Manufacturers Description
The ZWO Off-Axis Guider - Large is an extra wide off-axis guider built specifically for long exposure astrophotography through a long focal length telescope, such as a Schmidt Cassegrain, using a APS-C and full-frame CMOS camas such as the ASI6200, the ASI2400 and the ASI2600 series.
Compared to the M68 and standard OAG, the ZWO Off-Axis Guider - Large has a significantly wider field of view due to its prism size of 12x12mm and can adapt straight onto telescopes with M48 thread using the included M48 sensor tilt plate.
For off-axis guiding, please note that this OAG is only compatible with the ZWO ASI Mini Astronomy Cameras: ASI120MM Mini, ASI174MM Mini and ASI290MM Mini.
