SVBONY SV240 Multi-Narrowband Filter Galaxy & Nebula NIR Near-infrared Light Pollution 2" Mounted for Urban Astrophotography

My problem with this filter is this filter is built slightly smaller than the same svbony UV/IR cut filter 1.25 inch.\nFor me, my uses is different from conventional use. I unscrew the filter, took out the pure glass and put it into a 3D printed adapter for my Nikon apsc dslr camera. It was a bit loose. I got no problem with the same svbony UV/IR cut and IR pass filters 1.25 inch filters. It was tight fit and won't fall off the adapter. \nIf you use it just as it is without taking out the glass, as usual conventional use, i think it is fine.
