Optolong Filters LRGB Filter-Set 1,25

The LRGB filter set is essential for capturing colorful images of the night sky using monochrome CCD cameras. This set includes four filters designed to produce a full-color image by combining different spectral channels.

Monochrome CCD cameras offer superior resolution compared to their color counterparts. With the LRGB filter set, the entire chip's potential is utilized, resulting in high-resolution color images.

Here's how each filter contributes to the process:

• Luminance (L) Filter: This filter allows the entire visible light spectrum to pass through while blocking near UV and IR light. It collects all the essential object information, providing the base for the final image.
• RGB Filters: These three filters, representing red, green, and blue, respectively, are responsible for capturing specific color channels. By combining the images from these filters, the full spectrum of colors perceivable by the human eye is reproduced.

During image processing, the four images captured through the LRGB channels are combined to create the final color photograph. Using the Omegon Filter Wheel alongside the LRGB filter set allows for quick and seamless filter changes during astrophotography sessions.

Key Advantages:

• Enables color photography with monochrome CCD cameras
• Utilizes full chip resolution with four external filters
• Features durable, scratch-resistant coatings
• Produces neutral colors ideal for deep sky objects and planets
