Specifications

Why Choose ZWO OAG?

Excellent Stability

ZWO Off-Axis Guider (OAG/OAG-L/OAG-L-68)is made of aluminum alloy, lightweight and elegant with moderate thickness, and features a set screw to secure the prism column, for firm and stable connection. 

High Precision

ZWO Off-Axis Guider can connect both main camera and guide camera simultaneously, eliminating the need for a separate guide scope. It uses part of the light path from the main telescope for guiding, providing higher precision.

ZWO 1.25″ Dual-Focuser (Sold Separately)

When using OAG, pair with ZWO HF Dual-Focuser, for easy and precise focusing. The HF focuser is made of aviation-grade aluminum alloy, precision CNC machined, with sandblasted and anodized surface, for a non-slip and durable experience. (OAG-L and OAG-L-68 come with built-in dual-focuser, for stable guiding performance.)

Note: The ZWO HF (Helical Focuser) is designed exclusively for assisting focus adjustment when connecting ZWO mini series cameras to an OAG for guiding.
