Baader's new 3.5nm Narrowband Enforced H-alpha filter opens 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.
Manufacturer part # # FHALNU-RD36 or 2459453
WARNING: This filter is not designed for solar observation. NEVER use these filters for observing or imaging the Sun, or permanent eye and equipment damage will result.
