No Yellow Here!!
This is a nice eyepiece. Contrast and edge of field sharpness are as they are advertised to be. I could not detect any yellowing around the edges like other owners have. Optically perfect to me. I was using it with a 12 LX200 UHTC. Maybe the others got early production units that had a few bugs in them, but mine is a 10.
Another Solid One
This is a solid eyepiece. Contrast and edge of field sharpness are on par with Tele Vue excellence. This is a keeper.
