Meade Series 4000 Color Filter Set #1 #07530. Permits observation and photography of planetary surface detail that is often virtually invisible without filtration. Choose the filter or filter set that best meet your needs and see what you have been missing! Use filters individually or stacked to achieve selective filtration of the visual color spectrum.
Manufactured from the finest optical glass, each filter has its color spectrum dyed into the glass instead of being done with inferior color coatings. All filters are anti-reflection coated on both sides of the glass for the highest performance and are threaded for and compatible with all Meade Series 4000 and Series 5000 eyepieces.
Color filters are considered by many to be an essential "must have" for observing and imaging the Moon and planets. The Filter Set #1 includes the following:
- #12 Yellow (74% transmission): Contrasts strongly with blue-colored features on Jupiter and Saturn, while enhancing red and orange features. Useful in increasing the contrast of lunar features.
- #23A Light Red (25% transmission): Strong contrast and enhancement of marginally defined blue-green surface detail. Useful primarily on Jupiter, Saturn, and Mars. Increases contrast between Mercury and bright blue sky during daylight observations or during twilight.
- #58 Green (24% transmission): Belts and structure on Jupiter and Saturn. Strongly increases contrast of Mars' polar ice caps, and increases contrast of difficult atmospheric phenomena on Venus.
- #80A Blue (30% transmission): A popular filter for the study of Jupiter and Saturn. Enhances contrast of rills and festoons in Jupiter's cloud belts, as well as details of the Red Spot. Brings out detail in Saturn's belts and polar phenomena. Very useful as a contrast-enhancing lunar filter.
