Set of 4 1.25" color filters (#11,#21,#80A,ND25), to enhance planetary imaging.
Every refractive system, (lenses, correctors, eyepieces, etc.) produce 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.
I've tried this set on a few nights. It's not a bad set. I am new to the use of filters in visual astronomy. I find it works very subtley. Not as much as I had hoped but maybe that's filters in general. The neutral density filter works on something bright like the moon but you will still be seeing black for a bit when you take your eye from the eyepiece after viewing a full moon.
