Orion LRGB Astrophotography Filter

Yes, this LRGB filter set is specifically designed for monochrome imaging cameras. It works by capturing separate exposures through each color channel, which you then combine in post-processing to create a full-color image.

The Luminance filter captures the full spectrum of light, which helps you gather detailed structural data and boost contrast in your images. It is essential for eliminating atmospheric haze and sharpening the final result before you layer in the color data.

These filters are designed for standard 2-inch filter wheels or threaded nosepieces. They are particularly well-suited for larger CCD sensors, as the 2-inch size helps prevent vignetting that can occur with smaller 1.25-inch filters on wide-format sensors.

While these filters are primarily for color synthesis, they do block UV and IR light, which helps reduce unwanted halos and improves overall image sharpness. However, they are not specialized light pollution filters, so you may still need a dedicated narrowband filter if you are shooting from a heavily light-polluted area.

These filters are designed to be parfocal, meaning they share the same optical thickness. This allows you to switch between the Red, Green, Blue, and Luminance filters without needing to refocus your telescope between each exposure.
