I actually like the Huygens and Kellners that come with classic scopes. Part of the ethos. The H12.5mm and K22mm are great eyepieces.
I have recently observed with a Kellner 22mm and a HM 12.5mm.
I think it's hard to pin down which eyepiece one exactly is talking about as those .965s come in so many flavors.
My K22 is not that great, while the HM12.5 is really excellent:
I have some other .965" Kellners that I like very much, 25mm and 20mm. Also the 18mm Ortho seen on this picture is absolutely fantastic:
Now we've seen already so many great 1 1/4" eyepieces mentioned in this thread. Who can argue about smooth-side Televues or those beautiful volcano top Erfles ... but it's also great to stick to .965"s, maybe it because the scope can't be easily converted, or maybe because you just want the "real" classic observing experience.
In the case of the tiny HM 12.5, I watched Jupiter with it some times now. Awesome contrast and sharpness. And I found it just fascinating that there are only four lens elements involved, including the scope's objective! Thomas
