Astronomik SII 6nm CCD 50mm

Emission line filter SII-CCD 6nm

Our 10 Year Warranty

Our 50mm filters fit perfectly in all 50mm 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.
