Antares Set of (4) 2in Color filters #11, #21, #80A, #ND25
Color filters 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; brightness is not an issue with planets. Set(4) 2" Filters 2-#11,21,80A,ND25
