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