Meade Series 4000 Photo-Visual Color Filter #25A Red

7515 - #25A Red (14% transmission): strongly blocks the transmission of blue and blue-green wavelengths, resulting in very sharply defined contrast between blue tinted cloud formations on Jupiter and the lighter-toned features of the disk. Also useful for the delineation of the Martian polar ice caps and maria. Because of its relatively low total light transmission the #25A filter should be used on telescopes of 8" or larger.

Meade Series 4000 Photo-Visual Color Filter #38A Dark Blue

7519 - #38A Dark Blue (17% transmission): Is a popular filter for the study of Jupiter's disk, owing to the filter's strong rejection of orange and red wavelengths. It increases contrast between the reddish belt structures and enhances detail of the Red Spot. Also useful for the study of isolated phenomena, such as dust storms, on Mars, as well as the belt structure of Saturn. Increases contrast of subtle cloud markings on Venus.
