Celestron LRGB Imaging Filter Set # 95517

Take color images of the night sky with your Skyris monochrome CCD camera, a simple filter wheel, and this four-piece LRGB filter set! These imaging filters were designed in Celestron's facility in California with a spectrum bandpass that produced optimum color balance and sharpness.

Each 1.25" mounted filter has a clear aperture of 26 mm, and is layered with dichroic coatings that allow transmission of more than 92% of the visual spectrum (420 nm-680 nm) while blocking infrared (IR) transmissions that would cause slightly out-of-focus images were they left unblocked. Anti-reflection coatings are also applied in multiple layers to further increase contrast and light throughput, and to protect the filter from the effects of daily use.

The Celestron LRGB Filter Set includes a red (R), green (G), blue (B), and luminance (L) filter. Since they are mounted in a standard 1.25" cell, these filters can be used with a wide variety of cameras, including the Celestron Skyris and The Imaging Source astronomy cameras. Please note that these filters are not intended for visual use.
