The Baader Filters H-alpha CMOS f\/2 Highspeed 1.25\u2033 is designed for modern CMOS cameras and high-speed optical systems such as RASA and HyperStar. This filter is precisely matched to the H\u03b1 emission line of 656.3 nm<\/strong> and optimized for an f\/2 light cone so that transmission does not shift with extremely fast optics.<\/p>\n\n\n\n

The multilayer hard coating offers exceptional light transmission (>90%) within a bandwidth of approximately 6.5 nm. As a result, H\u03b1 emissions in nebulae are captured razor-sharp, while light pollution and continuum light are almost completely suppressed.<\/p>\n\n\n\n

Application:<\/strong>
Ideal for emission nebulae such as the Rosette Nebula, Veil Nebula or California Nebula.
Compatible with 1.25\u2033 filter wheels and suitable for CMOS cameras and refractors up to f\/2.<\/p>\n\n\n\n

Specifications:<\/strong>
Filter type: H\u03b1 narrowband (CMOS f\/2 Highspeed)
Central wavelength: 656.3 nm
Bandwidth (FWHM): \u00b16.5 nm
Transmission:>90%
Barrel size: 1.25\u2033
Coating: Hard, anti-reflection
Compatible: f\/2 optics
