Optolong Filters LRGB filter set 31mm (unmounted) (82629)

The LRGB filter set is specifically designed for astrophotography with monochrome CCD cameras, allowing you to capture high-resolution color images of the night sky. Unlike color CCD cameras, which use built-in color filters that reduce resolution, a monochrome camera paired with LRGB filters utilizes the full sensor for each exposure. This results in brighter, sharper images of deep sky objects.

The set includes four filters: Luminance (L), Red (R), Green (G), and Blue (B). The luminance filter transmits the entire visible spectrum while blocking near-UV and IR light, capturing all essential object details. The RGB filters isolate the primary colors-red, green, and blue-which are then combined with the luminance data during image processing to create a full-color photograph. This method mimics how our eyes perceive color, using the combination of primary colors.

For convenience, a filter wheel can be used with the LRGB set to quickly switch between filters during imaging sessions.

Key advantages:

• Enables color astrophotography with monochrome CCD cameras

• Maintains full sensor resolution using four separate filters

• Durable, scratch-resistant coatings

• Produces neutral, accurate colors for deep sky objects and planets
