Pegasus Astro FocusCube Zero : Advanced Focusing Motor

The Pegasus Astro FocusCube Zero is an advanced electronic focusing motor, specially designed for Schmidt-Cassegrain (SCT) or RASA telescopes. This self-contained device offers exceptional precision and ease of use, meeting the needs of demanding astrophotographers. Here's a detailed description of its technical features and functions:

Key features

1. High-precision stepper motor

• Bipolar stepper motor : Zero backlash movement guarantees precise, reproducible focusing, essential for high-resolution astrophotography.
• Fast travel : The absence of a reduction gearbox allows quick adjustments of the primary mirror, ideal for rapid focus adjustment.

2. Stand-alone digital control

• Total autonomy : The device incorporates its own electronic controller, so there's no need to connect an external controller.
• Software compatibility : Can be controlled directly from a PC using ASCOM drivers or Pegasus Astro's Unity platform, compatible with popular software such as NINA.

3. Integrated thermal sensor

• Continuous temperature measurement : The built-in sensor automatically adjusts focus to compensate for temperature variations, maintaining optimum sharpness throughout sessions.

4. Easily reproducible V-curve

• Autofocus precision : FocusCube Zero facilitates the generation of precise V-curves, essential for achieving perfect focus during autofocus.

5. Simple, compact installation

• Compact design: Measuring 52 x 58 x 35 mm, it is easily installed on the SCT telescope's focuser using a dedicated bracket.
• Cables included : The device is supplied with the necessary power and USB cables.

Practical benefits

• Universal compatibility : Designed specifically for SCT telescopes such as the Celestron C11 and EdgeHD.
• Increased reliability : Modern materials and advanced electronics guarantee durability and consistent performance.
• Ease of use : Once installed, simply connect the device to the PC, download the necessary drivers, and it's ready to go.
• Full autonomy : No need for a physical remote control or additional accessories.

Limitations

• Connectivity : Must not be connected to external controllers such as the Dual Motor Focus Controller or Ultimate Powerbox via the RJ45 port, which is reserved solely for the thermal sensor or an optional remote control.
• No physical remote control : A physical remote control is not included in the purchase.

Applications

• Astrophotographers looking for precise automated focusing on SCT telescopes.
• Users wishing to minimize vibration during manual adjustment.
• Long sessions requiring automatic temperature compensation.

Conclusion

In short, the Pegasus Astro FocusCube Zero is distinguished by its precision, speed and ease of installation, making it an essential tool for optimizing the focusing of SCT telescopes under demanding conditions.
