Colour Filters FS2B - (Set of 4)

by Antares
$67.99 USD

Colour filters enhance planetary imaging.  Every refractive system, (lenses, correctors, eyepieces, etc.) produces Chromatic Focal Shift: The different colors focus on different planes.  By isolating one color more detail will become apparent.  Always use a contrasting color to what you are observing.

Set (4) popular 1.25" filters:  #21, #56, #80A, ND13

Orange Filter (#21)

It helps increase the contrast between light and dark areas, penetrates clouds, and assists in detecting dust storms on Mars.  It also helps bring out the Great Red Spot and sharpen the contrast on Jupiter.  Also recommended for Uranus and Neptune.

Green Filter 53% (#56) 

It is excellent for the observation of Mars's polar ice caps as well as yellow-tinted dust storms on the Martian surface.  This filter increases the contrast of the red and blue regions in Jupiter's atmosphere as well as in the cloud belts and is also useful for enhancing lunar detail.  

Can be stacked with 80A (light blue filter)

Blue Filter (#80A)

It provides detail in atmospheric clouds on Mars, increases contrast on the moon, brings out detail in belts and polar features on Saturn, and enhances contrast on Jupiter's bright areas and cloud boundaries.  It also helps split the binary star Antares when at maximum separation.  Recommended for Mars and Saturn 

Neutral Density Filter 13% (ND13)

Looking at the moon through a telescope can be like staring into a flashlight.  This filter threads into your eyepiece and dims the view so you can see great detail and contrast on the surface of the moon!

Neutral density filters can reduce brightness across the visual spectrum without losing resolution, enhancing lunar-planetary observation.  Can be used stacked with color filters. NOT FOR SOLAR
