Description

Optolong LRGB-CCD Filter Set

Premium Quality Optolong LRGB-CCD Filter Set designed for CCD cameras and astro modified dSLR cameras to take amazing images of deepsky objects. Compatible with 1.25" eyepieces and other accessories.

This Optolong LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into its components: red, green, blue and luminance. The OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. A gap in the transmission's spectrum of green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance as well as separation.

Main Use and Performance

It works well with debayered monochrome CCD cameras. Suitable for deepsky and planetary CCD imaging. RGB-imaging allows equally weighted factors for each channel, that is very important for automated imaging. An ideal raw material for image processing in the sRGB color space can be achieved with this LRGB filter set and a monochrome CCD camera.

WARNING:

Optolong filters are not designed for solar observation. DO NOT LOOK AT THE SUN WITH ANY OPTOLONG FILTER as permanent eye damage will be the result.
