    Thanks for the heads up on that Gabrielle. I have been interested in the Masuyama's since I bought the UO Ortho HD you mentioned a couple months ago (that turned out to be a keeper).

    Here is a list of the original Masuyama offerings that are also supposed to be coming available in the future. They work very well in binoviewers also.
    To that list can be added the 3" diagonal, 3" 80mm 52AFOV, 45mm 53AFOV and 50mm 53AFOV

    It looks like a must have eyepiece to me as well. I have the full line of KK Orthos. All but the 4 and 25 are the original ones sold as UO HD Orthos. The 4 and 25 are the more recent offering. The recent offering, IMHO, are actually a little better than the first ones. If KK is actually coming out with the Masuyama formula, judging by my experience with the UO HD Orthos, that 25W will be a must have eyepiece for me.

    They are an old eyepiece that was prominent in the 90s to early 2000s. Handmade 5 element in 3 groups. Some people used to refer to them as super Plossls though that is not a very accurate description.
    Many companies cloned them after they stopped production: Antares Elite, Celestron Ultima, Orion Sirius, Parks Gold, University Optics Supers and many others. These are commonly refered to as Masuyama clones to distinguish them from regular Plossls.
    For contrast and clarity they are very hard to beat.
    Here are a couple of schematics to show what the lens layout is.

    Hi Bill the Masuyamas are not the Othoscopics but a modified Plossl. Many observers rate the new KK HD (Masuyama Ortho) between the Zeiss Abbe and Zeiss Abbe II for performance. Dr. Masuyama-San definitely has a way of working glass.
