Celestron Moon Filter 1.25 Feature

  • Celestron Moon Filter, 1-1/4'' : 94119-A
Celestron's Moon Filters are economical eyepiece filters for reducing the brightness of the moon and improving contrast, so greater detail can be observed on the lunar surface. The clear aperture is 21mm for the 1¼" filter. Transmission is about 18%.1¼" Moon Filter [94119-A]Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue. Celestron's filters are made of high quality, solid plane parallel glass with excellent homogeneity. They're anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit Celestron's, and most other manufacturer's, 1¼" eyepieces, and offer a full 26mm clear aperture. Celestron filters are mounted in black anodized aluminum cells with the Kodak Wratten Series Number individually engraved, and come with a plastic case for safe storage. The cells of each filter are double-threaded, so they can be stacked (piggybacked) in various combinations. This allows you to create different color combinations and transmission characteristics, or to have the same color characteristic, but with a lower transmission. When stacking color filters, the effective transmission of the combination you create is equal to the product of the spectral transmission of each of the filters used.The effectiveness of the filters depends on

1.25" Orion 13% Transmission Moon Filter

1.25" Orion 13% Transmission Moon Filter Review


See more picture


1.25" Orion 13% Transmission Moon Filter Feature

  • The Orion 1.25" 13% Transmission Moon Filter reduces the glare so you can see more lunar detail and surface features with your telescope
  • Threads directly into the 1.25" barrel of your telescope eyepiece
  • Especially useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming
  • Telescope eyepiece filter transmits only 13% of the incoming light, boosting contrast and ability to discren detail on the Moon
  • Perfectly neutral color will not alter the natural color of the Moon
The Moon's disk, even at partial phases, is intensely bright with reflected sunlight. The glare washes out most of the craters, rilles, and other surface details from view. Our 1.25" Orion 13% Transmission Moon Filter reduces the glare, allowing transmission of only 13% of the reflected light. Not only will you see more surface features, but you can study them in greater comfort. The filter reduces irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator. The Orion Moon Filter is especially useful to owners of large-aperture scopes, in which the Moon's brightness can be overwhelming. It uniformly reduces light over the entire visible spectrum. Screws into threaded eyepiece barrel.

Celestron UHC/LPR Night Lighting Pollution Reducer Filter for Telescopes 1.25 inch Thread (1-1/4)

Celestron UHC/LPR Night Lighting Pollution Reducer Filter for Telescopes 1.25 inch Thread (1-1/4) Review

Celestron UHC/LPR Night Lighting Pollution Reducer Filter for Telescopes 1.25 inch Thread (1-1/4) Feature

  • The multi-layer dielectric coatings are plasma assisted and Ionbeam hardened using the latest technology for durability and resistance to scratching.
  • Improved transmission translates to maximum image brightness and contrast. Users of smaller, 4"-11" telescopes will especially appreciate the high efficiency, and larger scope users will love the rich star fields and detailed subtle nebular shadings that are left intact.
  • The high transmission, sharp cutoffs, and more moderate 60nm passband of the UHC/LPR filter retains a more natural view, yet significantly boosts overall contrast. Imagers will appreciate the broader bandpass and inclusion of an extremely efficient H-Alpha passband (656nm)
Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). The new ultra high contrast (UHC) LPR filter has improved contrast over the typical broadband filters. Sky background is darker, and contrast of emission nebulae are noticeably improved. The advanced technology coatings enable the filter to achieve an outstanding transmission of over 97% across the entire bandpass, with total blockage of prominent light pollution lines. The perfect filter for viewing nebula from light polluted skies, or for boosting the contrast of nebula from dark sky sites. In addition to it's optimum spectral and optical characteristics, the UHC/LPR filter offers important features that set it apart and result in the highest quality celestial views:
