TS Optics 1.25" Filterset - 4 filters for telescopes from 80 - 140 mm apertureThree 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 80mm to 140mm aperture. All filters are made from
optical glass substrate, have a metal mount with threads on both sides.
Our set includes the following filters- Yellow #12
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 - Light Red #23A
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. - Blue #80A
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. - ND06 neutral gray
Neutral
density without color effect and 25% transmission. For reducing glare
at lunar observations or in combination with a solar filter at solar
observations.
