                SVBONY 1.25" Astrophotography LRGB Imaging Filter Set Suitable for Deepsky and Planetary CCD Imaging

                Product Description

                ?Description

                The Svbony 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.

                OIII emission overlaps on blue and green
                filters with maximum transmission to allow high efficiency and natural
                color imaging. Gap between green and red filters serves to block out the
                primary Sodium light pollution line at 589nm and improves color balance
                and separation.

                ?Feature:

                • Suitable for deepsky and planetary CCD imaging, work well with debayered monochrome CCD cameras.
                • RGB-imaging allows equal weighting factors for each channel, very important for automated imaging.
                • The ideal raw material for image processing in the sRGB color space is available with LRGB filter set and mono CCD camera.
                • 1.25" astronomy filter with standard M28.5x0.6 male
                  filter thread (no female thread, so it cannot be stacked with other
                  filters).
                • Ultra-thin filter cell to minimize vignetting; clear optical aperture of 26mm.
                • Precision CNC-machined metal filter cell with sand
                  blasted black anodized finish, anti-reflection treatment, and laser
                  engraving.
                • Note: The filters are not designed for sun observation. DO NOT LOOK AT THE SUN WITH FILTER.

                ?Spectral Curve Transmission Characteristics

                • High and precise blocking of offband, 95% transmission at passband.
                • Blocks out infrared wavelengths (700-1100nm) so a separate IR cut-off filter is not required for imaging applications.
                • Both surfaces are fine optically polished, accurate to 1/4 wavelength or better, and parallel to within 30 seconds or arc.
                • 2mm thick optical glass substrate material.
                • Very high surface quality of 60/40 or better (US Military Spec MIL-O-13830).

                ?Optical Coating Specifications

                • Multi-layer anti-reflection coated.
                • Non-cementing optical substrate coating.
                • Electron-beam gun evaporation with Ion-assisted
                  deposition coating technology for durability and resistance to
                  scratching, as well as stability on CWL (central wavelength) so that
                  there is no deviation due to temperature changes during use.
                • Precise and homogeneous coatings ensure high values of desired passband and blocking of unwanted offband.

                ?Package Includes

                • SVBONY 1.25" LRGB Astrophotography Filter Set
                • Silver Cardboard Box
