LRGB 2-inch dielectric filters with clear focus filter for colour imaging
ProStar LRGB set of high transmission 2 inch tri-colour parfocal imaging filters with clear focus filter optimized CCD astrophotography.
For colour imaging with a black and white (monochrome) camera, these filters are much faster than standard dye colour filters. This is especially important when it comes to small aperture telescopes or where a deep sky object is faint (particularly at green or blue wavelengths).
Used with your favourite IR cut filter, the ProStar LRGB filter set splits the spectrum into its Red, Green and Blue components so that colour separation can be achieved with pure Black and White CCD sensors. The separation corresponds to the colour sensitivity of the human eye.
This filter set will ensure you achieve the highest light transmission LRGB images even with small aperture scopes.
All filters have hardened anti-reflection layering
