movement during slews and tracking. A second GX12 cable enables you to power your imaging equipment.

An integrated barometric sensor calculates atmospheric refraction corrections during mount tracking. (For smaller focal lengths, this is probably unnecessary, but if you have an SCT, you will notice a welcome change in your guiding performance).

It includes a low-profile, rigid universal saddle that accepts Vixen and Losmandy-type dovetails.

The back of the mount has an ST-4 port, which is compatible with a simple hand controller or ST-4 guiding camera.

The mount's front includes a place for a QHY Polemaster (not included), enabling you to perform the precise polar alignment required for imaging sessions.

A set of sensors enables you to orient the mount at the correct altitude and azimuth to have an initial, rough, polar alignment (for lower focal lengths such as camera lenses or visual observations ). The Pegasus mobile application guides you through this process.

The design includes reverse voltage polarity protection - a saver if you accidentally reverse battery polarity during the night!

Does not require counterweights for payloads up to 20 kg. However, if you wish to install counterweights for higher payloads, there is a compatible M12 threaded shaft hole at the end of the DEC axis.

The mount fully supports the ASCOM6 and INDI framework. Sky-Safari is also supported, enabling you to control the mount via your mobile device.

LX200 protocol is fully compatible with NYX-101. Sky-Safari works out of the box with the mount.

A mobile application for iOS and Android platforms enables you to control both mount axes, scroll through installed catalogues of thousands of night sky targets, and do a rough polar alignment through an electronic polar assistant.

Safety limit encoders on RA Axis prevent internal cable snags or tripod collisions.

An easy firmware upgrade process enables you to stay updated with bug fixes and the latest features.
