Sorry I laughed out loud when I saw the image of shingles and Paolini claimed distortion was "minimal". The amount of pincushion distortion was shocking for a 62 degree eyepiece, and frankly the rest of Paoloni's review is superficial unquantified rubbish, ie worthless.


At least a side by side comparison with established premium eyepieces should have been provided that looks into th following with actual measurements from an optical bench:

A) sharpness off axis as a result of field curvature, spherical, coma and astigmatism, given the field curvature and distortion of the test telescope which also matters; Paolini didn't bother to mention the scope used;

B) lateral chromatic error near the edge of the field of view,

C) spherical aberration at the exit pupil, aka the "jellybean" or blackout problem affected certain eyepieces, notably Naglers;

D) eye relief as measured on an optical bench; Paolini clearly just takes the Televue data without any attempt to verify it by direct measurements.


Anyone with XW's, LVW's or nikons should keep them. No reason to switch.
