FocusCube 3 from Pegasus Astro: Advanced Solution for Electronic Telescope Focusing

The FocusCube 3 de Pegasus Astro est une solution avancée et autonome pour la mise au point électronique des télescopes, spécialement conçue pour répondre aux exigences croissantes de l’astrophotographie moderne. Voici une description détaillée de ses caractéristiques techniques et fonctionnalités :

Technical specifications

1. High-resolution stepper motor

• Exceptional precision: Angle de pas de 0,0625° grâce à un moteur à engrenages avec un rapport de réduction de 1:120. Cela permet une mise au point à l’échelle du micron, idéale pour des optiques rapides et des capteurs modernes.
• High torque : 60 Ncm, capable of lifting up to 6 kg of imaging equipment, even when the telescope is pointed at the zenith.
• Low backlash: Mechanical backlash is minimized to ensure precise, reliable focusing.

2. Simplified connectivity

• Single USB-C: A single USB-C connection for power and data, reducing the wiring complexity of your setup.
• Extended software compatibility : Support for ASCOM, ASCOM Alpaca and INDI protocols, enabling integration with software such as NINA, SGPro, Voyager, APT and MaximDL.

3. Integrated temperature sensor

• Thermal sensor : An external digital sensor measures ambient and eyepiece holder temperature in real time, automatically compensating for thermal variations to maintain optimum focus.

4. Easily reproducible V-curve

• V-Curve autofocus : FocusCube 3 facilitates the generation of precise V-curves, essential for achieving perfect focus during autofocus.

5. Simple, compact installation

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