I have become convinced over my years of observing that the fewer optical elements in an eyepiece the better. I chose sharpness, contrast, brightness, eye relief, weight and cost. I rather like plossls, the 50deg FOV is usualy adequate and the on axis images are cool and sharp but the best eyepieces i ever used were some orthoscopics owned by a mate of mine.
I do sometimes appreciate a wide FOV and own 2 such eyepieces but I don't regard a wide FOV essential, I'm also not bothered by lack of edge of field sharpness provided it is not gross; the on-axis image is what counts for me. Now, this is only my opinion but i'm afraid Naglers don't cut it for me, have used them but would never wish to own one----I know, I'm weird but there's always one isn't there!
Well that's my quidsworth
Cheers to all
