Olivon SWA Eyepieces In Case Set 2

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: - Eight element design - 70° angle of view - Foldable eye pieces - Full high quality multi-coating - Maximises the magnification of your telescope (magnification = focal length telescope : focal length ocular) - Suitable for telescopes with a 2" ocular size Specific characteristics Barlow lens: - Increases the magnification by 2x - Operates in combination with 2" oculars - Fits on telescopes with 2" ocular size Specific characteristics filters: Polarisation filter (#3) 2" - Increases contrast of the surfaces of the moon with various luminosity - Increases contrast between surfaces with different planetary transmissions - Turns blue skies even deeper blue - Eliminates surface reflections Yellow Filter #12 2" (74% VLT*) - Increases the contrast between lunarscape characteristics in various light conditions - For observing the contrast of the thick Venus cloud under good light conditions - To increase the contrast of the polar caps, frozen areas and low clouds on Mars - Darkens the atmospheric currents of Jupiter Orange filter #21 2"(46% VLT*) - Increase contrast between lunarscape characteristics - Mercury, for decreasing the luminosity of the observation when observing by daylight - Venus, for decreasing the luminosity of the observation when observing by daylight - To increase the contrast of the polar caps, frozen areas and low clouds on Mars - For a better observation of the structure of Jupiter's band - For a better observation of the structure of the atmospheric bands of Saturn Light Red filter #23A 2" (25% VLT*) - For better observing the blue tinted cloud formations of Jupiter - Improving the observations when Mercury is in the twilight zone (when the planet is close to the horizon) - Venus, for decreasing the luminosity of the observation when observing by daylight - For improving the contrast of the polar caps, frozen areas and low clouds on Mars Green filter #56 2" (53% VLT*) - Increases the contrast between lunarscape characteristics under various light conditions - For observing the pattern of the clouds of Venus - Mars, to increase the contrast of the polar caps and observe the frost - Increases the visibility of the great red spot of Jupiter - For a better observation of the white elements in the atmosphere of Saturn Light blue filter #82A 2" (73% VLT*) - Increase the contrast between lunarscape characteristics - Improves the boundaries between the red belts and the adjoining bright zones of Jupiter - Usable during violet clearing and when studying the surface of the polar caps of Mars - Improves the low contrast details of cloud formations of Saturn Moon filter crystal view 2": - 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.
