0 in stock
50.4 mm x 3 mm Baader H-alpha Narrowband Filter – Precision Grade 6.5 nm FWHM, recommended for optical systems from f/10 to f/3.5 Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™) Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies We explicitly warn against observing the sun with a DeepSky 6.5 nm (equivalent to 65 Ångstroem) H-alpha narrowband filter, specialized solar chromosphere and prominence filters from SolarSpectrum start at 0.8 Ångstroem. Photographic experiments with a camera are theoretically possible, but by no means observe the sun with naked eyes – you endanger your eyesight!
