- Allowing 12 nm bandwidth of light centered on a wavelength of 656nm to pass through; 90 percent transmission at H-alpha line 656 nm; that means the filter also blocks the infamous stray light and light from mercury and sodium vapour lamps
- Young stars embedded in the bright red of a nebula - an H-alpha filter is the expert if you want to capture hydrogen nebulae in all their glory
- The Astromania H-aplha cut-off filter enhances the contrast between object and sky; allowing you to take good quality images even under urban skies
