Apertura #8 Light Yellow Filter - 1.25"



Apertura's Colored Filter has a Wratten number of #8, which is Light or Pale Yellow with a transmission of 83%.



Adding a yellow filter to your telescope's optical path will help enhance features on the Moon and Venus and increase the definition in comet tails. If you would like to observe Jupiter and Saturn, you can expect a yellow filter to help you see the orange and reddish features of the belts and zones penetrate and darken the subtle blue tones of the atmospheric currents.



Views of Mars will also benefit from adding a yellow filter. It will darken the maria, canal markings, and oases. It will also lighten the desert regions. This #8 yellow filter from Apertura will also sharpen the boundaries of Martian dust clouds. If you have a telescope with at least 11" of aperture, you can even use a yellow filter to improve detail on both Neptune and Uranus! Colored filters can be an invaluable aid in lunar and planetary observing by reducing glare and light scattering, increasing contrast through selective filtration, increasing definition and resolution, reducing irradiation, and lessening eye fatigue.



This Apertura filter is made out of high quality, solid plane parallel glass, anti-reflection coated to prevent glare. It has a full 26mm clear aperture, and is mounted in a black anodized aluminum cell. This cell is threaded on both sides to fit most eyepieces and stack with each other.



Please Note : The effectiveness of this filter depends on several factors, including the aperture and focal length of your telescope, the magnification being used, and the seeing conditions at the time. Remember that filters lower the amount of light that reaches your eye. You'll need an aperture of at least 8 inches for dark filters such as the #47 Violet, with only 3% transmission, the #25 Red with just 14% transmission, or the #38A Blue with 17% transmission.



This Product Comes with the Apertura Absolute Warranty!


  • Two-Year Warranty against product defects.

  • Three-Year Accident Replacement Program that begins after your initial 2 year warranty expires.

  • Your Apertura Absolute Warranty is transferable.
