John, I also used to own a 27mm Panoptic which I have now sold for the 30mm 1rpd and a 21mm TV Vintage plossl. I have also tested several naglers and pans and I will say that the naglers are nice eyepieces and the pans as well.
You wanted to throw that 30mm 1rpd in the bushes?...well, that's EXACTLY what I wanted to do with the 30m GSO Superview the night that I tested it and compared it to the 30mm 1rpd. I know it is a personal thing when it comes to eyepieces, and when I get one with a blurry fieldstop,(the 30mm GSO Superview), I want to get rid of it right away , which is just what I did with the 30mm GSO the very next day after testing it.
My particular 30mm 1rpd has EXCELLENT on axis sharpness and the images are very pleasing 90% of the way out, maybe you had a lemon or something as these eyepieces are real "sleepers". I mainly use it for star-hopping to get to my destination and finding star asterisms is very easy having 1.6 degrees of sky in the 30mm 1rpd compared to only getting 1.2 degrees of sky with the 27mm Pan.
The edges are NOT that bad as it just shows a slight amount of COMA and not ASTIGMATISM. I can also use a 2" barlow on it to get 106x/43' field without any vignetting .
The 27mm Pan I had didn't barlow good at all, (it vignetted), because I didn't have a panoptic barlow interface , and I wasn't about to go out and buy one either.
I could also use an extension tube in the barlow and insert the 30mm 1rpd for a mag of 133x/36' field.
I guess it just boils down to asthetics when viewing thru an eyepiece, but I prefer to have one with a nice sharp fieldstop instead of a blurry one, and I will put up with the 10% of abberations and have that 1.6 degree field and a 5.8mm exit pupil.
~Clear skies to you John~
