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 12nm bandwidth of light centered on a wavelength of 656nm to pass through; 90 percent transmission at H-alpha line 656nm; 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
2 inch Diagonal Mirror with 99 percent reflection; optics are made with Pyrex glass; Multi layered dielectric coatings that produce 99 percent reflectivity for brighter and harper images
Comes with dielectric coatings for the most light transmission possible; Suitable for refractors included Schmidt-Cassegrains; ACF; EdgeHD and Maksutov-Cassegrains; 2 inch and 1.25 inch reducing sleeve with brass compression ring; non-marring compression safety secures the eyepieces
