This filter was developed to suppress light pollution for colour and monochrome cameras and offers more balanced RGB colours.

• ltair TRI-RGB is great for broadband objects such as mixed emission / reflection nebulae, comets, dust clouds and galaxies, but it also allows the major emission nebulae lines through. It covers both broadband AND narrowband targets.
• TRI-RGB complements the Altair TriBand and DualBand filters by adding star colours.
• TRI-RGB and works with fast or slow focal ratio telescopes and camera lenses. 
• TRI-RGB is not only for light pollution control. It works very well under dark skies too by enhancing colour purity, airglow and reducing channel crossover in colour CMOS and DSLR cameras.
• Although primarily intended for colour cameras, TRI-RGB can be used for a cleaner luminance channel with a mono camera. 
• High transmission peaks with steep sides enhance contrast, together with almost total suppression of unwanted light, at OD4/5 (0.01%~0.001%) over the majority of unwanted visual wavelengths.

Altair DualBand 6nm ULTRA Filter Features:

• Capture two main emission nebulae bands at the same time, per filter, whilst suppressing light pollution, moonlight, and airglow.
• Acquire more data in less time, opening up your imaging window, even into the summer months when it isn't quite dark.
• If you have the 6nm Sii Oiii Ultra filter and the Ha Oiii filter combo, you can capture twice the Oiii data in each imaging session and combine them for true SHO Hubble style imaging with a colour camera!
• Extremely steep bandpass yields maximum contrast in extreme light pollution: 6nm FHWM centred on 500.7nm Oiii wavelength, 5.5nm FHWM centred on the Sii and Ha wavelengths.
• 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, plus an anti-reflection coating for the ultimate in contrast.
• Best performance at focal ratios at F4.8 or slower, however can be used as fast as F3.6, with minimal contrast impact (conservative estimate - faster may be possible). Like any dichroic filter, contrast increases as focal ratio number increases. More info about light pollution filter performance and focal ratio here.
• Available in 1.25" or 2" standard astronomy filter sizes. The filters have standard Astronomy compatible filter threads, and fit inside the Altair Magnetic Filter holders (with appropriate slider), and standard astronomy filter wheels. Choose the 2" version for use with the Altair Canon / Nikon DSLR lens to astro CMOS adaptors. For Hypercam 183C and 533C or 533M, 585C and smaller sensors choose the 1.25" filter. For larger sensors choose the 2" version.
