Quote:I think everyone assumes they are the same or similar, but to my knowledge no one has taken them all apart to confirm this. Given the non-matching focal lengths and the especially size differential between the 32mm of the M4000 5-elements and the 30mm Ultima/Orion/Antares/Parks I would hazard that their design can only be similar. I've taken a number of eyepieces apart and surprised that their implied design was not their actual one. At any rate, the M4000 5-element smoothies are wonderful performers with the 32mm being IMO a real gem for any 1.25" eyepiece in that focal length class.

Quote:I had a set of these back in the '90s. They were very nice, and I regret selling the set in a way. The short focal lengths had very little eye relief, but they were very good eyepieces--perhaps the best 50 degree eyepieces I ever owned.The ones I owned all said Made In Japan on them.
