TS Optics 1.25" filterset - 6 filters for smaller telescopes up to 130mm apertureFive color filters and one neutral density filter for viewing planets and moon
With this set of six high-quality TS filters, your lunar and planetary observations benefit significantly. Even for double stars, colour filters can be used. This set contains the following filters
- light red
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. Reduces seeing influence with monochrome CCD photography.
- light yellow
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, because it reduces false colour in Fraunhofer refractors.
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.
- light blue
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, because it boosts contrast in the comet's tail.
- yellow - green
For applications where the light yellow filter is too weak and the red filter too strong. 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. It also reduces the secondary spectrum of achromatic refractors.
- neutral Density ND06
Neutral grey filter with approx. 25% transmission. Grey filters can be used for planet observing, solar observing (only in combination with a true solar filter!) and for nature observing. The function is similar to regular sunglasses: the image brightness is reduced, meaning less strain for your eyes. The filter can be used visually and photographically. A ND filter is also helpful for observing binary stars by reducing the glare of the brighter component.
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, polished, and parallel
- anti reflective coating
- very good image quality!
- filter threads on both sides allow you to combine different filters
- 5 colour filters each in a plastic storage case
- 1 neutral density filter in a plastic storage case
