Astrophotography under a light-polluted night sky can be difficult; the solution is an H-alpha filter; the Astromania H-alpha cut-off filter works to filter out a large part of this light pollution
Allowing 12 nm bandwidth of light centered on a wavelength of 656 nm 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
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
ADC unit is special corrector designed for planetary observers and photographers; observe planets not only high in sky but even rise and set; with high brilliance and colour and without chromatic aberration; make more flexible in choice of observing time
Ultra-low profile - also suitable for visual observing and bino-viewers; ring scale for adjusting dispersion correction; corrects atmospheric dispersion - less colour fringing; sharper planetary photos and more detail
