Orion 05598 1.25-Inch 25 Percent Transmission Moon Filter (Black) Telescope Filters Camera " Photo


Useful telescope eyepiece filter transmits 25 percent of ining light. Ideal for viewing crescent Moon phases for lunar viewing in smaller-aperture telescopes, for which less dimming is required. We are able to see the Moon at night thanks to sunlight reflecting off its rocky surface. When looking at the Moon through a telescope, bright reflected sunlight can produce significant glare. The Moon's disk, even at partial phases, is in fact so intensely bright reflected sunlight that observing surface details can be challenging due to the overwhelming glare. This glare can be so bright that it washes out most of the interesting lunar features such as craters, riles, mountains, valleys. The considerable brightness also reduces contrast on our nearest neighbor in the solar system. When the Moon is in its crescent phase, it does not produce as much glare as when it is full waxing, but filtration is still remended to achieve optimal view quality. When looking at the Moon in relatively small (60mm-80mm) telescopes, the brightness is not as distracting as in larger telescopes, but some filtration is required to get the best observations. To improve contrast tone down glare easily in these situations, we remend using a neutral-density 1.25 inch 25 percent Transmission Moon Filter. This inexpensive accessory threads directly into a 1.25 inch eyepiece barrel blocks 75 percent of the light gathered by the telescope, making for more fortable lunar views exhibiting higher contrast. Once installed on a 1.25 inch telescope eyepiece, the 25 percent Transmission Moon Filter will bring out considerably more lunar surface details thanks to the boosted contrast. Not only will more surface features details pop out, but you can study them in greater fort, thanks to Moon Filter reducing overall brightness without altering color.

  • Allows transmission of 25 percent of ining light
  • Reduces bright glare reflected off the Moon boosts contrast resolution of lunar surface features
