Description
Take your astrophotography to the next level with this set of 1.25" Luminance (IR cutoff), Red, Green, and Blue telescope filters. They're designed for creating high-quality composite color astrophotos. 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, and all filters are parfocal to eliminate the need for refocusing between exposure sets. Their anodized aluminum cells thread into the Alstar multiple filter wheels for convenient and most other manufacturer's, 1.25- inch eyepieces.
