QHYCCD Q-Focuser : Electronic Focusing Motor
The QHYCCD Q-Focuser is a compact, precise electronic focusing motor designed to automate telescope focusing. Available in two versions - Standard and High Precision - it adapts to a wide range of configurations and offers advanced performance for demanding astrophotographers.
Main Features
- Two versions are available:
- Standard version : Designed for installation on the coarse adjustment shaft of the focusing mechanism. This version uses a geared motor, ideal for loads of up to 10 kg.
- High-precision version : Installed on the fine-adjustment shaft, it incorporates a gearless motor. It allows manual focusing even after installation, without the need for a power supply or clutch switch. This version virtually eliminates backlash, offering optimum precision.
- Compact and lightweight:
- Dimensions : 43 x 39 x 50 mm, making it smaller than most focus motors on the market.
- Weight : Approx. 210 g (Standard Version) and 265 g (High-Precision Version).
- Extended compatibility :
- Supports Windows (ASCOM) and Linux systems.
- Compatible with third-party software such as NINA for smooth automated settings.
- External temperature sensor included : Automatically adjusts focus according to temperature variations.
- Flexible power supply : Operates via USB (5V) or external power supply (12V), as required.
Distinctive advantages
- Increased precision with the High Precision version:
- Thanks to its gearless motor, this version virtually eliminates mechanical backlash, guaranteeing smooth, precise focusing.
- Allows manual focusing after installation, a rare feature among electronic focus motors.
- Versatile installation : Multiple mounting options thanks to multiple holes on the Q-Focuser body, offering maximum compatibility with various telescopes.
- Compact, elegant design: Its small size and curved design enable it to be adapted to configurations where larger motors would be unsuitable.
- Reliable performance at high loads: The Standard version supports up to 10 kg, while the High Precision version can handle up to 7.5 kg.
Applications
- Automated astrophotography : Ensures precise focusing to capture sharp images.
- Advanced guidance : Compatible with software such as NINA for smooth automatic adjustment.
- Visual observations : Allows direct control without a computer, with a manual controller to follow.
Conclusion
The QHYCCD Q-Focuser is a compact, high-performance solution for automating the focusing of your telescope. Whether you choose the Standard version for its robustness or the High Precision version for its unique flexibility and absence of mechanical backlash, this motor is designed to meet the needs of modern astrophotographers while remaining easy to install and use.
