Take your astrophotography to the next level with this set of 1.25" Luminance (IR cutoff), Red, Green, /*C*and*C*/ Blue telescope filters. They're designed for creating high-quality composite color astrophotos with Orion monochrome imaging cameras /*C*or*C*/ similar monochrome cameras. Combining separate images taken through these four filters with a monochrome CCD provides a higher-resolution final image than an image from a comparably sized color CCD. Our LRGB set features dichroic glass filters designed for maximum transmission. The color filters have an IR-blocking coating, /*C*and*C*/ all filters are parfocal to eliminate the need for refocusing /*C*between*C*/ exposure sets. Their anodized aluminum cells thread into the Orion multiple /*C*and*C*/ motorized filter wheels for convenient filter selection. Foam-lined telescope filter case included.
