While Televues are certainly better than many (most) eyepieces, that doesn't meant they produce "sharp to the edge" and "pinpoint" images across the entire fov in *fast* scopes. For example, while a 22mm Panoptic is markedly better than an old Celestron 20mm Erfle in a dob at f/5.4, there is still noticeable coma and field curvature in much of the outer portions.
I think it is important to stress this because otherwise less experienced observers may rush out to buy expensive $$ high-end eyepieces thinking they will work miracles. A lot depends upon the observer's standards, their sensitivity to distortions, how fast their scopes are, their eyesight, the eyepiece's field of view, and collimation.
I found that a 21mm Pentax did just as well as the Pantopic, cost a bit less, & had better eye relief for eyeglass wearers. 8O
And, if one is willing to sacrifice the wider field of view, but still have more than a Plossl, the 22mm Epic is quite good for little money. (Admittedly, though, many find the Epic's 20mm eye relief too much.)
