I just compared the TE-11 (right picture) to the TE-10 (left picture) because I own both these eyepieces. I sold my TE-10 a while ago but could buy another one. In a former comparison, the TE-10 seemed to be sharper off-centre. Tonight's test did not prove this. Magnificication was 60x on both eyespieces, zoom on my Sony RX-100 II was 2.1; 400 ASA. Scope was my Kowa 883. Pictures are not cropped.
