ZWO Off-Axis-Guider OAG-L

ZWO Off-Axis-Guider OAG-L: guiding on full-frame format

The OAG-L is the off-axis guider for large sensors and long brand points. The 12 x 12 mm prism captures more than enough light for guide stars—even outside a full-frame field of view—and directs it to a Mini-guide camera. Guiding through the primary optics means tracking without flexure or differential errors.

The optical design is tailored to the ZWO system: OAG-L plus EFW filter wheel plus cooled camera results in exactly 55 mm of backfocus, the standard for most correctors. The included M48 tilt adapter squares the sensor for sharp stars right into the corners.

Features

• Large 12 x 12 mm prism for full-frame guiding
• Exact 55 mm backfocus with EFW and cooled ASI camera
• Included M48 tilt adapter for flat alignment
• No guidescope: less weight, no flexure

Compatibility

Optimized for ZWO EFW filter wheels and full-frame ASI cameras such as the ASI6200 series. Combine with a sensitive mini guide camera like the ASI174MM Mini (wide field) or ASI220MM Mini (highest sensitivity).

Specifications

The OAG-L completes the full-frame train of ZWO: camera, filter wheel, guider and corrector in a rigid assembly.
