ZWO Off-Axis-Guider OAG-L

ZWO Off-Axis-Guider OAG-L is the ultimate guiding solution for astrophotographers working with full-frame cameras and long focal lengths. The large 12×12 mm prism allows you to track guide stars that are in the exact field of view of your main camera - resulting in accurate tracking without field rotation or differential errors.

Instead of mounting a separate guidescope, this off-axis guide uses a reflection prism that diverts some of the light to a ZWO Mini guide camera (such as the ASI290MM Mini or ASI174MM Mini). This makes your setup more compact, lighter and more sensitive to small tracking errors.

The OAG-L is optimized for use with the ZWO EFW filter wheel and full-frame ASI cameras, with an optical mount of exactly 55 mm (OAG + EFW + cooled camera). The included tilt adapter (M48) allows you to precisely align the angle of view with your sensor for perfectly flat astrophotos.

✓ Large prism of 12×12 mm - ideal for full-frame guiding
✓ Perfect distance composition - 55 mm with EFW and cooled ASI
✓ Compatible only with ZWO Mini cameras (including ASI174MM Mini).
✓ M48 tilt adapter included - for easy sensor alignment
✓ Compact, light and stable - no more need for a separate guidescope
