Improved Accuracy with NIR Guiding

By utilizing near-infrared (NIR) light for guiding, the ONAG takes advantage of the fact that digital detectors in autoguiders are sensitive to NIR light. Guiding in NIR reduces the effects of atmospheric turbulence and improves active tracking performance, resulting in better auto-guiding accuracy.

Wide Field of View

The ONAG features an integrated X/Y stage that provides a wide FOV for selecting guide stars, allowing for both on-axis and off-axis operations. This enables easy exploration of a large area of the telescope focal plane to find suitable guide stars, unlike most off-axis guiding systems.

Real-time Auto-Focus

The ONAG introduces the SharpLock technology, a patent-pending feature that enables true real-time auto-focus operations. With SharpLock, the telescope remains at the best focus while imaging, eliminating the need for periodic re-focusing and saving valuable time.

*Only Available with SkyGuard

Versatile and High-Quality Design

The ONAG stands out with its exceptional engineering and meticulous craftsmanship. With its well-designed and precisely constructed dichroic beam splitter (DBS), this device ensures reliable and high-quality performance. Its lightweight design further adds to its versatility, making it compatible with a wide range of setups and systems.
