• 3.5 nm FWHM (to harmonize the exposure time with O-III / S-II), recommended for optical systems from > f/3.4
• For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail – indispensable under Bortle 9/8/7/(6) skies
• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)

We explicitly warn against observing the sun with a DeepSky 3.5 nm (equivalent to 35 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!
