Askar Colour Magic Narrowband Filters

Askar Colour Magic filters are 2" narrowband and dual-band filters for deep-sky imaging under light-polluted skies. Single-band 3nm H-alpha, OIII and SII filters serve monochrome cameras, while the dual-band pairs isolate Ha/OIII and SII/OIII so a color camera can capture both halves of a bicolor or SHO-style palette.

The dual-band filters come in three families: the C series, the 6nm Super D series and the 3nm Ultra E series, each also sold as a two-filter package.
