MaxVision is a Chinese brand just like Explore Scientific, their eyepieces are basically identical except the MaxVision lacks Argon purging and has a barrel undercut.
Ernest over at
www.astro-talks.ru says the following about MaxVision eyepieces:
"An excellent eyepiece that may look a little simpler than Nagler or Explore Scientific, but produces image quality identical to its big brother from the Explore Scientific range and comparable to the Nagler type-6"
Eyepiece is in good condition and produces a nice image. Just the usual barrel marks from standard use. Comes with original box.
See images for a more detailed look at the eyepieces.
