Meade Series 4000 Color Filters permit 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.
The Lunar and Planetary Filter Set includes the following filters:
- #25A Red (14% Transmission) - for sharp contrast in Jupiter's cloud belts, helps define polar caps and maria on Mars. Best for larger telescopes due to restricted transmission.
- #12 Yellow (74% Transmission) - this filter adds contrast to blues, enhances reds and yellows on Jupiter and Saturn, and increases contrast on Mars and on the Moon.
- #80A Blue (30% Transmission) - this is a popular filter for enhancing spiral features in Jupiter's cloud belt including the Red Spot and adding contrast to Saturn and the Moon.
- Moon Filter ND96 (13% transmission) - reduces glare when observing the Moon.
Color filters are considered by many to be an essential "must have" for observing and imaging the Moon and planets.
