About this item

  • Alstar 1.25inch Mars Filter is an excellent multi-purpose filter for viewing all features of Mars; polar caps stand out prominently; landscape features like mare and highland mountain ranges are easily separated and resolved; polar hazes and cloud cover become visible
  • The filter mount is precision manufactured from metal and is extremely thin to minimise shadowing and diffraction; machined of high quality aluminum and anodized black
  • Fully-coated Mars filter: An invaluable tool for any planetary viewer with an interest in the red planet; increases contrast to bring out subtle details on the disc of the red planet
  • High-performance observational eyepiece filter helps reveal feature details of Mars easily in any telescope; you'll see polar ice cap detail, subtle mare shadings; duststorm and cloud activity when using the Mars filter on a clear, dark evening
  • It's thread into the barrels of virtually any 1.25inch telescope eyepiece; the threads on both sides of the filter make it also possible to combine different filters
