Product Description This complete Olivon filter- and ocular set fits on refractor- and reflector telescopes with a 2" (50.8mm) ocular holder. The whole comes in a luxurious lined case. With the purchase of this set, you enrich your observations with different filters, or you can increase / decrease the magnification with one of the three oculars supplied.Specific characteristics oculars:<br /> - Eight element design<br /> - 70° angle of view<br /> - Foldable eye pieces<br /> - Full high quality multi-coating<br /> - Maximises the magnification of your telescope (magnification = focal length telescope : focal length ocular)<br /> - Suitable for telescopes with a 2" ocular sizeSpecific characteristics Barlow lens:<br /> - Increases the magnification by 2x<br /> - Operates in combination with 2" oculars<br /> - Fits on telescopes with 2" ocular sizeSpecific characteristics filters:<br /> Polarisation filter (#3) 2" <br /> - Increases contrast of the surfaces of the moon with various luminosity<br /> - Increases contrast between surfaces with different planetary transmissions<br /> - Turns blue skies even deeper blue<br /> - Eliminates surface reflections<br /> <br /> Yellow Filter #12 2" (74% VLT*)<br /> - Increases the contrast between lunarscape characteristics in various light conditions<br /> - For observing the contrast of the thick Venus cloud under good light conditions<br /> - To increase the contrast of the polar caps, frozen areas and low clouds on Mars<br /> - Darkens the atmospheric currents of Jupiter<br /> <br /> Orange filter #21 2" (46% VLT*)<br /> - Increase contrast between lunarscape characteristics<br /> - Mercury, for decreasing the luminosity of the observation when observing by daylight<br /> - Venus, for decreasing the luminosity of the observation when observing by daylight<br /> - To increase the contrast of the polar caps, frozen areas and low clouds on Mars<br /> - For a better observation of the structure of Jupiter's band<br /> - For a better observation of the structure of the atmospheric bands of Saturn<br /> <br /> Light Red filter #23A 2" (25% VLT*)<br /> - For better observing the blue tinted cloud formations of Jupiter<br /> - Improving the observations when Mercury is in the twilight zone (when the planet is close to the horizon)<br /> - Venus, for decreasing the luminosity of the observation when observing by daylight<br /> - For improving the contrast of the polar caps, frozen areas and low clouds on Mars<br /> <br /> Green filter #56 2" (53% VLT*)<br /> - Increases the contrast between lunarscape characteristics under various light conditions<br /> - For observing the pattern of the clouds of Venus<br /> - Mars, to increase the contrast of the polar caps and observe the frost<br /> - Increases the visibility of the great red spot of Jupiter<br /> - For a better observation of the white elements in the atmosphere of Saturn<br /> <br /> Light blue filter #82A 2" (73% VLT*)<br /> - Increase the contrast between lunarscape characteristics<br /> - Improves the boundaries between the red belts and the adjoining bright zones of Jupiter<br /> - Usable during violet clearing and when studying the surface of the polar caps of Mars<br /> - Improves the low contrast details of cloud formations of Saturn<br /> <br /> Moon filter crystal view 2" :<br /> - Increases the contrast of the lunar surface, while the surplus light pollution is stopped* VLT = Visual Light Transmission. The lower the percentage, the less light is let through. Filters with a VLT of less than 40%, are only recommended for telescopes with a lens diameter of 6" or larger.
