The NO.15/25/58/80A Color Filter
Since planetary surface details and atmospheric phenomena reflect sunlight as contrasting colors, you can use color filters to accentuate subtle details on planets, comets, and the Moon by selectively increasing contrast between features and markings of different hues. Simply put: using various color filters makes planetary details easier to see.
Features:
#15 Deep Yellow Planetary Filter: Boosts contrast of lunar features, accentuates red and orange features on Saturn, Jupiter, and Mars, reveals low-contrast cloud detail on Venus.
#25 Red Planetary Filter: Enhances Martian surface details in large telescopes, reveals cloud definition on Venus, accentuates bluish cloud regions on Jupiter and Saturn.
#58 Green Planetary Filter: Enhances contrast of blue and red structures on Jupiter (including Red Spot), melt lines around Martian polar ice caps, accentuates Saturn's cloud belts.
#80A Medium Blue Planetary Filter: Enhances details in Jupiter's belts and Red Spot, high clouds and polar caps on Mars, lunar surface details, Venus cloud features.
Pls note:
The filters of SVBONY are not designed for sun observation. Do not look at the sun with SVBONY filter. You would be blind if you fail to observe the warning

Universal Science:
Waxing Crescent Moon - As the Moon moves around the Earth, we get to see more and more of the illuminated half, and we say the Moon is waxing. At first we get a sliver of it, which grows as days go by. This phase is called the crescent moon. It's very good effectto use the ND4 filter at this time
Last Quarter Moon - Three weeks after new, we again can see half of the illuminated part. This is usually called last quarter. Quarter Moon - A week after the new moon, when the Moon has completed about a quarter of its turn around the Earth, we can see half of the illuminated part; that is, a quarter of the Moon. This is the first quarter phase. It's very good effect to use the ND8 filter In this two time period
Gibbous Moon - From now on, until it becomes new again, the illuminated part of the Moon that we can see decreases, and we say it's waning. The first week after full, it is called waning gibbous. It's very good effect to use the ND16 filter at this time
Full Moon - Two weeks after the new moon, the moon is now halfway through its revolution, and now the illuminated half coincides with the one facing the Earth, so that we can see a full disk: we have a full moon. It's very good effect to use the ND1000 filter at this time

The LRGB Imaging Filter Kit
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.
Features:
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.
