Baader's New 3.5nm Narrowband Enforced H-alpha Filters  These three sizes of 3.5nm Enforced-Narrowband filters upen up the extremely narrow 3.5nm H-alpha world.  This enforced contrast provides more signal of the faintest nebula detail.  Manufacturing such ultra-narrow filters requires extreme coating homogeneity and very high Center Wavelenth Precision, which these filters have been designed for.  The intial production has centered on the most important sizes: 2"/50.8mm Round, and 50x50 Square - other sizes to follow.
