I brought a 25mm from Amazon thinking that it was like my existing 25mm Plossl. (The larger one in the picture).

Ok, it was only $20. What I received has a noticeably smaller field of view and shows much CA around the field stop when I hold the EP up to the daylight. I think it may be a cheap Kellner.

I will give it a try when clear and if I change my mind about it capabilities, I will advise.
