Details

  • 85° degree visibility
  • 100gr

  • 1.25" Smooth Chrome Barrel (no "safety" groove)
  • All Masuyama eyepieces have the focal plane at exactly the transition between the lower and upper barrels.

User Comments "Brilliant EP's - easily much better than Televue" "To have the entire 85-degrees of AFOV sharp to the edge, the Masuyamas need a slower f-ratio scope, and f/10 is a good rule.  Nonetheless, there is plenty of crisp unaberrated central field to enjoy in even considerably faster scopes" "I was just too taken with the enjoyment of observing these clusters in the 6" Apo through the Masuyama to bother with anything else" Bill P "The Masuyama 32mm is killer in an Edge HD SCT" "For the globulars and nebula observed the Masuyama 85° quickly became my favorite during the testing, showing them brightly, richer in details than the other eyepieces"
