ZWO H-ALPHA 7nm NARROWBAND FILTER Size:1.25" Fully functional astrophotography software toThe ZWO 7nm H alpha narrowband filter enhances the contrast of emission and planetary nebulae. These peculiar nebulae emit light only in specific wavelengths (H; OIII; SII) and the narrowband filters have the property to reject all light outside these bands. The passing band or "window" of these filters is 7nm wide. Considering that the visible light spectrum is between 380nm and 740nm, a 7nm filter would block 98% of the unwanted light. As a result,
