PLANETVIEW FILTERS [ Individual Colour Filters ]
Veteran astronomers are convinced that planetary observations are almost always dramatically improved by colour filters. Earth’s atmosphere is in constant fluctuation: turbulent air currents blur fine surface detail on solar system objects viewed through a telescope. Faint contrasting area blend together due to “irradiation” - a distortion of the boundaries between light and dark surfaces. Using
planet view filters, the scattering of interfering wavelengths is enormously reduced. With filters the smeared, pale bands of Jupiter resolve into loops and festoons. Delicate markings appear on Saturn’s globe, and the Cassini ring division darkens and solidifies, Mar’s Polar caps stand out like tiny pearls, and the Lunar rills acquire greater depths and contrast. Bad seeing becomes acceptable; good “seeing” becomes superb. For Visual use simply thread these filters into the 1.25” eyepiece barrel of any imported or Super Astro Eyepiece / Plossl Eyepiece. For an ASTRO
EYEPIECE 1.25” OD an extra adaptor is supplied at an extra cost since Astro Eyepiece does not have an inbuilt thread to adopt this new variety of colour filters.

FILTER ADAPTOR only for Astro Eyepiece . . . . Rs . 210.
This FILTER ADAPTER adapts Moon Filters and Planet View Colour Filters which threads into the front barrel of the FILTER ADAPTER. This is to be used in conjunction with Astro Eyepiece 1.25 OD since Astro Eyepiece do not have filter adaptable threads.
NOTE : Never use these Planet view Photo-Visual Filters to observe the Sun. Instant and irreversible
eye damage may otherwise result.
