Product information
- Baader H-alpha Ultra-Narrowband Filter Premium Grade
- 3.5 nm FWHM (to harmonise the exposure time with O-III / S-II), recommended for optical systems from f/10 to f/3.5
- For highest contrast even at strongest light pollution, minimises star size, emphasises finest nebula detail indispensable under Bortle 9/8/7/(6) skies
- 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 black frontside outer rim
- Optimised for modern CMOS cameras, but 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!
