Has anyone used these modified eyepieces?

What do you think of these microscope eyepieces
made to fit telescopes? For instance, they have
one that costs 500 Euros, is a 16mm with a 62 deg.
FOV. What would make someone buy that over a Nagler,
for instance? It's my understanding that all modern
microscope eyepieces are made to work with
"infinity focus" microscope objects so how do these
microscope eyepieces gel with a telescope?
In the past, one way to vastly improve a microscope's
performance was to put an telescope's orthoscopic eyepiece
in it in place of the microscope eyepiece. Result was
in most cases a wider, better corrected and flatter FOV
than with even compound microscope eyepieces.
I've no prejudices against using eyepieces from another
"specialty" for a telescope, I'll use whatever works,
including a barlow I have that was made with a negative
achromat from an eye testing machine! But in the past
I've seen where certain spotting scope eyepieces had been mated to
astronomical telescopes with less than desirable results.

I suggest asking Markus, he's from Germany, he may have few thoughts..

Here's something loosely (no pun intended) related. Binocular eyepieces
make great widefield oculars for the telescope. The pair of binos that
I scavenged for this purpose produced two very nice 32mm Kellners (I
THINK they are Kellners), and they were really close to 1 1/4 inches in
diameter. . .which led to an easy adaptation to make them fit quite
nicely in the focuser. Their field of view is wide and relatively flat
undistorted images extend almost out to the periphery. I kept one and
gave the other to a friend. Quite nice, they are, and an even better
bargain considering they came from a pair of binoulars that someone had
tossed.

trash. . .don't try to tell me you would have left them there) Howell

I am not sure about the EPs mentioned, however, I was able to find a Zeiss
9mm Orthoscopic microscope EP quite cheap. I have modified it so it fits
my telescope. It has given me great views of Jupiter and Saturn.
