Skywatcher are just added another new product to the range of already bulging accessory list. The Skywatcher Lunar / Planetary filter set is the latest addition allowing you to get the best possible view from your telescope. Supplied in 31.7mm fitting the filters simply screw onto the rear of most eyepiece on the market and will improve on contrast and details on the major planets. The colours included and what they give you are as detailed below :
P01 Green Filter(24% transmission): Use on telescopes 8″ aperture and larger to reject blue- and red-toned structures on the surface of Jupiter and thereby increase their contrast relative to lighter parts of the disc. Also use for the enhancement of Saturn’s cloud belts and polar regions. Strongly increases contrast of Mars’ polar ice caps, and increases contrast of atmospheric phenomena on Venus. #12 Yellow (74% transmission): Contrasts strongly with blue-colored features on Jupiter and Saturn, while enhancing red and orange features. Lightens red-orange features on Mars, while reducing or blocking the transmission, and thereby increasing the contrast, of blue-green areas. Useful in increasing the contrast of lunar features in telescopes 6″ aperture and larger.
#25A Red (14% transmission): The #25A filter strongly blocks the transmission of blue and blue-green wavelengths, resulting in very sharply defined contrast between, for example, blue-tinted cloud formations on Jupiter and the lighter-toned features of the disc. Also useful for the delineation of the Martian polar ice caps and maria.
ND 96 Moon Filter(0.9 density; 13% transmission): The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4″ and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness.
