Meade Series 4000 Photo-Visual Color Filters Product Info

Meade Series 4000 Photo-Visual Telescope Color Filters are an essential tool of the lunar and planetary imageobserver, for filters permit the observation and photography of surface detail that is often virtually invisible without filtration. For visual applications Meade Color Filters thread into the barrels of all Meade 1.25" eyepieces, and into the barrels of virtually all other brands telescope eyepieces of 1.25 inch barrle diameter. The eyepiece with filter can be placed in the eyepiece-holder of a Schmidt-Cassegrain telescope or Meade ED Apochromatic Refractor for Tele-Extender eyepiece-projection photography of the Moon and planets. The Meade Telescope Filters also thread into the barrels of the Meade Camera Adapter (1.25") and Meade Variable-Projection Camera Adapter. Each Meade Series 4000 Color Filter is packed in a foam-fitted plastic case for secure long-term storage.

Meade Filters solve, or greatly reduce the effects of, two basic observing problems:

  • Irradiation is the fuzzying of a boundary between lighter and darker areas of the Moon or a planetary surface and can be caused either by the effects of highly contrasting light impacting the human eye or by the motion of the Earth's atmosphere, through which the observation is being made.
  • Contrast is the separation of adjacent surface regions according to their color; for example, a light green area on Mars can become mixed in the eye with an adjacent light yellow area, to the effect that the combined area appears yellow-green, unseparated into its component regions.

Meade Series 4000 Telescope Color Filters:

  • Large 26mm in clear aperture
  • Manufactured from the purest crown optical glass
  • Dyed-in-the-mass (not "color coated")
  • Each filter glass is anti-reflection coated on both sides

    and is mounted in a machined aluminum cell with the Wratten No. of the filter marked on the side of the cell.

  • Filters may be piggybacked, or stacked, to achieve selective filtration of the visual color spectrum.

Recommended Meade Series 4000 Filter Applications:

# 21 Orange 07510 (46% transmission):

Reduces or blocks transmission of blue-green wavelengths. Use on Jupiter and Saturn to enhance detail in the belts and polar regions. Sharpens boundaries between yelloworange areas and blue-green regions on Mars, resulting in a darkening of edge-detail in the maria.

# 38-A Dark Blue 07519 (17% transmission):

A popular filter for the study of Jupiter's disc, owing to the filter's strong rejection of orange and red wavelengths. 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.
