Light Red 1.25
  • Eyepiece filters are an invaluable aid in lunar and planetary observing.
  • They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue.
  • These filters are made of high quality, solid plane parallel glass with excellent homogeneity.
  • They are anti-reflection coated to prevent glaring and ghosting.
  • All eyepiece filters are threaded to fit most 1.25″ eyepieces and offer a full 26mm clear aperture. Comes with a hinged, plastic case to keep your filter safe and clean when not in use.

#23A Light Red (25% transmission): On telescopes of 6″ aperture and larger the #23A does approximately the same functions as the #21 filter, but with stronger contrast and enhancement of marginally defined blue-green surface detail. Useful primarily on Jupiter, Saturn, and Mars. Increases contrast between Mercury and bright blue sky during daylight observations or during twilight.
