This is a pretty nice eyepiece William Optics is selling. I have tested it in 70mm & 110mm refractors and a 10 f4.7 Dob. Flat and pinpoint to about 90 percent of field in my eyesight. The only issue I have is the contrast. I expected background to be a bit darker for a higher powered eyepiece. TV has the edge on it IMO. The real neat thing is great planetary views, considering it is not marketed as a planetary eyepiece? Very nice high powered wide field view but contrast lacks a bit -vs- TV Nagler design. A good economical alternative in a 82 degree design. I like it and think it is a good value and a good performer. Note: The 28mm UWAN rules!!
