QHY Q-Focuser

QFocuser comes in two versions: Standard Version and High Precision Version.

The Standard version is designed to be installed on the side of the standard adjustment axis of the telescope focusing mechanism. This is the same with most focusers available in the market. The High Precision version is installed on the other side — the precise adjustment axis of the telescope focusing mechanism.

If you need the ability to manually tweak focus after installation, the High Precision version may be the better fit. But for most astrophotographers, the Standard model offers the ideal balance of performance, payload capacity, and value.

QHY Q-Focuser Standard

• Lightweight & Compact: Just 43 × 39 × 50 mm and 210 g
• Strong Payload: Supports up to 10 kg, perfect for heavy imaging trains
• Precision Motor Control: Uses a reduction motor; small backlash can be corrected in software such as NINA or ASCOM autofocus routines
• Temperature Compensation: Built-in external sensor adjusts focus as conditions change
• Flexible Power: Run from USB-C (5 V) for portable setups or 12 V DC for extra torque

Best for: Astrophotographers who want reliable, automated focus at an affordable price, with simple installation and strong load capacity.
