The ZWO Large Off Axis Guider (OAG-L) gives you the advantage of using an off-axis guider over a small auxiliary guide scope, allowing you to use the same focal length as the imaging telescope. Your primary imaging telescope will have a larger aperture than a small guide scope, pulling in more guide stars and providing better guiding accuracy.

For guiding, the OAG-L can only work with ASI Mini cameras like ASI174MM Mini, ASI290MM Mini and ASI120MM Mini.

Recommended to use with 2” EFW or 7x36mm EFW, and with APS-C cameras (ASI2600) or full-frame cameras (ASI6200/2400). The large clear aperture supports full-frame cameras without vignetting.
