Description Technical Specs

The Wideband StarGuy H Alpha, FWHM 12nm, filter is a deep red long pass filter that enhances the contrast of nebulae emissions and reduces the effects of light pollution by only passing the hydrogen alpha light. The H Alpha filter is designed to transmit a wide band of Hydrogen allowing more light through than the narrowband version for shorter exposures. Ideal for emission nebulae such as the Horsehead and North American. The filter eliminates halo effects with double sided polishing technique and coatings. 100% tested and inspected by MrStarGuy.
