Product description
TS Optics 1.25" Filterset - 4 filters for telescopes from 150 mm aperture

Three color and one neutral grey filter. They can be combined with each other.

With this set of four high quality TS filters, one can improve the observation quality on Moon and Planets. Even at double stars, improvements are possible. The filters can be used for both visual observation and photography.

The neutral grey filter reduces e.g. the glare of the moon (if used alone) and can enhance the effect of the other filters if combined with them.

This set is recommended for telescopes from 150mm aperture. All filters are made from optical glass substrate, have a metal mount with threads on both sides.

Our set includes the following filters
  • Dark Yellow #15A
    Similar to yellow, suitable for bigger aperture telescopes. Removes false colour in Fraunhofer refractors.
  • Dark Red #29
    Similar to light red. This filter will make for an extreme contrast. Well suited for Venus by blocking the blue daylight. The sky appears black.
  • Dark Green #58A
    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.
  • ND09 neutral gray
    Neutral density without color effect and 13% transmission. For reducing glare at lunar observations or in combination with a solar filter at solar observations.

  • Plano-parallel glass substrate and anti-reflective coated surfaces
  • Metal cell with M28.5 filter threads on both side, suitable for 1.25" eyepieces and adapters
