1.25" TS Optics Colour Filter - Yellow / Green #11

TS Optics colour filters offer an improved contrast when viewing the moon and the planets. Each filter works out specific details by permitting only specific parts of the visual spectrum. As a resul the contrast of these details is boosted for better visibility.

Quality Features of the TS Optics Colour Filters:

- the filter housing is made of metal and as thin as possible to avoid vignetting.
- the glass used in our filters is very homogenous and parallel
- we promise a very good image quality!
- filter threads on both sides allow you to combine different filters. For example, a blue filter and a yellow filter combined resemble a green filter.

Combine several colour filters to get even further colour shades

Each of the 14 different 1.25" colour filters has a different effect on the image. As a result different filters are used for viewing different details of a planet. By combining two filters you can get additional colour shades. For example, a blue filter and a yellow filter combined resemble a green filter with a different shade than the normal green filter.

Below is a list of the various available filters with examples for their use. Under "Recommended Accessories" you can find the other filters from our product range.

Colour	Recommended minimum aperture	Recommended for use on...
Light Yellow #8	50mm Aperture	Moon, Mars, comets - you can reduce false colour in Fraunhofer refractors. A nice universal contrast filter, even for small aperture telescopes.
Yellow / Green #11	60mm Aperture	Well suited for observations of Jupiter and Saturn. Reveals atmospheric structures even in small aperture telescopes.
Yellow #12	80mm Aperture	Enhances contrast on the moon, reveals surface details and clouds on Mars, enhances cloud structures on Jupiter (e.g. the Great Red Spot). Can be used in double star observations with refractors - reduces false colour in Fraunhofer refractors.
Dark Yellow #15A	120mm Aperture	Similar to yellow, suitable for bigger aperture telescopes. Removes false colour in Fraunhofer refractors.
Orange #21	80mm Aperture	Enhances contrast in daytime and twilight observations (Venus, Mercury) by suppressing the blue light. Reveals details on Mars (in larger aperture telescopes). Further details in Jupiter's and Saturn's atmosphere are revealed. You may try spotting atmospheric structures on Uranus with large aperture telescopes..
Light Red #23A	60mm Aperture	For very high contrast on the Moon - suitable for small aperture telescopes. This filter is used when observing the polar ice caps on Mars (100mm aperture and larger). Well suited for Venus by blocking the blue daylight. The sky appears black.
Red #25	80mm Aperture	Similar to light red, suitable for telescopes of 100mm aperture and larger.
Dark Red #29	120mm Aperture	Similar to light red, suitable for telescopes of 150mm aperture and larger. This filter will make for an extreme contrast.
Light Blue #82A	50mm Aperture	An important universal contrast filter for all telescopes, similar to light yellow. It brings along a gain in contrast on many objects within our solar system.
Blue #80A	70mm Aperture	General contrast gain on the moon, off its terminator. Enhances contrast in Jupiter's and Saturn's cloud bands. Enhances surface details on Mars. In large aperture telescopes you may see cloud details on Venus. Good comet filter - boosts contrast in the comet's tail.
Dark Blue #38A	100mm Aperture	Similar to blue, suited for telescopes of 150mm aperture or larger.
Violet #47	120mm Aperture	Well-suited for observing Venus in telescopes of 150mm aperture or larger. It makes visible the dark clouds in Venus' atmosphere. Boosts structures in Saturn's rings. You may also use this filter on Mercury under good seeing conditions in large telescopes.
Green #56	60mm Aperture	An important universal contrast filter. Drastically boosts contrast on the Moon - better contrast even far off the terminator - suitable for low magnifications. This filter is especially effective on Jupiter, revealing the famous Great Red Spot and other reddish details in the Jovian atmosphere. White spots in Saturn's atmosphere are enhanced in telescopes of 200mm aperture or larger.
Dark Green #58	120mm Aperture	Similar to green, but suitable for telescopes of 150mm aperture or larger
