John and Eric
John once more you are spot on, the eyepiece suffers from astigmatism in the outer 20%. I bought it as calibration eyepiece and then found how good it is - if you forget about the seagulls it has very nice construction, very good coatings and no light scatter - I find all KK made eyepieces very nice indeed.
Eric if you just want to spend $100-150 it will be a better solution. Those eyepieces were $300-400 new...
