Robtics Color Filter Set for Planetary Observations - 7 filters 1.25 inch

Robtics Color filter Set including 7 different filters.

The following seven 1.25 inch sized filters are included in this Robtics color filter set:

• Violet - The violet filter totally blocks red, yellow and green light, which is useful when observing the polar regions on Mars. With larger telescopes (>12''), it also allows to distinguish some structures in Venus's atmosphere.
• Blue - The light blue filter is suitable for Moon, Mars, Jupiter and Saturnus observation. It improves contrast on faint areas without affecting the planet's brightness, which is why this filter is often used in combination with others.
• Green - The light green filter is ideal for observing the ice caps on Mars and the yellowish sand storms on the Martian surface. It also improves the contrast of reddish and bluish structures in Jupiter's atmosphere.
• Yellow - The yellow filter improves contrast on Moon craters; on Mars, channels and polar caps become more apparent. On Jupiter and Saturn, contrast is enhanced on the bluish ammonia cloud belts.
• Orange - The orange filter blocks blue and green wavelengths, thus enhancing details in Saturn's and Jupiter's cloud belts. On Mars it sharpens boundaries between orange and greenish areas.
• Red - The red filter blocks blue and green light nearly in total, which means you get a very strong contrast, for instance, between bluish toned structures and the brighter details on Jupiter's and Saturn's clouded surface. However, this filter is mainly used to observe Martian polar caps.
• Light Pollution Filter - Reduces general light pollution for deepsky observations.
