QHYCCD OAG-PRO Versions: Advanced Off-Axis Guiding for Astrophotography

Key Features:

• Shared Field of View: The OAG-PRO versions allow the guiding and imaging cameras to share the main optical system's field of view, crucial for precise astrophotography.

• Ideal for Long Focal Length OTAs: Especially beneficial for setups with long focal length OTAs, where finding suitable guide stars in the FOV can be challenging.

• Enhanced Guide Star Capture: Using guide cameras with larger sensors, like the QHY5III174M or QHY5III585C, increases the FOV and the likelihood of capturing more guide stars.

• Optimized Prism Size: Features a wider prism (10 x 14mm) compared to the standard 8 x 8mm in QHYOAG series, minimizing vignetting and enhancing performance with large sensor guide cameras.

• Solid and Reliable Connection: Directly attaches to the camera or filter wheel with six screws for a stable, parallel, and reliable mechanical connection.

• Flexible Accessory Compatibility: Compatible with various standard and optional QHY accessories, allowing for diverse structural combinations.

• Prism Position Adjustment: Includes a prism position adjustment locking knob for precise placement relative to the chip, ensuring no image obstruction.

• Helical Focusing Seat: Features a helical focusing seat for fine adjustments to the camera’s focal plane, with a locking knob to secure the focus.

• Guiding Camera Compatibility: Designed to work in tandem with a guiding camera, ensuring equal distances from the prism’s surface to both the guiding camera and the imaging CCD.

• Focus Adjustment Tips: Users are advised to adjust the focus carefully, avoiding forceful rotation when the focusing ring is locked to prevent damage.

• Included Adapter Kits: Comes with Adapter B1 Kit for QHY268M and QHY600M-PH SBFL, and Adapter G1 Kit for QHY268C and QHY600C-PH SBFL models.

• Protective Film Reminder: Users should remove the protective film on the prism before use to ensure clear guiding and imaging.
