Meade Series 4000 Color Filter Set #1 - 1.25" Round Mounted


The Meade Series 4000 Color Filter Set #1 is an essential tool for lunar and planetary observation because they provide views and imaging of surface detail that is often virtually invisible without filtration. Experience stunning images with reduced irradiation and improved high-contrast!

Take advantage of ideal atmospheric conditions and experience dramatic observation of planets. See small craterlets on the floor of Clavius on the Moon, See more than two whirls, festoons, and loops in Jupiter's North equatorial belt, see the inner ring of Saturn. 

Features of the Meade Series 4000 Color Filter Set #1 

  • Large clear aperture of 26 mm, manufactured from the purest crown optical glass, dyed-in-the-mass (not color coated).
  • Anti-reflection coated glass on both sides of each filter and is mounted in a machined aluminum cell with the Wratten No. of the filter marked on the side of the cell.
  • Achieve selective filtration of the visual color spectrum by stacking filters. 
  • Fits Meade barrels of 1.25-inch eyepieces and into the barrels of virtually all other 1.25-inch eyepiece brands as well.
  • Compatible with the eyepiece-holders of a Schmidt-Cassegrain telescope or Meade ED Apochromatic Refractor for Tele-Extender eyepiece-projection photography of the Moon and planets. The filters also thread into the barrels of the Meade Camera Adapter (1.25 inches) and Variable-Projection Camera Adapter.
  • Secure long-term storage with each Series 4000 filter packed in a foam-fitted plastic case.

Meade Series 4000 Filter Set #1 includes

#12 Yellow (74% transmission)

Contrasts strongly with blue-colored features on Jupiter and Saturn while enhancing red and orange features. Lightens red-orange features on Mars, while reducing or blocking the transmission, and thereby increasing the contrast, of blue-green areas. Useful in increasing the contrast of lunar features in telescopes 6-inch aperture and larger.

#23A Light Red (25% transmission)

On telescopes with a 6-inch aperture and larger, the #23A does approximately the same functions as the #21 filter, but with stronger 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)

Use on telescopes 8-inch aperture and larger to reject blue- and red-toned structures on the surface of Jupiter and thereby increase their contrast relative to lighter parts of the disc. Also, use for the enhancement of Saturn's cloud belts and polar regions. It also strongly increases contrast of Mars polar ice caps and increases the contrast of atmospheric phenomena on Venus.

#80A Blue (30% transmission)

A popular filter for the study of Jupiter and Saturn. Enhances contrast of rilles 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.

Great Service

I haven't used the filters and the Barlow on my telescope yet, so this review is solely about the service. First a few words about ratings. Three stars means you met my expectations. Anything less, you should worry about your service, more that three, your doing fine but have room for improvement until you get to the five star level. I really don't know what "Five Star" level service is. I'll bet it's very RARE!! I was very satisfied with OPT's service and with the quick arrival of my order. It was well packaged and arrived as predicted. I do intend to do further business with OPT in the future. Thanks!!
