Lets see how many of S- PL 10x/20 eyepeice owners are here in binoviewers section, for those who doesnt read eyepeices forum on CNsmile.gif

 

So why I choose these ones, and not others?

 

Its becasue they are extremly rare, are real jewels for astronomers, with superb optical performance.

 

Not only that: they are made in about same year when Carl Zeiss Abbe Ortho (ZAO) eyepieces are made, when price per ZAO 25mm eyepiece was bit lower than 200 Euros,

while S-PL 10x/20 44 40 40 model costs bit more than 1000 Euros (yes, little bit more than 5x higher price than ZAO 25mm),

and, S-PL 10x/20 eyepeices are made in lower quantities than ZAO eyepeices- read much more RARE!!!

 

For those who dont know, S-PL 10x/20 focal lenght is 25mm.

 

They are made with serial numbers as follow:

 

44 40 39 - first run, oldest ones - variations with Zeiss logos, with Zeiss West Germany logo, and without any logo

44 40 39 (01) - next ones series with Carl Zeiss only logo

44 40 40 - latest run, and after that run, they are discounted forever. That run is made in several samples only, and are best performers of all in series.

 

So lets see some pictures....

I have one of these 44 40 40 and I am always on the lookout for a second one.  I have 2 of the first run 44 40 39 and they are great too. They are awesome in a binoviewer whenever I am not using my W-PL zeiss ones smile.gif.  The comfort level of using the zeiss eyepieces are top notch in my opinion.

Hello,

I also have a S-PL 10x/20  44 40 40 which I use for visual planet observing. Awesome APO eyepiece. But I have only one. I do not want to pay another 1000 € for a second one. For binoviewing I use the E-PL eyepieces.

If someone is really interested in obtaining mine, he can send me a private message. But as mentioned above they do come not cheap ...

I also have only one S-PL so I haven't used it in a binoviewer.  But I have pairs of 25mm Zeiss E-PL, Zeiss 444131, ZAO I, Clave, TMB Aspheric Ortho, Sterling Plossl, Astro Hutech as well as 24mm Brandon and TV Panoptic.  Lots to play with!

That pair you have, Denis, looks brand new.  How difficult was that to find 2 that were unused!

I'll happily pay far less for a 44 40 39 for the little difference there supposedly is lol.gif.

Last night I compared many of my 25mm on small clusters.  I am very near sighted so I believe this causes some heavy distortion, maybe astigmatism, at the edge of the S-PL.  This is for me and probably not for everyone.  But because of this it is not my favorite 25mm even if it is very nice on axis.  It might be different in a binoviewer.  So I tried it with a Nikon 1.6X Barlow and the view was amazing.  It was then my favorite.  At least last night.  I think it was higher magnification than the others, however.  But the view was just right with the seeing I had.  I think I will use it with a Barlow more often.  It gave a view I don't think I have seen before.  Similar to a 14mm eyepiece but wider FOV than my Supermonocentric.
