Capture the two main emission nebulae bands at the same time, whilst suppressing light pollution, moonlight, and airglow.
More data in less time, opening up your imaging window, even into the summer months when it isn't quite dark yet. Capture twice the Oiii data, whilst obtaining Sii to complement the Altair Ha Oiii DualBand filter.
Extremely steep bandpass yields maximum contrast in extreme light pollution: 4nm FHWM centred on 500.7nm Oiii wavelength, and 4nm FHWM centred on the 671.6nm Sii wavelength.
Halo suppression anti-reflective coating.
Can be used with One Shot Colour (OSC) CMOS or mono astronomical cameras for luminance data.
Includes UVIR blocking for both modified and un-modified DSLR cameras.
The 2" filter has standard M48x0.75mm thread, and fits inside the Altair Magnetic Filter holders, standard 2" filter wheels, plus the Altair Canon / Nikon DSLR lens to astro CMOS adaptors.
The Altair Astro Premium Oiii 6.5nm filter is designed for astro imaging of nebulae with Mono CCD or CMOS cameras, blocking light pollution by cutting out the light pollution wavelengths. The filter blocks UV IR and has an anti-reflection AR coating.
The Altair Astro Premium Sii 6.5nm filter is designed for astro imaging of nebulae with Mono CCD or CMOS cameras, blocking light pollution by cutting out the light pollution wavelengths. The filter blocks UV IR and has an anti-reflection AR coating.
The Altair Astro Premium 7nm Ha filter is designed for astro imaging of nebulae with Mono CCD or CMOS cameras, blocking light pollution by cutting out the light pollution wavelengths.
The Altair Astro Premium Narrowband filter set is designed for astro imaging of nebulae with Mono CCD or CMOS cameras, blocking light pollution by cutting out the light pollution wavelengths.
