Orion Mars Filter – 1.25-Inch

The custom-designed Orion Mars Observation filter enhances contrast of virtually all surface features. Dielectric coatings transmit violet/blue (615nm) wavelengths where detail is rich, while blocking overbearing yellow/green (515nm to 615nm) wavelengths. Polar icecaps appear more sharply defined, and differences in landscape shading are nicely resolved. Polar hazes and cloud cover become visible. The filter’s high transmission makes it effective even in small telescopes. This custom-engineered Orion telescope filter comes with a protective plastic case.

Manufacturer’s Warranty: Limited Warranty against defects in materials or workmanship for one year from date of purchase. This warranty is for the benefit of the original retail purchaser only.

– 

  • High-performance observational eyepiece filter markedly improves views of Mars
  • Fully-coated Mars filter increases contrast to bring out subtle details on the disc of the red planet
  • When using the Mars filter on a clear, dark evening you’ll see polar ice cap detail, subtle mare shadings, dust storm and cloud activity
  • Eyepiece filter dramatically improves views of Mars even in smaller astronomical telescopes
  • Designed to fit 1.25″ telescope eyepieces with filter threads. Metal filter cell construction.
