The filter adapter ring that allows you to use the filter with a smaller filter thread size.

2

No need for buying another set of filter drawers, the 2”-1.25”filter adapter ring will help you directly fit the 1.25”filter onto 2” filter drawer or filter wheel.

Supported list:

ZWO 5×2”EFW

ZWO 7×2” EFW

ZWO filter drawer series, including M42 filter drawer and M54 filter drawer

The effect when connecting 2”filter drawer:

连接M54滤镜抽屉（无滤镜）

连接M54滤镜抽屉（有滤镜）

The effect when connecting 2”EFW:

连接2寸滤镜轮（无滤镜）

连接2寸滤镜轮（）有滤镜

We recommend you use ASI533, ASI183, ASI294 and ASI1600 with this filter adapter ring since cameras with bigger sensors may lead to vignetting when matching the 1.25” filters.
