Baader Narrowband Enforced 3.5nm H-Alpha Filter 50x50 Square 2459456


Baader Narrowband enforced 3.5nm H-alpha Filter, 50x50 mm Square

These 3.5 nm H-alpha Enforced-Narrowband Filters open up the extremely narrow 3.5nm H-alpha world. 
This enforced contrast results in even fainter stars, providing more signal of faintest nebulae detail. Manufacturing such ultra-narrow filter does require extreme coating homogeneity and very high CWL precision, which these filters are designed for (CWL= Center-wavelength).

These are available in sizes:  2" Mounted (#2459454),  50.4mm round unmounted (#2459455)  and 50x50mm square unmounted (#2459456)
