Antlia ALP-T Dualband 5nm HA & OIII Filter - High Speed Version for f/2.2 - f/3.6 Optics - 2" - ALPT-DB-5NM-HAOIII-HS-2 Antlia Dual & Tri-Band Filters ASI2600MC/MM DUO is based onAbout the High Speed Characteristics of this Dual Ha OIII 5nm Filter The Antlia ALP T Dual Band 5nm Highspeed Filters are further optimized to work with very fast imaging systems by shifting the passband and center wavelength slightly. Using these highspeed filters with optical focal ratios between f 2. 2 and f 3. 6 shows more contrast in nebulae imaging compared to the standard version of this filter. For f ratios slower than f 3. 6, the standard ALP
