Parks 25mm Kellner
The only reason I dropped the value rating to 9 is that the same basic eyepieces (but different focal lengths) are available from University for $35 as opposed to Parks $50. But it's still a great bargain in an eyepiece.

Parks 25mm Kellner
Not sure how you can rate this eyepiece a "10". Don't get me wrong, as Kellner's go, this one is wonderful. Really sharp and one of the most comfortable eyepieces I've ever looked through. But even at F/8 there was a little fall-off near the field-stop - which is what you should expect from a Kellner. And as the intro says, it's actually a bit wider than the advertised 40 degree AFOV, but still less than a good plossl.

Coatings are very good. This eyepiece is excellent on faint nebulae, (if they aren't too wide). You get more light passing through this ocular than most anything out there.

I give it a solid "8", which in my book is pretty good.
