Our 36mm filters fit perfectly in all 36mm filter wheels of the brands ZWO, QHY, QSI, Starlight Xpress, SBIG, Moravian and Atik. The design with protective ring and blackened filter edges prevents stray light, the filters are mechanically protected and easier to handle.

The orientation of the filter in the filter wheel does not matter. It does not change the optical performance.
