Not only are they a Masuyama "clone" but apparently so are the Tak LE's. There is even conjecture that Masuyama MAKES the Tak LE's

Hi Lewis,
The same eyepieces were sold as:-
Parks Gold Series
Antares Elite
Celestron Ultima
Orion Ultrascopic
They were essentially identical except for some slightly different coating specs. They all seemed to perform the same to me in the field. Optically they are excellent performers, outside of the 50~ degree fov and tighter eye relief in the shorter focal lengths. I like them a lot, really nice sharp contrasty images.
Meade also did a 5 element Series 4000 super plossl for a few years which was very similar and performed at the same level.
The Tak LE's use a similar optical design with a different housing. I am fairly sure they have fractionally longer eye relief (by about 1mm) for a given focal length than the others.
Cheers
