ZWO OAG-L Large Off-Axis Guider

Product Description 

The ZWO OAG-L Large Off-Axis Guider is designed for precise guiding in astrophotography setups using full-frame and APS-C cameras. Its large 12 × 12 mm prism captures more guide-star light, while the rigid aluminum construction helps minimize differential flexure for accurate long-exposure imaging. With a 17.5 mm thickness and compatibility with ZWO’s 2" and 36 mm filter wheels, the OAG-L is an excellent choice for advanced deep-sky astrophotography setups.
