Antlia 4.5nm Edge Filters Size:SII 50mm super emission abilityAntlia 4. 5nm EDGE Filters (H alpha, SII, OIII) Overview Antlia 4. 5nm EDGE Filters are engineered to overcome the challenges of conventional narrowband filters, which often experience significant transmission loss due to Central Wavelength (CWL) shifts. With a guaranteed transmission rate of over 90% (T>90%) within a 1nm range of the central bandwidth, Antlia 4. 5nm EDGE Filters deliver outstanding performance for both long focal ratios and fast
